以淮南市作为研究对象,应用能力谱方法对淮南市建筑物在8度地震下的破坏情况及相关损失进行了计算。根据建筑物结构的类型、抗震设防级别、层数、建筑高度和建筑材料等查表得到相应参数,构造出建筑物能力曲线。通过查阅建筑物抗震设计规范构建淮南市建筑物的需求谱。依据能力曲线与需求谱交点所确定对应的谱位移计算出建筑物对应各个震害等级的超越概率。用相邻震害等级中相对轻的震害等级对应的超越概率减去相对重的震害等级对应的超越概率,得到建筑物处于各个震害等级的概率。并根据破坏的严重程度进行了震害区划。研究结果表明,淮南市的大部分地区在8度地震的情况下破坏并不十分严重,但区域12,13和17的破坏相比于其他区域较大,这些区域正是淮南市主要的老城区,存在大量的老旧建筑。研究结论与实际情况基本相符,具有较高的实用价值。
Taking Huainan city as the research object, the damage of buildings in Huainan city under 8-degree earthquake and the related loss were calculated by using the method of capacity spectrum. According to the type of building structure, seismic fortification level, number of floors, building height and building materials, such as table lookups to obtain the appropriate parameters to construct the building capacity curve. Construct the demand spectrum of buildings in Huainan by consulting the code of building aseismic design. Based on the spectral displacement determined by the intersection of capability curve and demand spectrum, the transcendence probability of each grade of earthquake damage corresponding to the building is calculated. The probability of the building being at the level of each earthquake damage is obtained by subtracting the excess probability corresponding to the relatively heavy earthquake damage level from the excess probability corresponding to the relatively light earthquake damage level in the adjacent earthquake damage classification. According to the severity of the damage damage zoning. The results show that most areas in Huainan City are not seriously damaged in the 8-degree earthquake, but the damage in areas 12, 13 and 17 is larger than that in other areas. These areas are the main old urban areas in Huainan , There are a lot of old buildings. The conclusions of the study are basically in line with the actual situation and have high practical value.
