摘　　要：对城市中现有数量巨大的一般建筑的抗震能力进行评价,必须采用简便、实用的建筑物群体震害预测方法,才能在有限的时间内完成城市建筑物的震害预测工作。为此本文提出了基于支持向量机的建筑物群体震害预测方法,详细说明了基于支持向量机进行建筑物震害预测的步骤和方法。同时,本文利用建立的基于支持向量机的震害预测模型,对3栋现有建筑进行了震害预测,并将预测结果与单体震害预测结果进行了对比。研究结果表明,基于支持向量机的建筑物震害预测方法是一种可以用于建筑物群体震害预测的良好方法。In order to accomplish the earthquake damage prediction of massive ordinary constructions in a limited time, some simple but useful predictive methods must be used. The method of earthquake damage prediction of city buildings based on support vector machine is put forward and the procedures of this method are explained in details. Meanwhile, with the model which is established in this way, the earthquake damage predictions of three existing buildings are carried out as well as the comparison between this result and that of the single seismic damage prediction. The research shows that the earthquake damage prediction of buildings based on support vector machine is a good method which can be used to predict damage of buildings.
