摘要
在总结和比较了国内外标准中对装配式混凝土结构施工验算规定的基础上,根据《工程结构可靠性设计统一标准》GB50153—2008的有关规定,在《混凝土结构工程施工规范》GB50666—2011中提出了装配式混凝土结构施工验算规定。讨论了施工规范GB50666—2011中预制构件制作、预制构件运输与堆放、预制构件安装与连接等不同阶段的荷载取值、计算模型以及预制构件、临时支撑、预埋吊件的验算方法和验算要求等规定。通过算例说明了有关规定的应用。
A summary and comparison on design of precast concrete structures during construction specified in different standards are presented.Based on Unified standard for reliability design for engineering structures GB50153—2008,the specifications on checking calculation of precast concrete structures during different construction stages are proposed in Code for construction of concrete structures GB50666—2011.The load values,calculation models,the checking method and requirements for precast member,temporary bracing,handling insert,and so on,during production,handling,storage,transportation and erection are discussed.Some calculation examples are given to explain the application of the code GB50666—2011.
