半刚性钢框架优化设计研究综述

Research Review on Optimal Design of Semi-Rigid Steel Frames

钢框架作为一种优良的结构形式,传统设计中一般把梁柱连接简化为两个理想的极端,即完全刚接或者理想铰接,然而连接实际上具有明显的半刚性变形特性。同时,结构优化是工程界永恒追求的目标,如何得到既安全可靠,又经济节约的优化方案,是结构设计中非常重要的研究课题。本文梳理了半刚性钢框架优化设计的研究进展,总结前人的可行之处,以期为后续的研究提供一定的参考。

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.
