在“同一场地上相似的两幢建筑物，未来具有相似的震害程度”的假设前提下，提出了如何利用一个地区的部分建筑物单体的震害预测结果，对这一地区的其它建筑物单体的震害进行预测的方法，并从结构抗震角度研究了如何用加权Ｈａｍ－ｍｉｎｇ距离度量两幢建筑物的相似程度。 Under the premise of “two similar buildings on the same site with similar degree of earthquake damage in the future”, this paper proposes how to make use of the earthquake damage prediction results of some buildings in one area and estimate the other buildings in this area The method of predicting the seismic damage of a single entity is studied and how the degree of similarity between two buildings is measured by the weighted Hamming distance is studied from the view of structural seismic behavior.
