Recently, Earthquake occurrence in korea has become frequent, and the seismic safety of low-rise piloti buildings becomes more and more important. In this study, the seismic retrofit method of low-rise eccentric core type piloti building structures using concrete filled steel tube (CFT) columns was analysed and verified for seismic performance.

To improve the wet process of concrete core wall, which is one of lateral load resisting system in high-rise modular building, the new composite panel system is developed and its structural performance under lateral load is investigated analytically.

In this study, the heat insulating performance increase the indoor temperature of the building is applied to the concrete was compared with plain concrete. As a result, the indoor surface at the outside temperature of 10.4 ~ 22.4 ℃ temperature conditions showed a difference of up to 0.6 ℃, the lowest 0.6 ℃, indoor temperature is up to 0.2 ℃, 0.2 ℃ lower results showed a minimum.

The purpose of this study is the evaluation of the seismic performance for the reinforced concrete piloti building considering special earthquake load. For this, nonlinear static push-over and dynamic seismic response analysis for the two models designed with and without special earthquake load were carried out.

The objectives of this research are to compute performance point using capacity spectrum analysis, and to use structural damage states classification and damage state criteria through interstory drift angle presented in HAZUS. Seismic fragility curve is drawn by seismic fragility parameter and predict damage probability about non seismic reinforced concrete buildings according to building shapes.

This is preliminary study for development of specialized seismic performance evaluation and reinforce guidelines for piloti-type buildings. A residential Building with Pilotis was selected and the seismic performance evaluation was performed. The vulnerable parts of the piloti-type building for earthquake and the risks are verified. Finally, the necessity of evaluation and reinforce guidelines for the building with pilotis is presented.

This paper presents a design process of columns in precast concrete frame building structure constructed by using hollowed precast concrete (HPC) column. An example PC frame building was designed and the structural safety of HPC columns was checked as a form for during slab construction and a composite column for design load after construction based on the previous research.

This study presents the seismic evaluation and prediction of post-retrofitted piloti-type reinforced concrete building with buckling-restrained braces (BRBs) under the successive earthquakes. For seismic assessment before and after retrofit of the BRBs, the fragility analysis is considered. The fragility relationships for the damaged building between ground shaking intensity and damage probability were derived under the successive earthquakes.
