【摘要】 对山东西北部某县农村建筑物进行了调查,具体分析了几种建筑的结构形式,并指出其存在的隐患。选取距离调查地区较近地震台站记录的天津波、El-Centro波和一条二类场地人造地震波,用有限元方法分析了该地区最常见最具前景建筑物的抗震性能。结果表明,即使是遭遇本地区基本设防烈度的地震作用,这种建筑物也存在因屋顶相对位移过大导致其倒塌的危险。根据该地区建筑物的特点,提出了相应的构造措施,并通过计算,分析了采取该抗震措施的有效性,还说明了提高我国农村民居抗震性能的紧迫性。更多还原

【Abstract】 Investigation was performed on one county’s rural buildings in northwest of Shandong province.The aseismic performance of buildings in this region was evaluated,with a detailed analysis of pitfalls of the structures.Choosing Tianjin wave,which is near the area,El-Centro wave and an item of artificial wave,the most common and prospective structures were analysed in this region through the finite-element method.The result shows that even under basic fortification intensity,the structures are in danger because of excessive relative deformation in the roof.According to the features of the building,the corresponding improvement measures were proposed,which were verified through calculation.It is urgent to improve rural dwellings seismic performance.更多还原
