摘　　要： 张弦梁结构由拱、撑杆和拉索组合而成,近年来在大跨度工程中得到了日益广泛的应用.其结构特点是索受拉、撑杆为受压二力杆、拱为压弯构件.本文结合已建实际工程,对一维张弦梁结构的拱和撑杆的稳定性能进行定性分析,并对风吸力作用下的稳定问题进行探讨,可供工程设计者参考. Beam string structure, composed of arches, struts and cables, has been widely used in largespan structures recently, in which cables are subjected to axial tension, struts are subjected to central compression and arches are beam-column members. In this paper, according to practical engineering, the stable behaviors of arches and struts in plane beam string structure have been analyzed qualitatively, as well as the stability under action of wind suction force. The conclusions obtained may be useful to designers.
