地震是由于地面的运动,使地面上原来处于静止的建筑物受到动力作用而产生强迫振动,因而在结构中产生内力、变形和位移。经过简化后模型的动力学分析,即一次次的震害分析进行修正、补充,得到一些建筑物在地震作用下的反应机理及破坏形式,提出了一些建筑物抗争的计算方法及设计的基本原则。这些在实际应用中得到了很不错的效果。
Earthquakes are caused by the movement of the ground, which force the original static buildings on the ground to generate forced vibration, thus generating internal forces, deformations and displacements in the structure. After simplification, the dynamic analysis of the model, that is, the analysis of earthquake damage again and again to amend, supplement, get some of the earthquake response of buildings under the action mechanism and form of destruction, some of the calculation methods of building resistance and design of the basic principles . These have been very good results in practical applications.
