title: Shear Buckling Tests on Stiffened I-Shaped Plate Girders: Flat Versus Low-Frequency Sinusoidal Webs - Flat Plate Girder
title: in Collaborative Research: Shear-Buckling Mechanics for Enhanced Performance of Thin Plates

description: Shear buckling tests were conducted to assess the performance of the first fabricated LFS web girder prototype, compare it to a traditional flat web prototype, and study the mechanics of web shear buckling in welded plate girders at the scale of a realistic bridge girder.
description: Thin steel plates are commonly used as structural elements in buildings, bridges, towers, aircrafts, etc. Due to their slenderness, these plates are susceptible to buckling under shear loading, thus limiting their capacity. The recent research shows that many existing models do not represent the true mechanics of ultimate shear buckling. This project will investigate and advance the knowledge of shear buckling response, thus leading to improved economy, durability, and safety of structures that use thin plates. The focus of this study is on steel plates, but it lays the foundation for other materials such as aluminum and composites that can be considered in future work. This project also addresses the grand challenges recently issued by the American Society of Civil Engineers (ASCE): (a) significantly enhance the performance and value of infrastructure projects over their life cycles by 2025, and (b) foster the optimization of infrastructure investments for society. The results will increase cost efficiency via decreased material usage; enhance robustness via increased ultimate shear strength; and reduce occurrence of buckling and increased resilience to unexpected loads (e.g. with fewer required repairs) via increased buckling load capacity.

The overall objective of this project is to comprehensively investigate the mechanics of shear buckling behavior in steel plates, thus leading to (a) new predictive models that capture the true mechanics, and (b) design modifications that increase economy, robustness, and life-cycle performance. The research plan involves both nonlinear finite element studies and experimental tests. A detailed examination of the stress patterns and load redistribution from the elastic buckling stage to the ultimate postbuckling capacity will be the primary focus. Physical tests will explore new panel configurations, and potential material optimizations will be identified based on finite element mechanics studies. Experiments will be conducted using facilities at Lehigh University to examine the shear buckling performance of steel plate girder specimens, both with and without bending moment. The data from these tests will be used to directly validate the computational modeling approaches.

title: in RAPID: Performance of Reinforced Concrete Structures with Externally Bonded Fiber Reinforced Polymer Composite Retrofits in the 2018 Anchorage, Alaska Earthquake

description: Externally bonded fiber reinforced polymer (EBFRP) composites can be used to seismically retrofit structures in a simple and economical manner. However, lack of documented evidence of their performance during an earthquake still limits their widespread adoption. In this project, the effects of the November 30, 2018, earthquake (magnitude 7.0) in Anchorage, Alaska, on the performance of EBFRP composite retrofits in reinforced concrete buildings, were studied. This study, for the first time, provides information on the performance of EBFRP retrofitted structures in an earthquake that occurred in the United States. 
The main objective of this project is to collect perishable data on EBFRP response during the 2018 Alaskan earthquake to improve understanding of the performance of EBFRP-retrofitted structures. The data collection activities in Anchorage, Alaska, coordinated with the National Institute of Standards and Technology (NIST), included the following: (1) photographic documentation of damage to EBFRP retrofit systems (e.g., delamination, rupture, and environmental degradation), and (2) identification of in-situ characteristics of the EBFRP utilizing non-destructive (e.g., acoustic sounding and infrared thermography) and semi-destructive (e.g., bond pull-off test) methods. Where permissible, small samples of EBFRP were collected for chemical and thermal analysis to determine the extent of environmental degradation in EBFRP.
description: Scanning Electron Microscope (SEM) images of the EBFRP sample cross-sections from Ted Stevens International Airport and McKinley Tower were recorded to investigate potential degradation of the resin matrix, fibers, and their interface. For the microscopy analysis, pieces of EBFRP were cut and impregnated in epoxy. Images from the exterior and interior samples were compared to determine if environment had affected its microstructure. The presence of air voids and a non-uniform distribution of fibers in the matrix was observed in the cross-sectional SEM images of EBFRP retrofits from TSIA and MKT.

title: Wall Boundary Element Test #13
title: in NEESR: Seismic Performance of Conventional and Innovative Special Structural Walls

description: Uniaxial test of a reinforced concrete wall boundary element #13
description: The project explored design and performance limits for structural walls, considering both conventional wall construction practices and innovative construction practices. A principal finding of recent earthquakes (in 2010 and 2011) and laboratory tests from 200 to 2010 is that wall performance is limited by stability and ductility capacity of the flexural compression zone. Given this critical issue, a series of studies on conventional walls and boundary elements constructed with innovative materials (HPFRCC) to establish performance limits for flexural compression failures in reinforced concrete structural walls. Tests were designed to acquire knowledge, improve construction practices, and advance simulation tools. The primary research outcomes include: 

(1)	Completing  tests of eight ordinary boundary element (OBE) prisms at UCLA. The test specimens were detailed according to ACI 318-11 21.9.6.5 with the goal of assessing failure modes and strain capacities as influenced by concrete cover, configuration of transverse reinforcement, and spacing of transverse reinforcement. Based on the tests, a relationship used to assess buckling of longitudinal reinforcement was extended to wall boundaries with typical OBE detailing. 
(2)	Completing tests on 13 special boundary element (SBE) prisms at UC Berkeley. The tests investigated the role of boundary element detailing and wall thickness. The tests indicated that the strain capacity of relatively (< 12 inches) walls with ACI 318 code compliant SBE detailing was less than one percent and that improved detailing or high-performance, fiber-reinforced concrete did not improve the strain capacity significantly. 
(3)	Conducted tests on seven, approximately one-half scale wall panels represented the base of roughly 8 to 10 story walls in a moderately tall building.  The primary test variables were the configuration and quantity of boundary transverse reinforcement, the depth of the neutral axis, and the wall thickness. The test provided essential data to develop a new, displacement-based model for predicting the drift capacity of structural walls with SBE. 
(4)	Developing code change proposals that were approved for ACI 318-14 and additional code change proposals that have been approved for inclusion in ACI 318-19. 
(5)	Creating and documenting a detailed dataset that was uploaded to DesignSafe-ci Data Depot that can be used for future reserarch.

title: Cyclic Laboratory Test Data of Soil Samples from Adapazari, Turkiye
title: in Cyclic Laboratory Test Data of Soil Samples from Adapazari, Turkiye

description: Severe liquefaction-induced ground failure was observed in the Adapazari region following the 1999 Kocaeli, Turkiye earthquake. Many of the soils that failed were fine-grained and not traditionally considered susceptible to liquefaction at the time of the earthquake. Geotechnical site investigations and cyclic laboratory tests performed on the soils were presented by Sancio (2003) and Bray and Sancio (2006). The goal of the present study is to present the raw laboratory test data performed on undisturbed samples from the region of severe ground failure that was developed from the past studies. The data are presented in Excel files containing a summary tab showing the key parameters of the test results along with the measured raw data from these tests. Moreover, the tests performed to determine index properties of each specimen, which are Atterberg limits and/or grain size distributions, are presented on separate tabs, if applicable. The raw data is a digital version of plots originally presented in the Sancio (2003) PhD dissertation, and the naming of the specimens along with key parameters is provided therein.
description: The presented Excel files consist of raw cyclic triaxial and cyclic direct simple shear testing data on undisturbed samples collected after the 1999 Kocaeli earthquake in Turkiye. Most of the cyclic triaxial tests were performed at the ZETAS geotechnical laboratory in Istanbul, and some cyclic triaxial tests along with cyclic direct simple shear tests were performed at the UC Berkeley geotechnical laboratory. The region is subdivided into 7 sites where various numbers of borings were conducted. A piston sampler was used to obtain the undisturbed samples from the borings. The abbreviations used in the Excel files are explained through a README file which is presented along with the Excel files.

title: Data Report on Local Perceptions on Building Safety and Building Performance after the 2019 EF4 Linwood Tornado
title: in Local Perceptions on Building Safety and Building Performance after the 2019 EF4 Linwood, Kansas Tornado

description: This report describes the data collection process, data cleaning process, and summary statistics for two survey efforts addressing local perceptions on building safety and expectations of building performance during tornadoes.
description: Kansas has the second-highest frequency of reported tornadoes in the U.S., yet, most counties and many local jurisdictions lack modern building codes with basic lateral force system requirements, thereby minimum levels of protection against tornadic winds. On May 28, 2019, an EF4 tornado struck north-eastern Kansas; the 32-mile long path destroyed approximately 40 building structures and damaged nearly 200 building structures. A post-tornado investigation by the researchers revealed a lack of continuous load path, and in some cases, lacking even basic structural elements, such as anchor bolts or mechanically fastened walls to foundations. These statistics and observations led the research team to question what were local perceptions on building safety and expectations of building performance during tornadoes, what would happen if a tornado were to hit closer to the University of Kansas (KU) campus, and what types of better designs are known of or offered by local contractors. This research project includes two survey efforts addressing research questions on local perceptions on building safety and expectations of building performance during tornadoes. The first survey effort documented local contractors’ perceptions of tornado-resistant residential building design. The first survey effort utilized a convenience sample of local contractors attending a continuing education course on how to provide a continuous load path. The survey was administered in person; no personally identified information was collected. The convenience sample size was 45 and resulted in a response rate of approximately 60%. The second survey effort was initiated as part of a senior capstone project. The capstone project assessed the risk perception and sheltering decision of the KU campus community after the EF4 Linwood tornado. It was administered online using email listservs for KU’s Schools and Colleges for recruitment, inviting participants to complete a short Qualtrics survey. The response rate was low, with only 228 responses. This publication contains the Institutional Review Board Protocols, two Survey Instruments, which included in-person, and virtual surveying modes and questions on tornado risk perception, and, as well as the data for the contractor survey and the capstone project.

title: Large scale testing for roof overhangs aerodynamic analysis using the Wall of Wind experimental facility
title: in Wind induced loads on hip roof overhangs of low rise building (Phase II)

description: The Laboratory for Wind Engineering Research (LWER) of the Extreme Events Institute (EEI) at Florida International University (FIU) was commissioned by the Florida Building Commission / Florida Department of Business and Professional Regulation to investigate the wind-induced loads on roof overhangs of low-rise residential buildings. The large-scale experimental campaign was carried out at the Wall of Wind (WOW) Research Experimental Facility. The setup comprises of six 1:10 scaled model configurations (2 ft, 4 ft 6 ft inclined overhangs) and different roof slopes (4:12 and 6:12) of a low-rise hip roof building. Data in this project can be used for statistical analysis for roof overhangs of hip roof, or a comparison between large scale testing and small-scale testing, and a reference for studying the behavior of overhangs, walls and soffit for any other roof type rather than the hip roof. In addition, the relation between the soffits and the walls can be driven from the data by carrying out regression and correlation analyses using the peak pressure coefficient and pressure time history, respectively. This project is unique because it is the first time to conduct a large-scale testing to study the wind induced loads on roof overhangs. Moreover, the large-scale testing gave the privilege to install high resolution pressure taps for capturing the pressure all over the surface. The audiences are anyone interested in wind tunnel testing for components and cladding of low-rise buildings, building commissions, and structural engineers.
description: Roof overhangs were tested by installing pressure taps along both the upper and lower surface and the underneath walls. The outcome was the pressure coefficient among the surfaces of walls, soffit and overhangs that can be used for many statistical analysis or calculating peak pressure along the surface to calculate wind loads or uplift forces. The data can be reused for training machine learning models to predict surface pressures

title: Poster for Social Institution Resilience Theory: Implications for Community Resilience Planning Models

description: An understanding of community resilience and how hazard events impact communities can lead to better policies and decisions designed to achieve community resilience goals. Communities achieve resilience when individual and household needs are equitably met through functioning physical and social systems. Social institutions, such as education and health care, help communities meet different needs. This poster presents a social institution resilience theory that can guide the integration of social institutions within computational modeling environments. The proposed theoretical framework combines the concepts of needs theory, community capitals, disaster phases, and social vulnerability. The research methodology utilized a systematic literature review and three case studies to answer the question of what community capitals facilitate or constrain a social institution’s ability to equitably meet community needs during different disaster phases. Findings suggest that the significance of community capitals depends on disaster phases. For example, a response model that predicts if a hospital can meet basic survival needs, such as emergency room services, may be valid with components that measure natural and built capitals. Meanwhile, a recovery model that predicts how long after a disaster it would take before a school district will be able to meet higher needs, such as students' need for belonging, would not be valid unless it included measures of social, human, political, and financial capital. The proposed social institution resilience theory will help researchers understand the complexity of and the capitals that impact community resilience.
