本文根据我国高层建筑的特点及试验和实测结果,比较系统地研究了抗震计算的实用方法。主要分三个部分:一是自由振动计算的方法(第一、二、三节);二是自振周期的实测结果及统计分析(第四节);三是地震荷载问题(第五节)。 Based on the characteristics of high-rise buildings in China and the results of experiments and measurements, this paper systematically studies the practical methods of seismic calculation. It is mainly divided into three parts: one is the method of free vibration calculation (first, second and third sections); the second is the actual measurement result and statistical analysis of the natural vibration period (Section 4); the third is the issue of seismic load (Section 5).
