Seismic performance of ordinary reinforced concrete shear wall systems commonly used in high-rise residential buildings is evaluated. Three types of shear walls exceeding 60m in height are designed by performance-based seismic design. Then, incremental dynamic analysis is performed collapse probabil...

건축구조기준(KBC2016)에서는 건축물의 높이가 60 m 이상이고 내진설계범주가 D에 해당하는 철근콘크리트 전단벽 구조시스템인 경우 전단 벽으로 무엇을 설계하도록 정의하는가? | 최근 국내 공동주택은 고층의 전단벽식 구조시스템을 흔히 사용하고 있으나 건축구조기준(KBC2016)에서는 건축물의 높이가 60 m 이상이고 내진설계범주가 D에 해당하는 철근콘크리트 전단벽 구조시스템인 경우 전단 벽을 보통전단벽이 아닌 특수전단벽으로 설계하도록 정의하고 있다. 특수전단벽은 규정에 따라 전단벽 단부에 경계요소를 설치하여야 하며 엄격한 배근상세를 요구한다. | |
2016년 개정된 건축구조기준(KBC2016)에 도입된 성능기반 내진설계는 무엇을 말하는가? | 2016년 개정된 건축구조기준(KBC2016)에 도입된 성능기반 내진설계는 기존 설계기준의 설계 계수와 방법의 적용가능 여부가 불확실한 경우 구조물에 대한 비선형해석을 수행하여 상세한 분석을 통해 구조물에 요구되는 구체적인 성능에 맞추어 구조물을 설계하는 방법을 말한다[1]. 구조물이 목표성능수준을 만족하는 경우 설계가 완료되나 성능을 만족하지 못하는 경우 반복적인 설계수정을 수행하여야 한다. | |
전단벽 설계에 있어서 특수전단벽이 시공성 및 경제성에 부정적인 영향을 끼치는 이유는 무엇인가? | 최근 국내 공동주택은 고층의 전단벽식 구조시스템을 흔히 사용하고 있으나 건축구조기준(KBC2016)에서는 건축물의 높이가 60 m 이상이고 내진설계범주가 D에 해당하는 철근콘크리트 전단벽 구조시스템인 경우 전단 벽을 보통전단벽이 아닌 특수전단벽으로 설계하도록 정의하고 있다. 특수전단벽은 규정에 따라 전단벽 단부에 경계요소를 설치하여야 하며 엄격한 배근상세를 요구한다. 따라서 전단벽 설계에 있어서 특수전단벽은 시공성 및 경제성에 부정적인 영향을 가지고 있다. |
