本文介绍了目前中小学砖混结构教学楼的一些特点,地震易损性的原理,计算方法等。通过超越强度倍率,建立了地震易损指数与设计基本地震加速度的关系,从而建立了能够比较快速评定此类建筑的地震易损性方法。并通过一个实例说明了此方法的可行性。 This article introduces some characteristics of the brick and mortar structure teaching building in primary and middle schools, the principle of earthquake vulnerability and the calculation method. The relationship between the seismic vulnerability index and the designed basic seismic acceleration was established by exceeding the strength ratio, and a method to evaluate the seismic vulnerability of such buildings quickly was established. An example is given to illustrate the feasibility of this method.
