Research Review on Optimal Design of Semi-Rigid Steel Frames
Steel frame is an excellent structural form,the traditional design of steel frame generally simplifies the beam-column connection into two ideal extremes,i.e.,complete rigid connection or ideal hinge connection.However,the connection actually has obvious semi-rigid deformation characteristics.At the same time,structural optimization is the eternal goal of the engineering community.How to obtain an optimization scheme that is safe,reliable,and economical is a very important research topic in structural design.This paper reviews the research progress of the optimal design of semi-rigid steel frames,and summarizes the feasible measures of the predecessors,aiming to provide some reference for subsequent research.
