진동대실험을 통한 비내진상세를 가지는 RC 골조의 조적채움벽 유무에 따른 동적 거동 평가

Abstract

In this paper, the shake table test for the masonry infilled reinforced concrete frame with non-seismic details was carried out in order to evaluateits dynamic behaviour and damage under seismic condition. The tested specimens were the RC frame and the masonry infilled RC frame and the dynamiccharacteristics, such as a resonant period, acceleration response, displacement response and base shear force response, were compared between them. As a result of the shake table test, RC frame specimen had flexural cracks at the top and bottom of the column and shear cracks at the joints. In thecase of masonry infilled RC frame, the damage of the frame was relatively minor but the sliding cracks and diagonal shear cracks on the masonry wallwere severe at the final excitation. The resonant period of infilled RC frame specimen was shorter than that of the RC frame specimen because the masonryinfill contributed to increase the stiffness. The maximum displacement response of the infilled RC frame specimen was decreased by about 20% thanthe RC frame specimen. It was analyzed that the masonry infill wall applied in this study contributed to increase the lateral strength of the RC framewith non - seismic detail by about 2.2 times and the stiffness by about 1.6 times.
