摘要:
根据地震作用下建筑物上部楼层倾倒时的破坏特点及理论分析，提出建筑物上部楼层倾倒时的倒塌模型。针对此模型进行受力分析及动力学分析，从而推导上部楼层倾倒模式下安全距离计算公式，并采用数据拟合的方法进行简化，得出建筑物倒塌破坏安全距离简化计算表，以便于震后应急道路有效宽度的规划控制。研究表明，简化公式值与理论值最大相对误差为4.38%，平均相对误差为0.76%，均在误差允许范围内。同时，推导出的理论公式与简化公式高度相关，相关系数为0.9999。研究结果可为实际地震中计算建筑物倒塌安全距离提供理论依据，可用于规划分析。
Abstract:
According to the destruction characteristics and theoretical analysis of upper structure toppling for buildings under earthquake, the collapse model of upper structure toppling for buildings was suggested. Based on force analysis and dynamic analysis on this model, the formula for safety distance of collapsed buildings was deduced, and the simplified formula was provided through data fitting method. In order to convenience the planning control on effective width of emergency road after earthquake, the simplified calculation table of safety distance of collapse buildings was provided. It showed that the maximum relative error between simplified formula value and theoretical value is 4.38% and the average relative error is 0.76%, which are within permission. At the same time, the correlation coefficient is 0.9999, which shows that the simplified formula is highly correlated with theoretical formula. So it can provide theoretical basis for the calculation of safety distance for collapsed buildings under practical earthquake, and it is available to planning control.
