项目摘要

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.

本研究从1999年到2002年进行了为期3年的研究，目的是对极限状态下的最佳设计地震地震动和风荷载进行评价，并利用基于gis的信息。互联网应用程序的操作也打算。在第一章中，对利用GIS的现有系统进行了回顾，特别是对建筑结构评估系统（SSWEB: 2001年国土交通部支持的现有建筑标准结构性能评估的开发（首席研究员：Jun Kanda））进行了审查，因为SSWEB将是一个很好的系统，可以加载当前的结果。第二章讨论了日本某地土壤放大估算方法和土壤参数数据库的建立。第三章和第四章研究了风荷载。第三章对风洞试验中风响应评价的重要因素气动阻尼进行了测量，并给出了测量结果。第四章通过具体实例，阐述了利用基于gis的地表粗糙度信息评价风廓线指数的方法。在第五章中，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，并提出了本研究可能存在的问题。
