某综合楼框架梁质量事故分析

A Frame Beam Quality Accident in an Office Building;Analysis and Condusion

通过对某综合楼的质量事故分析 ,指出板与梁为不完全弹性连接 ,大跨度板拆模时间的瞬时 (动态 )挠曲对支承梁的影响非常大。提出在采用平面框架结构设计中 。

Based on the analysis results of a quality accident in an office building, it is concluded that the turning effect of floorslab to beam must be taken into account in plane girder design.Imcomplete elastic connection is between floorslab and beam.The influence is very large for beam when large span floorslab is instantaneous deflection in removing model slab.
