The objective of this study was to develop a method of evaluation for seismic load to be used in dynamic design of engineering structures in such a way that rationally incorporates the concept of engineering seismic risk. The results of this study are summarized as follows.1. A method of simulating risk-consistent earthquake motions was developed. The main feature of the method is that it can determine multiple ground motion parameters simultaneously on a unified probabilistic basis. The method was then generalized by proposing the concept of "hazard-consistent- magnitude and distance" thereby extending the conventional seismic hazard analysis to a multi-variate technique.2. A comprehensive state-of-the-art was developed regarding the strong motion prediction in the fields of seismology and engineering seismology. A proper guideline for the future development was specified.3. A method was developed for separating the earthquake motion recorded on the ground surface into two time history functions, one representing the fault rupture process, and the other representing the wave transmission properties of the propagation path. The method was realized by combining the use of complex cepstrum analysis with simplification of phase unlapping and filtering.4. Inelastic behavior up to failure of reinforced concrete columns under static and dynamic loads were examined experimentally on which basis its analytical model was developed and verified.

这项研究的目的是开发一种用于在工程结构的动态设计的地震负载的评估方法，以理性地结合工程地震风险的概念。这项研究的结果总结如下1。开发了一种模拟风险一致地震运动的方法。该方法的主要特征是它可以在统一的概率基础上同时确定多个地面运动参数。然后，通过提出“危险一致性和距离”的概念，从而将该方法推广，从而将常规的地震危险分析扩展到多变量技术2。关于地震学和工程地震学领域的强烈运动预测，开发了一个全面的最先进。指定了未来发展的适当指南3。开发了一种方法，将记录在地面上的地震运动分离为两个时间历史函数，一种代表断层破裂过程，另一种代表传播路径的波传输特性。通过将复杂的Cepstrum分析的使用与简化相位的不盖和滤波相结合，可以实现该方法。4。在静态和动态载荷下钢筋混凝土柱失败的非弹性行为在实验和动态载荷下进行了研究，并在该基础上开发并验证了其分析模型。
