装配式高层钢结构中半刚性连接性能分析

Analysis of Semi-rigid Connection Performance in Prefabricated High-rise Steel Structure

文中以两种新型半刚性连接的预制钢结构为研究对象,评估预应力索和壁板对预制钢结构的影响,采用半刚性连接试验对结构构件的转动性能进行了评价,并采用所提出的优化程序对结构构件的初始截面进行了优化。结果表明,半刚性连接对装配式高层结构的抗弯性能影响显著,钢框架的刚度比模块化结构的刚度更显著。该方法可为钢结构模块化设计规范提供理论补充。

This study takes two new types of semi-rigid connection,evaluates the influence of prestressed cable and wall plate on prefabricated steel structure,evaluates the rotational performance of the structural members by the semi-rigid connection test,and optimizes the initial section of the structural members by the proposed optimization procedure.It is concluded that the semi-rigid connection has a significant impact on the bending performance of the prefabricated high-rise structure,and the stiffness of the steel frame is more significant than that of the modular structure.In addition,this method provides a theoretical supplement to the modular design specification of the steel structure.
