阐述了一种综合的、虽然相对简单的钢筋混凝土建筑物地震损伤分析的非线性方法（N2法）。该方法的基本特点是：使用两个独立的数学模型，应用反应谱法和非线性静力分析，并选择一个损伤模型，其中包括累积损伤。该方法产生合理的精度提供的结构振荡主要在第一模式的结果。一个七层楼的建筑物的三个变种已被用作说明性的例子，该方法的应用。四种不同类型的分析，具有不同程度的复杂性，已经进行，以估计的影响，在N2方法中使用的几个假设和近似。
A comprehensive, though relatively simple, non-linear method for the seismic damage analysis of reinforced concrete buildings (the N2 method) has been elaborated. The basic features of the method are: the use of two separate mathematical models, application of the response spectrum approach and of the non-linear static analysis, and the choice of a damage model which includes cumulative damage. The method yields results of reasonable accuracy provided that the structure oscillates predominantly in the first mode. Three variants of a seven-storey building have been used as illustrative examples for the application of the method. Four different types of the analysis, with different degrees of sophistication, have been performed in order to estimate the influence of several assumptions and approximations used in the N2 method.
