建筑物的抗震设防需要地震动的输入,但往往在抗震设防区缺少地震记录,这就需要地震动的模拟.在总结现有经验格林函数方法的基础上,提出了改进的经验格林函数方法,并用该方法对卢龙地震进行了模拟.模拟的结果表明:模拟的结果无论是地震动加速度时程还是反应谱与实际地震记录都符合得比以往好.说明改进的格林函数方法是模拟地震动的有效方法,可以在工程实践中应用推广.
Seismic fortification of buildings requires the input of ground motions, but often there is a lack of seismic records in the seismic fortification zone, which requires the simulation of ground motion.On the basis of summarizing the existing empirical Green’s function methods, an improved empirical Green’s function method is proposed, And the method is used to simulate the Lulong earthquake.The simulation results show that the simulation results are consistent with the actual seismic records both in terms of the time history of earthquake acceleration and the response spectrum, indicating that the improved Green’s function method is to simulate ground motion The effective method, can promote the application in engineering practice.
