摘要
近年来,随着预制混凝土结构的推广,预制混凝土外挂墙板作为一种重要部件,在设计中经常被采用,实际工程中经常遇到由于建筑需要而在中部开设较大洞口的墙板,这种墙板在复杂受力工况下的设计,由于相关规范明显滞后而给设计人员提出了挑战。针对大开洞线支承式预制混凝土外挂墙板设计中的关键问题进行系统研究,提出了荷载选取、分析设计以及线支承连接的抗震性能设计的一系列方法,并给出了一个具体工程实例,可为类似工程设计提供参考。
During the recent years,with the wide application of precast concrete（ PC） structure,PC wall panels,as one of the key members,have been usually used in structural design. However,large opening in the middle of precast concrete wall panels due to architectural needs usually occurs in the actual project. Because the current code for this type of PC wall panels is lagging behind,this PC wall panels design under complicated load cases puts forward challenges to designers. The systematic research of the key issues in design for large opening line bearing precast concrete wall panels was carried out,and a series of method,including load selection,analysis and performance-based seismic design of line bearing connection were proposed. And an example of a project was given,which can be a beneficial reference for the similar project design.
