Abstract

Safety and efficiency in the construction of RC structures mainly depends on optimal operation of shore-slat systems. The disasters in RC construction are mainly due to excessive load applied to falsework and premature removal of supports. Development of sufficient compressive strength of early-age connote is essential for the safety of structures during construction. Most of studies on shore-slab interaction have focused on flat slab structures. In this study, load distributions in floor slabs and supports during the construction of shear wall-type RC apartment building structures is investigated using finite element analysis.

철근콘크리트조 공사의 안전성과 효율성은 동바리-슬래브거푸집의 최적의 운영에 달려있다. 철근콘크리트공사에서의 사고는 주로 가설공사에 과도한 하중이 작용하였거나 동바리를 조기에 철거하기 때문에 발생한다. 콘크리트의 조기압축강도발현이 공사중구조체의 안전에 중요하다. 슬래브-동바리의 상호작용에 관한 연구는 주로 무량슬래브 구조에 대하여 이루어 졌다. 본 연구에서는 전단벽식 철근콘크리트조 아파트에서 슬래브와 동바리에서의 하중분포를 유한요소법을 이용하여 조사하였다.
