中文摘要：
为模拟钢框架结构的典型震害，本文基于ANSYS软件建立了钢框架结构简化模型。该模型可以考虑楼板对钢框架结构整体性能的影响，并且进一步考虑了楼板与钢梁之间的滑移、节点域变形，以及梁柱节点焊缝的断裂等因素。应用本文建立的钢框架结构模型对北岭地震中Blue Cross大厦的震害进行了模拟，与实际震害对比的结果表明，该模型能够比较精确地模拟地震作用下钢框架结构的响应。钢框架结构模型对节点焊缝断裂的钢框架结构震害研究有着重要的意义。
英文摘要：
The authors aim to simulate the typical seismic damage to steel frame structures. For this purpose ,an analytical approach was proposed for making the seismic evaluation of welded steel frame structures based on ANSYS computer program. The effect of slabs on the response of steel frame structures was investigated. Further more, the model considered the slip between slabs and steel beams model was employed in the simulation of seismic damag , deformation of panel Zone and connection fractures. The e to Blue Cross Building, the connections of which were fractured in the Northridge earthquake. Results from several analyses indicate that the model can accurately predict the earthquake responses. The approach proposed in this paper has important meaning in the research on the seismic damage to steel frame, the connections of which may be fractured
