摘　　要：本文提出了确定剪切刚度层模型恢复力特性骨架线的简化计算法。以北京国贸中心高层钢结构为例，用简化法和弹塑性荷载增量法计算了层恢复力特性骨架线，用这两种骨架线进行了弹塑性时程分析，两者的结果比较接近。简化法确定的骨架线适用于高层建筑钢结构在大震作用下的安全验算。In this paper, a simplified method for calculting the actoring-force characteristic skeleton curve of story shear stiffness model is presented Beijing lnternational Trade Center high-rise steel structure is taken as an example, both the simplified method and the elasto-plastic load increment method the are used to calculate its story restoring-force characteristic skeleton curves. Elasto-plastic time history analyses are carried out by using the curves obtained from these two methods. Results are approximately the same. It is recommended.that the simplified method is suitable to elasto-plastic time history analysis of hgh-rise steel structures.
