摘要
Abstract
In this article,the features of forces applied on steel tubular scaffolds with couplers which have greater aspect ratio are researched.The linear spring lattice column computing model is established with a special semi-rigid connection that spring elements are used to replace right-angle couplers and by introducing the telescopic coefficient and rotating rigidity of the spring unit.Under a unit horizontal force,the relative displacement between two layers is calculated with semi-rigidly connected steel frame model,and,the formula is deduced for calculating the buckling loads of this model.And,the modeling is made for value analysis to attain the values of buckling loads with MIDAS GEN finite elements software based on steel tubular scaffolds with couplers with an aspect ratio of 27.3.By comparison to the results of the simplified calculation,the calculating accuracy of the formula may meet the needs of engineering design and verification.关键词
