본 연구에서는 주기하중에 대하여 거시적 모델링 방법을 다르게 적용하여 철근콘크리트 벽체의 비선형 해석을 수행하고 기존에 나타난 실험 연구와 비교/분석하였다. ASCE41-06에서 제시하는 높이-길이 비에 따른 벽체의 파괴유형을 참고하여 기존에 수행된실험연구 중에서 높이-길이비가 3.0을 초과하는 세장한 벽체와 높이-길이비가 1.5인 낮은 벽체를 선택하였다. 각 실험체에 대하여 거시적모델을 다르게 고려하여 비선형 해석을 수행하였다. 본 연구에서 적용한 거시적 모델은 휨에 대한 거동을 정확히 묘사할 수 있는 방법과벽체의 복부에서 발생되는 대각 전단을 고려할 수 있는 방법이다. 세장한 벽체는 거시적 모델에 따른 실험과 해석의 결과 차이가 거의없는 것으로 나타났지만 낮은 벽체는 모델링 방법에서 고려할 수 있는 요소에 의해 이력 거동이 크게 달라지는 것으로 조사되었다. 또한,높이-길이 비가 1.5인 철근콘크리트 벽체가 건축물에 적용된 경우 정확한 횡 저항능력을 평가하기 위해서 복부의 대각 압축 전단을 고려할 수 있는 모델을 사용하는 것이 타당하다.

In this paper, the tensile stiffness and deformation of laminated rubber bearing is investigated based on the research and test results. ISO 22762 and JIS K 6410 are not providing the tensile characteristics of rubber bearings. Besides, the tensile stiffness and deformation models are proposed by several researchers by quite different methods. Proper models are recommended for nonlinear deformation state in order to propose the tensile model and build up base data.

Development of appropriate construction technology at frozen soil environments for developing resources is essential. However, cathodic protection technology using monitoring at frozen soil environments is lack. In this study, we want to build a real-time monitoring system at frozen soil environments through corrosion monitoring using type of gavanic metal

Shows the problem of exposure to vibration generated from vehicle and train adjacent to the railway facilities are housing facilities. As a method for solving the problems caused by the vibration countermeasures have been provided various methods such as the vibration of the vibration trajectory, wave barriers wall, vibration isolation mat. Therefore, in the present study is to evaluate the vibration analysis by using vibration isolation mat for vibration reduction of housing facilities.

Typically low-rise dormitory designed bearing wall system. So, insulated concrete sandwich panel for the application of a rigid frame structure was changed. This study presents field application of insulated concrete sandwich panel through applying Test-Bed.

This paper describes an experimental program to investigate the shear behavior of insulated concrete sandwich panels (CSPs) with different types of GFRP shear connector. The study included testing of 13 insulated CSP specimens with two types of surface conditions for extruded polystyrene (XPS) insulation and various shapes of shear connectors. All specimens were loaded in direct shear by means of push-out and were consist of three concrete panels, two insulation layer and four rows of GFRP shear connectors. Load-relative slip between concrete panel and insulation response of CSP specimens has been established through push-out shear test. Test results indicate that the surface condition of insulation has a significant effect on the bond strength between concrete panel and insulation. The specimen used XPS foam with 10mm deep slot shows higher bond strength than those used XPS foam with meshed surface. Corrugated GFRP shear connectors show equivalent strength to grid GFRP shear connectors. Cross-sectional area and embedded length of shear connector have a notable effect on overall response and inplane shear strength of the CSP specimens.

This paper analyzed the CO2 emission of existing buildings with reconstruction and reusing in declined commercial area of Jeonju old town. The average CO2 emission to square meter of commercial buildings in Junju is 1.4tCO2/m2.

This study is to evaluate performance of two-way acting insulated sandwich wall panels through flexural experiment. The two-way acting panel resists wind loading on the panel and on the window. In this study, GFRP(Glass Fiber-Reinforced Polymer) Grid-type shear connectors are used for the composite action of the sandwich wall panels. Layouts of shear connector are considered as main parameter of this experimental study.

This study is to evaluate fatigue resisting capacity of insulated sandwich wall panel under wind-induced fatigue loading. The fatigue loading is calculated based on the probability distribution function (Weilbull and Rayleigh). The serviceability of the insulated sandwich panel was evaluated subjected to the probability-based fatigue loading.
