摘要
张弦梁结构是由下弦拉索、刚型撑杆、上弦抗弯受压构件组合形成的一种自平衡结构体系。张弦梁结构在我国发展迅速,该结构具有跨度大、自重小、施工便捷等优点。本文介绍了张弦梁结构的起源与概念,从上弦梁的截面特性、撑杆数量、垂跨比、预应力取值四个方面总结了张弦梁结构的静力性能,并对张弦梁结构的自振特性研究进行了分析总结,以期促进张弦梁结构在工程中的广泛应用。
Beam string structure is a self-balancing structure system formed by the combination of cable,rigid brace and arch.Beam string structure is developing rapidly in China,which has the advantages of large span,small dead weight and convenient construction.This paper introduces the origin and concept of beam string structure,summarizes the static performance of beam string structure from four aspects of cross-section characteristics of upper chord-supported beam,number of braces,sag-to-span ratio and value of prestress,and analyzes and summarizes the research on natural vibration characteristics of beam string structure,in order to promote the wide application of beam string structure in engineering.
