摘要
在地震动模型的生成中,本文首次构造了行波效应因子,并用其对单条相位信息进行繁衍,不仅解决了有条件模拟中直接获取多条空间相关性天然相位信息的困难,而且可以更好地模拟出天然地震动中存在的行波效应。由于行波效应为结构抗震性能研究的一个重要作用因素,因此,本文生成的人工地震动可以作为一种更为合理的输入模式。另外,本文将行波效应因子与频域合成法相结合,相对于传统的时域合成法而言,更具有简单、高效和快速的优点。
In this ground motion model,a traveling wave effect factor has been firstly constructed and been used to multiply a single phase information. Not only it can solve the difficulties of directly obtaining multiple spatial correlation phase information from the natural ground motions,but also it can better simulate the natural features of traveling wave effect,better which is the most important one in all the effect factors of structural anti- seismic studies.Therefore,this artificially ground motion can be used as a more reasonable input mode. In addition,the traveling wave effect factor had been combined with the frequency domain method in this paper,compared to the traditional time domain method,it possessed the great advantages of simple,efficient and rapid.
