| 摘 要： | 以一个６层砖结构和四种场地共同组建成四个结构－地基一体化计算模型，输入唐山地震基岩地表的余震记录，计算融土场地、有冻层场地和刚性地基三种情况下结构的地震反应，通过结构基底等效输入和结构地震反应内力的比较，作者认为，对绝大多数中软场地，用现行的刚性地基假设，作多层砖房震害预测是偏于安全的。

| Abstract: | Four computational modeles are constructed of a 6-storeyed brick building based on four different sites into a single whole, respectively. An aftershock record of the Tangshan earthquake at the surface of the base rock is the input seismic motion when computing the seismic responses of the structure on following sites: rigid foundation, with or without the frozen layer. It seems certain that the method of damage prediction for multi-storeyed brick building based on the assumption of rigid foundation for most sites with soft soil layer is on the safe side. |
