Various optimum loads for limit state design utilizing GIS-based information

本研究从1999年至2002年进行了三年，目的是评估最佳设计的地震地面运动和风荷载的极限状态和利用基于GIS的信息。还打算进行互联网应用的操作。在第1章中，对利用GIS的现有系统进行了回顾，特别对2001年国土交通省支援的建筑物结构评价系统（SSWEB：开发既有建筑物的标准结构性能评价（首席研究员：神田纯））进行了研究，认为SSWEB是能够载入现有结果的良好系统。第二章讨论了日本某场地土壤放大系数的估算方法和土壤参数数据库的建立。第三章和第四章对结构的风荷载进行了研究。在第三章中，对影响风振响应的一个重要因素--气动阻尼进行了风洞试验，并给出了试验结果。在第四章中，结合具体实例，介绍了一种基于GIS的地表粗糙度信息反演风廓线指数的方法。在第S章中，解释了这些结果与SSWEB之间的联系。第六章总结了本研究的结论，并指出了本研究存在的问题。

This research was conducted for three years from 1999 till 2002 for purposes of the evaluation of optimum design earthquake ground motion and wind load for limit states and the utilization of GIS-based information. Operations for internet application were also intended. In chapter 1, existing systems utilizing GIS were reviewed, and in particular a building structure evaluation system (SSWEB : Development of standard structural performance evaluation for existing buildings supported by Ministry of Land, Infrastructure and Transportation in 2001(head investigator : Jun Kanda)) was examined as SSWEB will be a good system for present results to be loaded. In chapter 2, an estimation method for soil amplification and database construction for soil parameters at a site in Japan were discussed. In chapter 3 and 4, wind loads are investigated. In chapter 3, the aerodynamic damping, which is an important factor for wind response evaluation was measured in wind tunnel experiments and the results were shown. In chapter 4, an evaluation procedure of wind profile index by utilizing GIS-based surface roughness information is demonstrated with specific examples. In chapter S, linkage between these results and SSWEB is explained. In chapter 6, conclusions were stated together with future problems found in this research.
