title: EXPERIMENTAL STUDY OF BEAM WITH EMBOSSED WEB

description: In order to reduce the weight and the material cost in the steel structures, a study on the slender sectional design has been continuously carried out. Steel beams with corrugated web have been widely used in the steel structures. The welding part between the corrugated web and the flange, however, is not straight, which makes the production costs increased. In order to compensate for this drawback, steel beam with an intaglio and embossed web (IEB) was invented by Innovation & Smart Heavy Industry Co., Ltd., South Korea. Plain plate is pressed to keep the upper and lower boundary of the web straight. This makes it possible to weld the flange and the embossed web by the automatic welding machine. In this study, four types of specimens were tested for comparison with plain H-shaped steel beam. Experimental results showed that the maximum load of the IEB specimens is about 1.3 times larger than that of the H-shaped steel beams. This is because the tension field action of embossed web significantly increased the post-buckling strength.

title: Estimation of Vehicular Collision Force for Bridge Columns using Computational Models

description: Although not commonly occurring, collisions of heavy vehicles with highway overpass bridge columns have happened in the past and resulted in catastrophic structural failures that paralyzed traffic on both the overpass and the highway below. A study that was conducted at South Dakota State University performed risk assessment and developed mitigation strategy for vehicular collision with bridge columns on South Dakota interstate highways. Since the collision force is dependent upon the stiffness of the structure and the approach speed of the crashing truck, a finite element (FE) dynamic analysis was performed in the study to evaluate the collision forces resulting from two different truck sizes crashing into a prototype bridge bent at three different approach speeds (55 mph, 65 mph, 75 mph). This paper covers the FE simulation that was performed using a computer software. The results indicate that the 600-kip vehicular collision force specified by AASHTO is a reasonable estimate for the load demand induced by an 80,000 lb tractor-trailer crashing into a bridge column at an approach speed not exceeding 55 mph.

title: EVALUATIONS OF FLEXURAL CAPACITY IMPROVEMENT METHOD FOR RC PIERS AND CISS FOUNDATION CONNECTIONS IN BRIDGES

description: Recently, Cast-In-Steel Shell(CISS) pile has been used as the foundation of bridges and a pier is directly connected to the pile. In this case, plastic hinge is generally formed at the connection between the CISS pile and reinforced concrete pier. To increase the flexural capacity of such structure, a proper improvement method is necessary for the connection. In this study, a steel tube, a steel pipe that has 270mm diameter with 4.5mm thickness, has been used to enhance flexural capacity of the connection and the effect by the such method was evaluated through cyclic compression-bending test. From the test results, it can be found that the flexure capacity is considerably increased by applying the steel tube at the connection when it was compared to a general RC pier with 10% larger diameter cross-section.

title: Slip coefficient of bolted slip-critical connections

description: The design philosophy of slip-critical connections is to utilize the friction force developed through the clamping force exerted by the pretension of the high-strength bolt. Therefore, the slip-critical connections can have resistance in the direction of the bolt shear. This resistance is affected by the bolt clamping force and slip coefficient on the faying surfaces. This research aims to increase the resistance of the slip-critical connections. Increasing the resistance of the slip-critical connections can be achieved by increasing either the clamping force or the slip coefficient. Thermal spray coating technology was used to increase the slip coefficient. Tests were conducted to investigate the effects of coated material (aluminum or aluminum-magnesium) and coating thickness. Compared to the blast-cleaned faying surface, thermal sprayed coating faying surface results in a greater slip coefficient.

title: Serviceability of low creep fly ash geopolymer concrete beams

description: In reinforced concrete construction, deflection control is an important performance criterion for their serviceability. The aim of the research described in this paper is to assess the deformation of cracked reinforced geopolymer concrete beams under long term service loading. The geopolymer binder is Portland cement free, using 85% of low calcium fly ash, 15% of GGBFS (Ground Granulated Blast Furnace Slag) and a sodium silicate/sodium hydroxide based activator. Firstly, geopolymer concrete drying shrinkage and creep were measured. Different curing conditions at elevated temperature were used. All experimental results are compared to predictions made using the Eurocode 2. Secondly, geopolymer concrete beams were subjected to short time bending tests leading to concrete cracking (pre-cracking tests). Beams were then stored under sustained loading for a period of 4 months. Both deflection and cracks were monitored versus time. Results show that, providing an appropriate heat curing regime, geopolymer concrete creep is much lower than that observed for OPC concrete and predicted by the Eurocode 2. As a result, the time-dependent deflection of geopolymer concrete beams measured after 4 months under sustained loading was always significantly lower than that of traditional OPC concrete beams. All results are showing that the crack widths of geopolymer concrete beams are significantly smaller than those expected for OPC concrete beams according to fib model code 2010 for both short and long terms tests. It is concluded that low calcium fly ash-based geopolymer concrete is a promising option for precast applications.

title: Analyzing Databases in the Taiwan Bridge Management System Using Big Data Approaches

description: This paper describes some preliminary results of this research. Before conducting a comprehensive big data analysis of the whole system of Taiwan Bridge Management System (TBMS), a pilot test was performed to explore possible outcomes. A total number of 34,099 records each having 305 fields of 24 bridges in a specific region were analyzed using the famous R software. The resulting correlations between inventory fields and deterioration of bridge components are categorized in three types: explicable, inexplicable, and irrelevant. For those inexplicable correlations, interviews with experts are found necessary in order to explore useful or meaningful maintenance information. Two more similar tests are also being planned for two groups of bridges that are nearby sea or solely in the mountainous area. In addition to the correlation between a specific deterioration and all existing inventory fields, other maintenance information such as frequently maintained components as well as their maintenance frequencies and costs, and other crucial relationships among fields in the TBMS are highly anticipated in this research in order to establish beneficial suggestions to the bridge maintenance strategies in Taiwan.

title: A RETROFIT METHOD FOR OLD PRECAST PANEL BUILDINGIN ULAANBAATAR, MONGOLIA

description: This study is devoted to the development of improved methods and computer programs for predicting the seismic performance of existing precast panel structures. It is necessary to establish an experimental investigation as well as to develop a more detailed analysis and design procedures related to seismic design considerations for existing precast panel structures. The nonlinear behavior of precast panel buildings depends on the panel contact zones and this feature should be incorporated into the analytical models for the elasto-plastic nonlinear analysis. This study presents a newly designed finite element program developed on Fortran software for the nonlinear analysis of typical precast panel buildings. With the aid of this finite element program, eight different analytical models were designed and performed to simulate the nonlinear behaviors of panel contact zones under lateral loading. The analytical models were composed of four control models without any retrofitting and four models retrofitted using a steel bolted plates at the both horizontal and vertical joints between associated panels. A two-dimensional elasto-plastic nonlinear analysis with pushover method was performed on the analytical models, to obtain lateral force and displacement relationship. The simulation results illustrate the comparisons of lateral force-displacement curves for both the non-retrofitted and the retrofitted models. It was observed that all the retrofitted models showed a significant increase in strength and ductility.

title: Failure Literacy in Structural Engineering

description: The history of the development of practice in many engineering disciplines is, in large part, the story of failures, both imminent and actual, and of the changes to designs, standards and procedures made as the result of timely interventions or forensic analyses. All engineers, and more particularly structural engineers, should be failure literate. Failure literacy means knowing about the critical historical failure cases that have shaped the profession, not merely the surface technical details, but the environment, the communications difficulties and the procedural issues. In the U.S., an intensive effort has been under way for nearly a decade to promote failure literacy in engineering education and practice. A number of educational resources have been developed by the Education Committee of the American Society of Civil Engineers Forensic Engineering Division (ASCE FED) to make it easier for engineering students and practicing engineers to learn from failures. Some landmark failures include the Tacoma Narrows bridge collapse, 1940, the Point Pleasant/ Silver Bridge collapse, 1967, the Ronan Point building collapse, 1968 (U.K.), the 2000 Commonwealth avenue building collapse, 1971, the Bailey

title: IMPACT OF PREDICTING BRITTLE FAILURE MODES ON SELECTION OF LIMIT STATES OF VERTICALLY-IRREGULAR TALL BUILDINGS

description: The proper definition of structural failure of irregular structures is a critical element in building vulnerability assessment. Shear force demands may be the main cause of failure under earthquake loading. This increases the uncertainty related to the definition of the limit states of irregular buildings. The present study thus focuses on the assessment of brittle shear failure on the performance criteria of vertically irregular tall buildings. Five 50-story structures are designed using international standards to represent code-conforming tall buildings with main vertical irregularities. Detailed simulation models are used to assess the failure modes of the buildings under the effect of far-field and near-source earthquake records. Experimentally verified shear strength models are adopted to monitor the shear supply-demand response of the reference structures. Based on the comprehensive results obtained from incremental dynamic analyses, it is concluded that shear modeling is essential for the reliable assessment of vertically irregular buildings. The limit states of the reference buildings are significantly influenced by the characteristics of earthquake records and the irregularity type. Unlike the behavior of the buildings under the far-field earthquake scenario, which is controlled by flexure, the collapse prevention limit state is significantly influenced by the member shear response under the effect of near-field earthquakes. Accordingly, improved limit state criteria are proposed, which supports the reliable earthquake loss estimation of tall buildings with different vertical irregularities.

title: VIBRATIONAL PROPERTIES OF EARLY SHOWA PERIOD BILLBOARD ARCHITECTURE FOR RENOVATING DENSELY BUILT-UP WOODEN HOUSE AREAS

description: We report the progress of our research on buildings and their surroundings for disaster prevention in Chuo-3, Ota City, which is an area in Tokyo, Japan with Densely Built-up Wooden House Areas. In a previous paper, we reported the results of an exhaustive survey of 383 buildings and roads in the northwest area of Chuo-3. As a continuation, in this paper, we present findings from an exhaustive survey of 426 buildings and microtremor measurements on the ground in a more widespread area. As a result, we found evidence of early Showa period billboard architecture. We subsequently measured the dimensions of the billboard architecture and surveyed the materials of the walls, roofs, windows, etc. Furthermore, we constructed a standard billboard architectural model and conducted eigenvalue analysis to evaluate their respective vibrational properties, such as the natural frequency and vibrational mode. Lastly, sensitivity analyses were conducted on the floor rigidity or materials of the walls.

title: Damage Modeling and Assessment for Brittle Materials

description: Damage Modeling and Assessment in Frictional MaterialsS. Yazdani1, A. Salehi2, A. Saboori3, B. Jahani4, and S. Boregersen51Heyer Engineering, Fargo, USA2Dept. of Mechanical and Industrial Engineering, UIC, Chicago, USA3Department of Civil and Environmental Engineering, UC, Davis, USA4Dept. of Mechanical Engineering, NDSU, Fargo, USA5SEBCorp, Eagan, USAAbstractObserved nonlinearities in frictional and brittle solids such as concrete, rocks, ceramics, and some composites arise mainly due to the nucleation and propagation of microvoids and microcracks. Microcrack formation, propagation, and coalescence damage the material and renders it more compliant. Microdefects and cracks are also usually irreversible and cause strong anisotropy in the response to loads. This paper presents a damage mechanics model to capture material anisotropy and damage under multiaxial stress states for proportional and fatigue type loadings. The theory is cast within the generally accepted principles of thermodynamics with internal variables where the dissipation inequality is invoked to develop loading surfaces. Flow rules for the onset of inelastic deformations is provided and specific damage laws are proposed. The model extension to the cyclic and fatigue type loading is presented and numerical results are provided with comparison to the available experimental data.

title: Seismic Performance of Six-story Fabricated Steel Frames under Pseudo-Dynamic Testing

description: In order to study the seismic behaviors of fabricated steel frames with bolted beam-height adjustable steel beam-to-column connections (BHA connections), a six-story steel frame was designed to run pseudo-dynamic experiments. Experiments were first carried out with the steel frames with and without BRBs under three different types of seismic records under 35gal and 70gal. Then the seismic records of EL_CENTRO amplified from 220gal to 1600gal were loaded on the braced frame. Results showed that there was no detachment, sliding, or yielding detected in BHA connections. After BRBs were installed, the story drift and the top-story maximum displacement could easily meet the codes, and the structure was still working in the elastic stage under 620gal. It could therefore be concluded that BHA connections have excellent seismic performance and they are suitable for application in fabricated steel frames. The braced frame using BHA connections has good lateral stiffness and energy dissipation capacity.

title: Comparison of Cooling and Heating Requirements Between Brick Veneer and Fibro Cement Walling System

description: Space cooling and heating in residential sector is significant contributor to energy consumption in Australia. Therefore, it is important to reduce the cooling and heating requirements. The selection of a good walling system helps to save energy by homes. This research compared the thermal efficiency of a modern house (constructed using brick veneer walls with concrete floor slab) with an old house (constructed using fibro cement walls raised timber floor) using the AccuRate simulation tool. A standard house with two living rooms, one kitchen, one laundry and four bedrooms are simulated in a Sydney Suburb in Australia. It was found that modern house showed lower inside temperature variation than the old house all year around. The results also showed that the modern house has a lower energy consumption for space heating and cooling than the old house. The annual energy use for space heating and cooling in both the modern house and old house were 5197 kWh and 15,712 kWh respectively. Moreover, the annual energy costs were found to be $1,403 and $4,242 respectively for modern and old houses. The modern brick veneer house saved about 33 % of energy compared to old old house. When the net present value of the energy cost for f both houses over 50 years is computed, the energy cost of modern house was found to be $25,629 while it of old house is was $77,488 for the old house

title: FRCM SHEAR STRENGTHENING FOR CONCRETE BEAMS

description: This paper presents the results of an experimental study carried out to examine the efficacy of Fabric-Reinforced Cementitious Matrix (FRCM) in strengthening RC beams susceptible to shear failure. In this paper, seven (7) shear-critical RC beams, of 2,500 mm in length, 150 mm in width, and 330 mm in depth, were tested under three-point loading until failure. Two main test variables were considered, which are:a) Strengthening material: carbon, polyparaphenylene benzobisoxazole (PBO), or glass FRCM.b) Strengthening application pattern: a single full-length FRCM plate or a set of intermittent and spaced FRCM strips were applied along the critical shear zone.The test results confirmed the efficacy of FRCM strengthening in improving the load capacity of shear-critical RC beams. The FRCM-strengthening contributed to increases in the load capacity ranged between 31% and 100% compared to the reference specimen. The full-length strengthened specimens generally showed a better strength enhancement compared to the intermittent counterparts when using the same FRCM material. Such intuitive observation assures the importance of the amount of strengthening material applied in the critical shear zone. Besides, specimens utilizing carbon fibers in its FRCM strengthening material showed the highest strength enhancement among the three systems.

title: INCREASING ROBUSTNESS OF RC STRUCTURES UNDER COLUMN LOSS SCENARIO

description: This paper presents simple and effective technique to enhance robustness of reinforced concrete frames toprogressive collapse under column loss scenario. The response of the mitigated frames is analyzed usingfiber force-based finite element analysis and applying displacement-controlled nonlinear static pushdownat the location of failed column. The technique includes addition of external unbounded steel cables to thecontinuous beam in each floor at anchorage and deviator locations. The cables transfer the loads abovethe failed column to the anchorages and deviators that are assumed to perform as rigid arms, which in turnredistribute the loads to adjacent columns. The numerical model computes the frame building progressivecollapse robustness using push-down analysis to simulate a column elimination and estimate the effects ofcable catenary action on the frame. Two-dimensional RC frame of six stories and four bays was adoptedin the study. The numerical results demonstrate the prospect of resisting progressive collapse of RCstructures by implementing the presented technique.

title: A Computational Framework for Holistic Life-Cycle Design of Buildings

description: This paper combines building information modeling with advanced structural modeling to optimize the design of building components using a life-cycle perspective. A new object-oriented software framework that extends an existing program is presented. It creates information-rich finite element models from industry foundation class files that are exported from building information programs. In addition to models for structural responses, the new components contain models for construction cost, repair cost, environmental impact cost, and human health cost. Random variable objects represent uncertainties in material properties, hazards, and cost models. Similarly, design variable objects represent decisions, such as structural dimensions and materials. All costs are summed and the expected value of this sum is employed as a decision criterion. This paper presents the software framework and a demonstration application.
