摘要
基于节点域是钢框架体系中的薄弱环节,介绍了节点域厚度和节点域刚度的关系,并以美国抗震规范和我国规范对节点域厚度公式进行了比较分析,探讨了节点域厚度的变化对高层框架层位移和层间位移的影响,指出适中的节点域变形对提高梁柱连接的延性有很大作用。
Joint panel zone is weak part in steel frame structure. In the paper the relationship between the thickness and rigidity of joint panel zone is introduced. Based upon comparison of the calculation formula of the thickness of joint panel zone in American and Chinese codes for seismic design the changes of the thickness of joint panel zone on level displacement and inter-story displacement of high-rise frame structure are discussed. Author points out the proper deformation of joint panel zone are good to increase the connection ductility of beam-column.
