刚性-半刚性混合节点钢框架性能的初步研究

Preliminary Study on Performance of Rigid-Semirigid Jointed Steel Frame

基于钢框架ANSYS有限元模型,对刚性、半刚性节点钢框架和刚性-半刚性混合节点钢框架在静载和动载下的受力与变形进行了对比分析,得出:刚性-半刚性混合节点钢框架在风载作用下的侧移量较接近于刚性框架;在地震作用下其各层的位移规律明显好于刚性框架,幅值介于刚性和半刚性框架之间,基本呈收敛状态.

Based on steel frame ANSYS model,this paper carried out compative analyses on the forces and deformations of rigid,semi-rigid and rigid-semirigid jointed steel frames under static and dynamic loads.The results showed that the lateral displacements of rigid-semirigid jointed steel frame comparatively approached those of rigid steel frame under the wind-load effect,while the displacement laws of its all layers were obviously more superior than those of the rigid under the earthquake excitation,with the amplitudes lying between the rigid and the semi-rigid and basically presenting the convergence condition.
