Stress Impact Analysis of Steel Frame with Different Beam-Column Connection Mode

Gang Wang

Abstract

This paper uses the SAP2000 to establish different beam column connections of steel frame structure finite element model, comparative analysis of the beam column for the rigid connection, hinged, semi-rigid connections of steel frame structure, the dynamic characteristics of structure displacement and internal force influence. At the same time, the dynamic time-history analysis method for structural displacement supplementary checking, analysis of structural response to seismic wave degree．The results showed that：compared with rigid, the structure of semi-rigid connections to the larger natural period，and with the rotation stiffness decreases vibration period increases; Semi-rigid steel frame connection to reduce the resistance to push the layer stiffness，making the structure of the horizontal displacement increased．
