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。
In recent years, with the promotion of precast concrete structures, precast concrete wall panels as an important component in the design is often used, the actual project often encountered in the middle due to the construction needs of large openings wall panels, which The design of the kind of wallboard under complicated stress conditions poses a challenge to the designers due to the obviously lagging behind of relevant specifications. Aiming at the key problems in the design of prefabricated concrete exterior wall panels with large open hole lines, a series of methods of load selection, analysis and design and seismic performance design of line support connections are put forward. And a concrete engineering example is given, Can provide reference for similar engineering design.
