项目摘要

Based on newly proposed earthquake observation programs, earthquake response characteristics of low and medium-rise buildings were investigated. Vibration characteristics and seismic performance of low and medium-rise buildings are influenced of the various effects such as the oil-structure interaction, effect of non-structural members, spatial vibration including torsion, structure-soil-structure interaction caused by closely built adjacent structure, and damping. To investigate experimentally such characteristics clearly and separately, the "strategic" observation includes such as : 1)various construction stage of a building, 2)buildings which have different combination of foundation and structural type, 3)a building which has constructing adjacent building, 4)buildings which have different height and structural type with almost same soil condition, and 5)buildings with the same type superstructure with various kinds of soil conditions, etc. Dense microtremor observation is also conducted. From analysis of observed data, the effect of soil-structure interaction for low and medium-rise buildings was especially discussed.New equipments for earthquake observation at construction site were developed with butteries and LAN connection for data acquisition. Web based database on observed records and specification of the buildings was developed with digital data download function. Real time online monitoring system was also developed for spatial vibration shapes and response wave data of a building, which is effective not only for use of structural engineering but also for disaster information system.

根据新提出的地震观察计划，研究了中型建筑的地震反应特征。低和中层建筑物的振动特征和地震性能受到各种影响，例如油结构相互作用，非结构构件的效果，空间振动，包括扭转，结构 - 土壤结构相互作用，由紧密建立的邻接结构引起和阻尼。为了清楚地和单独研究这些特征，“战略性”的观察包括：1）建筑物的各种建筑阶段，2）建筑物的建筑物，这些建筑物具有不同的基础和结构类型的组合，3）建筑物建造了相邻建筑物的建筑物， 4）具有不同高度和结构类型的建筑物几乎具有相同的土壤条件，而5）具有相同类型的上层建筑的建筑物具有各种土壤条件等。也进行了密集的微晶体观察。通过对观察到的数据的分析，特别讨论了土壤结构相互作用对中型建筑物的影响。通过黄油和LAN连接进行数据获取，开发了建筑工地的地震观察的新设备。基于Web的数据库在观察到的记录和建筑物的规范上是通过数字数据下载功能开发的。还开发了实时在线监视系统，用于建筑物的空间振动形状和响应波数据，这不仅用于使用结构工程，而且对于灾难信息系统也有效。
