简要描述了张弦梁结构的概念,主要结构类型、发展途径以及张弦梁结构的主要特点。介绍了几个张弦梁应用实例,着重探讨了张弦梁结构在大跨径桥梁的非落地支撑系统中的应用,并通过一个具体工程结构设计,分析计算了张弦梁结构支撑系统的位移和内力,对张弦梁结构在桥梁工程中的应用作出有益的探讨。 The paper briefly describes the concept of the beam string structure, the main types of structures, the ways of development and the main features of the beam string structure. The application of several string beams is introduced. The application of the beam string structure to the non-landing support system of long-span bridges is emphatically discussed. The displacement and internal forces of the beam string support system are analyzed and calculated through a concrete engineering structure. In the bridge engineering application to make a useful discussion.
