摘要
文章结合工程实例,介绍运用平面杆系法和空间梁格法分别进行建模计算的方法,分析结构在自重、预应力等恒载作用下剪力滞效应分布的特点,讨论了目前工程中常用的有效分布宽度法的不足,并提出了相应的修改意见。
Combi ned with construction practice, the arti cle i ntrod uces the model building calculation method by using plane linkage method and space grillage method.It analyzes the structure characteristics of the shear lag coefficient under self weight and pre-stress.lt also discusses the insufficiency of effective distribution width that is commonly used in current construction project,and proposes corresponding suggestions.
