摘要
针对幕墙索杆桁架设计计算中的若干问题 ,进行了分析研究 ,提出了索杆桁架体系初始状态预应力分布确定的最小二乘法 ,推导了只拉单元和连续索单元的数值模型 ,讨论了索杆桁架支撑体系的稳定性。
In this paper, studies are made on some designing and computing problems of tension\|rod & truss supported glass curtain. The least square method is used to decide the initial prestress distributions in tension\|rod & truss supported glass curtain, and the numerical models of tension\|only element and continuous cable are deduced, at the same time, the stability of tension\|rod & truss support system is discussed.
