摘　　要：对1985年墨西哥城大地震中受损的一幢10层钢筋混凝土框架-剪力墙结构楼房建立起空间三维杆系分析模型,并在弹塑性滞回模型中考虑了钢筋混凝土构件的退化特性,输入结构原型附近场地实际加速度记录进行三维时程分析,通过与1/10比例钢筋混凝土整体模型的三维振动台试验数据进行对比,验证了采用的弹塑性时程分析工具和振动台试验技术的有效性,讨论了其中需要进一步研究解决的问题。The three - dimensional spatial rod system analysis model for a ten storyed reinforced concrete building, which was damaged in the 1985 Mexico major earthquake, considering the deteriorative character of reinforced concrete member in inelastic hysteresis model is established. The actual acceleration record of the near site of building is inputted to cany out the three dimensional time - history analysis. By comparing the calculating results and the three dimensional shaking table data of a 1/10 scale reinforced concrete integral model, the validity of both the used inelastic dynamic analysis method and the shaking table test technique in simulating actual seismic response are evaluated, some problems which need to be further researched are also discussed.
