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

这项研究从1999年到2002年进行了三年，目的是评估极限状态下的最优设计、地震动和风荷载以及基于地理信息系统的信息的利用。互联网应用的运营也是有意的。第一章回顾了现有的利用地理信息系统的系统，特别是建筑结构评估系统(SSWEB：2001年国土交通部支持的既有建筑标准结构性能评估的发展(首席调查者：Jun Kanda))，因为SSWEB将是一个很好的系统来加载当前的结果。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。第三章和第四章对风荷载进行了研究。第三章在风洞试验中对风洞试验中的气动阻尼进行了测量，并给出了测量结果。第四章结合具体实例，介绍了利用基于地理信息系统的地表粗糙度信息进行风廓线指数评价的方法。在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，并对研究中存在的问题进行了展望。

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.
