摘要
近年来,我国城镇化建设速度不断加快,发生破坏性地震所造成的损失也更加难以承受。只有通过合适的震害预测方法,才能对城市的抗震能力做出准确的评价,得到有效且针对性强的预防对策,进而提高城市综合抗震防灾的能力。本文基于半理论半经验方法,运用新的群体建筑物层间现有受剪承载力计算公式,对1座北方城市的框架结构建筑物进行了震害预测,得到了该城市框架结构的易损性矩阵,并通过划分年代详细分析了不同建造时期建筑物的震害预测情况,为该城市的抗震防灾规划提供了数据支撑。
In recent years,the speed of urbanization in China has been accelerating,and the losses caused by destructive earthquakes are even more unbearable.Only through appropriate earthquake disaster prediction methods can the city s seismic capacity be accurately evaluated,and effective and targeted preventive measures can be obtained to improve the city s comprehensive capacity for earthquake and disaster prevention.Based on the semi-theoretical and semi-empirical method,this paper uses the new calculation formula of the existing shear capacity of the group buildings to predict the damage of the frame structure of a northern city,and obtains the vulnerability of the frame structure of the city.Matrix,and detailed analysis of seismic disaster prediction of buildings in different construction periods by dividing the age,providing data support for the city s earthquake disaster prevention planning.
