城市一般建筑物震害预测

Earthquake Disaster Prediction for City Common Buildings

论文对已有城市一般建筑物震害类比法进行了改进,主要包括对不同结构类型考虑5个不同的影响因素,通过灰色关联度确定权重。与已有方法相比,该方法更符合已有的震害经验。最后基于改进的震害类比法编写一套面向对象的可视化程序,该程序将城市的一般建筑分为多层砖砌体结构、钢筋混凝土框架结构、单层厂房和高层结构4类结构,并建立相应的数据库,可迅速,方便,简单地预测城市一般建筑物的震害。

In this paper an improved earthquake damage analogue prediction method was introduced which selected five different factors to four different structure types, and get more logical weight by grey relation analysis. This new method is more objective than the old one. At last, an object - oriented visual earthquake damage prediction program was established which was based on the improved analogue prediction method. The system classified city common buildings as the muhistory masonry buildings, multistory frame structures, one-storey mill structure and high-rise buildings. It can predict city common buildings more simply, more quickly, more conveniently. The system will be used in the seismic loss prediction of earthquake disaster prevention plan of Wuhan city.
