项目摘要
The objective of the study is to evaluate seismic response characteristics of buildings by the ambient vibration test. A portable system is developed for the ambient vibration or microtremor measurement. The hardware of the system consists of portable sensors, a small amplifier, a PC-card of A/D converter and a mobile computer. The response characteristics of the system is proportional to ground velocity in the period range of 0.05 to 1 second. A 3-channel system whose weight is only 5 kg is developed for evaluation of site characteristics. For evaluation of building vibration characteristics a 12-channel system with weight of 12 kg is developed.The software of the system consists of a) the program for monitoring and data acquisition and (b) the program for spectral analyses and display of the results. The latter is developed wit.h C++ builder to be operated under the Windows OS.The time history data is easily displayed with arbitrary scale in order to select the section suitable for the analysis. The Fourier spectra and the spectral ratio are computed and displayed with arbitrary scale to understand the results in the field measurement.Using the system, microtremors of ground are measured in Yokohama and Manila, and the ambient vibration of the building is measured in Yokohama. It is confirmed that the system makes possible the very quick and efficient measurement. For example, it takes 10 minutes for the microtremor measurement and about 2 hours for the building ambient vibration test. Using the data measured the methodology for evaluation of the site characteristics is examined.
本研究的目的是借由环境振动测试来评估建筑物的地震反应特性。研制了一种便携式环境振动或微动测量系统。系统硬件由便携式传感器、小型放大器、PC A/D转换卡和移动的计算机组成。在0.05 ~ 1 s的周期范围内,系统的响应特性与地面速度成正比。研制了一个重量仅为5 kg的三通道系统,用于场地特性评价。为了评价建筑物的振动特性,研制了一个12通道、重12 kg的系统,其软件由监测和数据采集程序和频谱分析及结果显示程序组成。后者是在Windows操作系统下用C++ builder开发的,可以方便地显示任意比例尺的时程数据,以便选择适合分析的截面。利用该系统对横滨市和马尼拉市的地面脉动和横滨市的建筑物的环境振动进行了测量。实验结果表明,该系统能够实现快速、高效的测量。例如,微振测量需要10分钟,建筑物环境振动测试需要约2小时。使用测得的数据的方法进行检查的网站特性的评价。
