The objective of this research project is to present the prediction model of ground motion for reasonable seismic design of structural systems on the basis of wave propagation theory and source dynamics.This project consists of two sub-projects: (I) The study on the regional factors to specify the characteristics of ground motions which would occur in Rinku town. (II)The study on prediction model of ground motion for seismic design. Sub-project(I): It has been tried to specify the active fault areas which would be important to evaluate seismic safety of a building structure in Riku town. Those areas are determined by seismic energy quantities radiated along the many faults distributed in Kinki district. Nankai trough and Chuo Kouzousen are selected as the most seismically critical and active fault areas. The soil sediment structures in Rinku town and the geolgical structure from those fault areas to bedrock have also been investigated. Sub-project(II): It has been tried to present the prediction model of ground motion for reasonable seismic design of a building structure to be built in Riku town area. To describe the refined wave propagation path and site effect model, the soil sediment structures in Riku town area and the geological structure from fault areas to the bedrock below the ground surface have been investigated. The ground motion is theoretically modeled by the Green's function from source to site and the simple source function. The validity of the prediction model is verified through a blind prediction test for observed earthquake ground motions at Ashigra valley.

本研究计画的目的是以波传播理论与震源动力学为基础，提出结构体系合理耐震设计之地震动预测模式，包含两个子计画：（一）研究区域因素，以确定临谷镇地区之地震动特性。（二）用于抗震设计的地震动预测模型研究。子项目（一）：本文试图确定活动断层区，这对评价日库镇建筑结构的地震安全性具有重要意义。这些地区是由地震能量量辐射沿着许多断层分布在近畿地区。选择南海海槽和中央口三山为最具地震危险性和活动性的断裂带。同时，还调查了临古镇的土壤沉积结构和从这些断层区到基岩的地质结构。子项目（二）：为合理地进行建筑结构抗震设计，尝试提出了日库镇地区的地震动预测模型。为了描述精细的波传播路径和场地效应模型，研究了Riku镇地区的土壤沉积结构和从断层区到地表以下基岩的地质结构。地震动理论上由震源到场地的绿色函数和简单震源函数模拟。通过对Ashigra河谷实测地震动的盲测试验，验证了该预测模型的有效性。
