Development of seismic structural response analysis method based on the fault-structure system incorporating the inversion analysis

为了进一步提高结构地震反应估计的精度，本文提出了一种基于断层-结构系统的地震反应分析方法：断层机制、地震波在地壳中的传播、近地表放大和土-结构相互作用。为了以高分辨率和高精度分析该系统，我们开发了具有解决困难的正演工具：构建三维数值模型和求解离散控制方程的计算成本非常大。通过将其与绿色函数解进行比较，验证了该正演工具的准确性。我们证明了潜在的效用的方法，通过估计在给定的地震情况下的大型和复杂的结构的地震响应。此外，为了增加这种方法的可靠性，我们还开发了一个原型的反演分析系统，包括正演工具。

With aiming to further improve the accuracy of estimate on seismic structural response, we developed a new analysis method which is based on the fault-structure system: the fault mechanism, wave propagation through the crust, amplification near the surface, and soil-structure interaction. To analyze this system at high resolution and accuracy, we developed the forward tool with resolving difficulties: the extremely large computation cost of constructing a three-dimensional numerical model and solving the discretized governing equations. The accuracy of this forward tool is verified by comparing it to a Green's function solution. We demonstrate the potential utility of the method by estimating the seismic response of a large and complex structure in a given earthquake scenario. Further, in order to increase the reliability of this method, we also developed a prototype of the inversion analysis system incorporating the forward tool.
