가설구조물의 붕괴재해에 관한 연구
A Study on the Collapse Accidents of the Temporary Structures
초록
Formwork is a temporary structure that supports its own weight and that of the freshly placed concrete as well as construction live loads including materials, equipments, and workmen. In designing and building formwork, the contractor should plan for economical construction without sacrificing quality or safety. But these temporary structures sometimes collapse during the concrete placing. Among the accidents and failures that occur during concrete construction, many are formwork failures, which usually happen at the time concrete is being placed. Generally some unexpected events cause one member to give way, then others become overloaded or misaligned and the whole formwork structure collapses. In this study, formwork failure events from 1994 to 1997 are analyzed using the structural analysis program. So the causes of the respective formwork failure are explored. Therefore, the present study provides a firm base to design the temporary structures such as formwork.
