摘要

城市区域建筑的震害预测有着重要的意义。本文采用城市抗震动力弹塑性分析方法,基于唐山市现有的城市建筑数据,对唐山市23万多栋建筑进行了震害预测,从建筑设防分类、建造年代的角度对震害结果进行了分析。得到如下结论:①唐山市目前建筑抗倒塌能力有了显著提高;②非设防的老旧房屋是城市抗震的薄弱环节,应对非设防的老旧房屋进行加固改建;③提高城市的抗震"韧性"极为重要。本文的分析方法和结论可以为区域建筑震害模拟提供参考。
It is of great significance to simulate the seismic damage of buildings in urban areas.Using the nonlinear time-history analysis of urban buildings,a seismic damage simulation for 230000 buildings in central Tangshan City are performed using the current urban buildings data of Tangshan.The following conclusions can be drawn:I.The building seismic resistance of Tangshan City has been remarkably improved over the past 4 decades;II.Old non-engineered buildings have very low seismic resistance,which should be enhanced by retrofitting as soon as possible.III.It is of great importance to improve the seismic resilience of urban cities.The outcomes of this work are expected to provide a useful reference for future works on urban seismic loss estimation of buildings.
