title: NATURALLY STRAINED YIELD SURFACE SHAPE ESTIMATED UNDER PRE-DEFORMATION OF TENSION AND TORSION

description: The purpose of this study is to investigate the shape of yield surfaces formed under large pre-deformations, based on the Natural Strain theory, and to make clear the mechanism of the development of anisotropy of yield surfaces under large deformations. In particular the shape of yield surfaces obtained after applying the pre-deformation of tension and shear with proportional loading states is examined. Using pure-copper test pieces already pre-deformed, proportional loading tests were carried out again changing the ratio of tension and torsion to determine yield stress in each direction of the stress space. The yield stress was estimated by examining the slope of tangent for the principal deviatoric stress-deviatoric strain curve in proportional loading tests. It was revealed that the shape of the yield surface becomes convex at the side of pre-deformation and becomes flat in the opposite direction of the pre-deformation. Moreover, the shape of the estimated yield surface was compared with the shape of conventional proof stress. Consequently, it became clear that the shapes of both yield surfaces almost coincide at the side of pre-deformation, but on the opposite side, the yield surface by proof stress becomes smaller compared with the estimated yield surface.

title: THE EFFECT OF RESIDUAL STRESSES IN FILLET WELDS ON THE FATIGUE BEHAVIOR: A LEFM APPROACH

description: Residual stresses are present in many civil structures due to manufacturing actions causing plastic deformations. Nevertheless, these stresses are not often taken into account when considering the design of these structures, especially when assessing fatigue problems. This remains true for orthotropic steel bridge decks. Due to their many complex welding details, these decks are sensitive to fatigue. To increase the understanding of the fatigue behavior of welded details, an improved analyzing tool using linear elastic fracture mechanics is proposed in this paper. Apart from the fatigue life of the weld detail, the crack propagation and crack growth direction are also evaluated with an XFEM model. Application of this method to the case of the orthotropic steel Temse Bridge in Belgium results in crack propagation very similar to reality. It also demonstrates that the fatigue calculations need to include residual stresses to comply with the real behavior of crack propagation.

title: A NEW METHOD TO DETERMINE TENSILE-STRAIN SOFTENING CURVE OF QUASI-BRITTLE MATERIALS

description: Based on weight integration to obtain a closed solution of cohesive crack problem, a new method is proposed to determine the tensile-strain softening curve (TSC) for quasi-brittle materials. The key technique is to determine the weight function by superposition of the solution with different fictitious crack lengths to satisfy a given crack opening displacement within cohesive crack surfaces. As an example, a central crack problem under uniform tension with given crack opening displacement in the fracture process zone (FPZ) was analyzed, the corresponding TSC was determined, and then the solution for stress and displacement field was obtained.

title: NON-LINEAR ANALYSIS OF THREE-PINNED CIRCULAR ARCHES

description: Because a three-pinned circular arch is statically determinate, when it is subjected to a uniform radial load q, linear in-plane analysis has shown that the uniform load will produce quite simple internal actions: a uniform axial compressive force N = qR and zero-bending moment, where R is the radius of the arch. This is consistent with equations in textbooks for structural mechanics. However, the non-linear behavior and buckling of three-pinned arches are very different from their linear counterparts. The uniform radial load can produce significant bending moments in the three-pinned arches, and the value of the uniform axial compressive force in the three-pinned arches is greater than qR. In addition, it is also shown in this paper that the solutions for the in-plane elastic buckling load of three-pinned arches available in the open literature cannot predict their in-plane buckling loads correctly.

title: LIMIT ANALYSIS UNDER LATERAL LOADS OF MASONRY VAULTS UPDATED BY Omega-WRAP

description: In this paper, the structural behavior under lateral load of a masonry-barrel vault, strengthened by new technology by applied Carbon-Fiber Reinforced Polymer (C-FRP), is discussed from both theoretical and experimental points of view. The C-FRP is applied such as to assume an ? shape around a concrete core at the vault extrados. A theoretical prediction of ultimate strength was derived in agreement with observations during the experiments (e.g., masonry crushing, FRP rupture, debonding, sliding along the mortar joint). A lower-bound limit-analysis approach was developed that can handle the shear strength of each ideal section given by the Mohr-Coulomb friction law (for the mortar joint). It can also handle other non linear Italian Code relations (for CFRP ?-Wrap reinforcement) at a given level of normal compressive stress resulting from the previous step.

title: Development of a thermal water pump with steam-air for agriculture

description: This research purpose is to design and construct an automatic thermal water pump (TWP) with steam-air and study the appropriate amount of air added to a steam working fluid for use within the system. Direct contact cooling was employed. The system consisted of feed water tank, liquid piston tank, heating tank, storage tank and well tank. The objective is a feasibility study of the air quantity in the LT was set at 0%, 10%, 20%, 30% and 40% with a constant discharge head of 1 m, a constant suction head of 0.8 m and 1 hours test time. However, in this research we uses heater as a substitute of renewable energy. Thermal energy input was supplied by an electric heater as a substitute of renewable energy. An operation of the pump consisted of 5 stages: heating, pumping, vapor-flow, cooling and water suction. Results of the experiment use air in conjunction with system the maximum pumping efficiency 0.01903% at quantity of air 10% the maximum pumped water 96.4 l at quantity of air 0% the maximum numbers of pumping cycles 17 cycles at quantity of air 40%. As the quantity of air increased, the numbers of pumping cycles increased but the pumped water could be reduced accordingly, which affected the pumping efficiency. However, HT temperature could be further reduced. Using air in conjunction with the steam working fluid could lower the working temperature suitable to solar application.

title: On the economic prospects of alternative powertrains in car transport

description: Passenger cars are one of the largest producers of carbon dioxide. These emissions could be significantly reduced with the increasing use of alternative powertrains. However, alternative technologies especially battery electric vehicles and fuel cell cars are currently very expensive and not competitive with conventional cars.  This paper investigates the long-term prospects of environmental friendly alternative powertrains in a dynamic framework up to 2050 for average conditions of EU-15 countries. We conduct a dynamic technical and economic analysis and investigate when in the future these vehicles could become  under favorable conditions  economically competitive. To evaluate the economics we calculate the transport service costs per 100 kilometers driven. The major conclusions of this analysis are: With respect to the economic competitiveness of alternative powertrains compared to conventional vehicles in the most favorable case (long distance driven cars) battery electric vehicles will enter the market by about 2025. Fuel cell vehicles powered by hydrogen will become competitive later, by about 2040. However, the major uncertainty is technological learning especially in the case of batteries and fuel cells.

title: IDENTIFYING THE EFFECTS OF EXCESSIVE DEFLECTION IN REINFORCED CONCRETE BEAMS

description: In framed reinforced concrete structures, the beams transfer the dead and live loads tothe column and then to the foundation. When there are observed structural failures insystems supported by the beam, the functional state of the beams should be ascertainedbefore any further detailed investigations are initiated. The correct diagnosis of thesource of the problem is essential to design an effective rehabilitation scheme. Simplevisual inspections corroborated with field tests for true beam horizontality can providethe lead information that will guide the clients? scope of further investigations. Casestudies addressed the research questions; the research data was collected by reviewingprevious investigation reports on a three-story building, then conducting physicalinspections and simple site experiments to identify the lead information. The resultsreveal that multiple cracks observed in the partition walls, especially in the secondfloors, were as a result of excessive deflections in the beams supporting the first andsecond floors. Subsequent investigations confirmed this lead information andappropriate rehabilitation schemes were adopted.

title: Wave Energy Resource Assessment for Southeast Asia

description: Wind-generated ocean waves have the potential of contributing a significant amount of renewable energy. The conversion of ocean waves into sustainable electrical power has been increasingly concerned and the need for wave energy resource assessment therefore becomes essential. This paper explores the wave energy potential of Southeast Asia (SEA) by applying numerical wind-wave modelling. In particular, the spectral wave model with SEA domain and resolutions between 1? and 100m was run for one-year period. The boundary conditions were obtained from another spectral wave model with the coarser mesh of Indo-Western Pacific domain, comprising of the Indian Ocean and part of western Pacific Ocean ranges between 20? to 140? E and 60? S to 35? N. The modelling output presents the map of annual mean wave power of the region and it reveals that wave power is highest in the western side of Sumatra island, the Andaman Sea part offshore of Myanmar, followed by the South China Sea area between Vietnam and the Philippines. Within the Singapore Strait, wave energy is found to be strongest in the southeast, and showing the greatest magnitude during northeast monsoon.

title: An enhancement of the daylighting from side-window using two-section venetian blind

description: In the tropics, daylighting from a side window requires shading to intercept direct sunlight from entering the window whilst allowing penetration of daylight from sky. Daylighting from a double-pane glazed window with enclosed horizontal slats has long been investigated under different climates and locations. In this paper, a double-pane window with the slats that were separated into two sections (lower and upper sections) was investigated for its daylight application in tropical climate. A series of full-scale experiments and simulations were conducted under real tropical skies and by which the slats in each section were tilted to different angles. Through the yearly simulations, performance of the two-section slat window was evaluated in terms of "useful daylight illuminance" (UDI), average interior daylight illuminance (ADI), and reduced light power density (LPD) of a dimmable lighting system. The results show that the two-section slat window can enhance the daylight use in the building by increasing more useful daylight illuminance, and providing better uniformity of the interior daylight distribution than the single-section slat window.

title: Longan drying using microwave-hot air and microwave-vacuum

description: Dried longan Thai economic product with an export revenue of 4,026.3 million baht in 2013, is traditionally produced by a hot air drying method, which takes more drying times and deteriorates qualities of the dried product. To improve the qualities of dried longan, alternative drying techniques, i.e. microwave combined with hot air (MHD) and microwave under vacuum pressure (MVD) were proposed in this study. Longans (Dor variety) were dried from the initial moisture content of 360-400% (d.b.) to the intermediate moisture content of 70% (d.b.) with MHD and MVD, and then further dried by only hot air to the final moisture content of 20% (d.b.) Temperature of hot air with velocity of 0.3 m/s and recycled air of 80% was set at 65 ? C and vacuum pressure was set at10 kPa. The effect of microwave power at 100, 125 and 150 W on longan drying kinetics and qualities of dried longan in terms of color as well as drying energy were studied. Comparison to hot air drying, it was found that the MHD and MVD reduced drying time and specific energy consumption as well as produced dried longan with less redness and yellowness but more lightness.

title: Electricity saving potential and carbon dioxide emission reduction in PVC industry in Thailand

description: It was reported that petrochemical sector in Thailand consumes 15% to 17% of the total industrial sector's energy consumption. Plastic resin industry in Thailand is one of the downstream sub-sectors of the petrochemical sector, which shares approximately 21% of the energy use of the sector. It is important for the industry to encourage the efficient energy management initiatives in order to minimize the energy cost and to maximize the benefit. In addition to the gain of energy conservation and higher energy efficiency, this will enhance the capability of the industry to compete with the same industry in the global scale. The objective of this research is to analyze the energy efficiency by evaluating the specific energy consumption (SEC) and the energy saving potential of the polyvinyl chloride (PVC) resin industry in Thailand. The analysis consists of four steps. First, the 2013 baseline for energy and material use in PVC resin industry is established. Secondly, the characterization of energy-efficient technologies to improve energy efficiency is discussed, and the potential applications and impacts of these measures are determined.  In addition, scaling up the saving energy from each measure and constructing conservation supply curve (CSC) to assess the economic potential for energy efficiency improvement in Thai PVC resin industry are performed. The result shows that the total technical and the cost effective (economic potential) of electricity-efficiency potential for the Thai PVC resin industry in 2013 is estimated to be about 25,355 and 16,625 megawatt-hours (MWh) respectively. Moreover, the economic potential and the total technical of carbon dioxide emission reduction are 10,654 and 6,986 tCO2, respectively.

title: Rationale for studying encouragement of energy efficiency amongst new modern energy consumers in the Mekong region

description: Energy efficiency improvements offer multiple benefits, such as reduced household energy expenditure and improved productivity, thus contributing to economic growth. Energy efficiency (EE) also results in reduction in greenhouse gas (GHG) emissions and enhanced energy security. For developing countries, EE could make modern energy services available at a faster pace and at lower costs to those who currently lack access to electricity. New modern energy consumers, i.e. those who are connected to the electricity grid with daily incomes of US$ 2 to 5, are expected to account for a large share of the expected increase in energy demand and thus GHG emissions in the Greater Mekong Sub-region (also known as GMS: Cambodia, Laos, Myanmar, Thailand, and Vietnam). However, this target group does not exist in OECD countries and for that reason there are few examples of EE policies that can be replicated and/ or adapted to the GMS. Furthermore, effective implementation of energy policies remains a key challenge in GMS and other countries of the developing world. This paper describes the rationale for research that will investigate EE amongst "New Modern Energy Consumers" in the Greater Mekong Sub-region in order to improve policy design and implementation of EE measures.

title: WIND TUNNEL TEST FOR CALCULATING WIND FORCES ON SCAFFOLDS WITH BASEBOARD HEIGHT AS A PARAMETER

description: The Japanese Industrial Safety and Health Law was revised in March 2009 to introduce new measures concerning accidental falls in the construction industry. This revision mandates the use of guard rails, handrails, and other scaffold components. The wind load criteria and structural specifications of scaffolds are regulated by current design codes. Nevertheless, these provisions do not necessarily comply with the newly incorporated legal requirements because they apply to old-style scaffolds. This study examined the wind force on scaffolds by wind tunnel test, with baseboard height used as a parameter. The wind force coefficient of one story of scaffolds was calculated. Wind force coefficient increased as baseboard height increased. The wind force on the scaffolds equipped with baseboards is 9.2 times that on the scaffolds without baseboards. The baseboard must be greater than or equal to 15 cm to satisfy regulation requirements. The wind force coefficient of scaffolds with a 15 cm baseboard is 1.5 times that of the scaffolds without a baseboard. In scaffold design, baseboard height should be considered to guarantee a suitable wind force coefficient.

title: Efficient electrical home appliance supply chain for low income household in Thailand

description: Energy efficient (EE) household appliances are considered as one of important players to reduce energy consumption in the residential sector. Price and accessibility of EE appliances are still a crucial concern for low income household in Thailand. While there are several energy efficiency policies for producers and end-users, only few polices for retailers and wholesalers have been implemented in Thailand. A gap of EE distribution to low income household can partially be caused because of a lack of EE policy addressing the supply chain. Energy efficiency policy could focus more on retailer and wholesaler shops by introducing financial support and knowledge training. Providing business network and simplified information on EE to retailers could also help spreading out the benefit of using EE products directly to endusers. Policy integration of enforcement Minimum Energy Performance (MEP) and Standard Offer Program (SOP) for retailers and wholesalers could contribute to the EE supply chain improvement in the future.

title: A survey of housing features and thermal comfort of medium and low income earners in Thailand

description: House design is influenced by the climate and the culture of people at a location. Thailand is located in tropical climate with low wind velocity and ambient air is humid .Climate of each region is different due to their location. This paper aims to study typical house design of low and medium income in rural area of each region of Thailand including interviewing and measuring parameters required for thermal comfort assessment. Each houses type features are showed and analyzed comparing with living style, climate and tradition of people in each region. Thermal environment and comfort are also recorded and calculated for each region. Results indicate that typical houses features of low and middle income earners of each region are different up to their life style, climate and traditional. Neutral temperature of each region is also different. People in the southern feel comfort under higher operative temperature than other regions. And neutral temperature of Thai people is different from PMV assessment scale.

title: Reducing energy consumption cost and greenhouse gas emission for tropical low-income housing: Thailand contribution

description: Recently, there is insufficient effort and insufficient body of studies into the issues of low-energy housing for low-income and medium income earners. Even fewer studies have touched on the issue of thermal comfort for low-income housing.  Modern housing design does not adequately attempt to utilize daylight fully nor to provide sufficient but energy-efficient electric lighting during night time. This project is carrying out to study on reducing energy consumption cost and greenhouse gas emission for tropical low-income housing in Thailand. Recent progress is on the survey process in lowincome housing to collect the data of electric appliances, building configurations and energy uses in household, and establish the baseline for each household type in low-income housing in Thailand.
