摘要
在区域建筑震害模拟中采用剪切层模型与弹塑性时程分析,既可以考虑结构的高阶振型和地震动的特性,又不会导致巨大的计算量。"清华校园建筑震害预测程序"使用这种方法,可对清华校园在给定地震动下进行建筑震害模拟,并直观地显示结构各层位移响应、各层破坏状态等震害模拟结果。使用普通个人计算机对619栋校园建筑进行震害模拟,总计算耗时仅有15秒。
The inter-story shear models and elasto-plastic time history analysis in the regional seismic damage simulation,not only can take account of the structural high modes and the characteristics of a certain ground motion,but also don't produce too much calculation workloads. Such method is applied to "Seismic damage prediction program for campus buildings in Tsinghua University",which can simulate the seismic damage of Tsinghua campus in the given ground motions and clearly display simulation results such as the structural response and damage states of each story. Besides,a regional seismic damage simulation for 619 buildings only costs 15 seconds by a common personal computer.
