半刚性连接钢框架静力分析的精细传递矩阵法
Precise transfer matrix method for static analysis of steel frame with semi-rigid connection
摘要
Abstract
Aiming at the problem that the steel frame with semi-rigid connection has certain influence on the force behavior of structures,the precise transfer matrix method was utilized to perform the static analysis on the steel frame.The moment-rotation behavior of beam-to-column joints with semi-rigid connection was simulated with a three-parameter mechanical model,and the semi-rigidity of the joint connection was simulated with helical springs.According to the principle of precise transfer matrix method and the equilibrium differential equation of structures,the precise transfer matrix for the static analysis on the steel frame with semi-rigid connection was derived.In addition,the corresponding calculation program was compiled,and some example calculation was carried out.The calculated results indicate that the proposed method is correct and efficient,and can be used for the initial design and final check-up of structures.The semi-rigidity of beam-to-column connection will make the internal force of structures redistribute.During the analysis or design of steel frame structures,the influence of semi-rigid connection should be considered.关键词
