基于门式刚架和预应力钢结构的研究成果,对全局布索预应力门式刚架进行了分析。根据结构的变形特征和受力机理,提出拉索参数确定准则,并依据该准则及简化计算模型,推导了结构在预应力及竖向荷载下的内力及变形的求解方程;最后,采用SAP2000建立典型算例,验证了理论求解方程,分析了理论解与数值模拟间的误差。为门式刚架全局快速布索的初步设计奠定了理论基础。

Based on the research of portal steel frame and pre-stressed steel structure,cable-supported and knee-braced steel frame is analyzed. According to the structural deformation characteristics and stress mechanism,the determination rules for cable's parameters are presented. Based on the rules and simplified calculation model, the equations of internal force and deformation under pre-stress and the vertical load are established;finally, with SAP2000 we give typical examples to verify the theoretical equation,and discuss the cause of error. The theory is useful for preliminary design of the cable to be set up quickly in the portal steel frame.
