摘要
多质点系剪切模型在多层平面框架的抗震分析中已得到了广泛的应用 ,但这种模型不能考虑梁柱的强度比和刚度比、节点域变形、附加轴力和梁塑性铰对地震响应的影响。本文介绍的鱼骨形模型既能考虑以上所有因素 ,又对平面框架进行了有效的简化 。
The conventional model which has been generally used for seismic response analysis is equivalent multi-particle shear vibration system,but this system can not take into account the strength and the stiffness beam-to-column ratio,the deformation of joint region,additional axial force and plastic hinge of the beam influence on seismic response.The fishbone-shaped frame model introduced in this paper not only consider the former factors but also simplify the multistory planar frame effectively.So it is well applied to the two-order elastic-plastic dynamic analysis of steel frame.
