摘要
索杆张力结构是指由张力索和压杆组成的、具有预应力自平衡的新颖结构体系。初始预应力分布的计算是索杆张力结构受力分析的基础。本文在讨论索杆张力结构体系特性的基础上，从平衡方程出发，应用矩阵奇异值分解方法和广义逆矩阵，计算确定索杆张力结构的初始预应力分布。算例表明本文的分析方法是正确和有效的。
The cable- strut tensile structures are the prestress equilibrium systems composed by tensional cables and struts. The calculating of initial prestress is basic and important for analyzing of cable- strut tensile structures. In this paper, the characteristics of the cable- strut tensile structures have been presented. The methods of calculating initial prestress which make use of the singular value decomposition and the generalized reverse matrix was given. Numerical examples show that the methods of this paper is accurate and effective.
