摘要
本文讲述了力对冲效应在结构设计中的模拟应用,该应用充分利用大框架体系中桁架叠加形成对冲,对其叠合桁架之间共用的弦杆会同时出现拉力和压力,由于力对冲作用弦杆的受力会变小,达到结构体系承载力高、刚度大、动力性能好、材料用料少、施工周期短等优良标准。
This paper describes the simulation application of force hedging effect in structural design.This application makes full use of the superposition of trusses in a large frame system to form hedging.The chords shared by the superimposed trusses will appear both tension and compression.Due to the force hedging effect,the force of the chord will become smaller,reaching the excellent standards of high bearing capacity,high rigidity,good dynamic performance,less material and short construction period of the structural system.
