Abstract

High-strength concrete has demonstrated characteristics of both increased strength and enhanced durability; hence its use has become more and more widespread. But, due to the lack of experimental evidance on the seismic performance of frame members constructed with high-strength concrete, the current codes of their design provisions are based on normal concrete test. The purpose of this study is to compare the response of the high-strength concrete beam-column-slab subassemblies with the response of a normal-strength concrete specimens. Four assemblies $(f_c'=240kg/\textrm{cm}^2, f_c'=700kg/\textrm{cm}^2)$ with 2/3 scale were designed and tested to investigate seismic behavior.

고강도 콘크리트는 부재의 내력증가 뿐만아니라 내구성을 증대시키기 때문에 널리 사용되고 있다 그러나 고강도 철근콘크리트 보-기둥 접합부의 구조성능에 관한 연구자료는 충분하지 않은 실정이며 현행규준 또는 일반강도 콘크리트의 실험에 근거하고 있다 따라서 본 연구에서는 일반강도 $(f_c'=240kg/\textrm{cm}^2) 및 고강도(f_c'=700kg/\textrm{cm}^2)$ 콘크리트를 사용하여 실제의 중진지역 30층 실제구조물의 2/3크기를 축소한 보와 기둥 슬래브로 구성된 네 개의 부분구조체를 제작하여 유사정적실험을 통한 구조거동과 파괴형태를 조사하고 전단내력에 대한 현행규준과 비교 검토하였다.
