摘　　要：大跨度空间张弦梁结构是通过撑杆连接抗弯构件和抗拉构件,并通过在抗拉构件上施加预应力而形成的一种自平衡体系。系统地研究撑杆数量、垂跨比、高跨比和预应力等参数变化对单向张弦梁结构位移和内力的影响,从而完成了单向张弦梁结构的荷载态优化。The long-span beam string structure （BSS） is a self-equilibrium system which uses bar to connect bending resistance member and tension member and imposes pre-stress on tension member.In this paper, the effects of the number of bars,sag-span ratio, rise span ratio and pre-stress of the string on the mechanics performance and displacement of single-direction BSS are studied systemically in detail. Finally, the form in loading equilibrium state of single-direction BSS is optimized.
