基于结构响应测量的结构参数估计

Estimation of Structural Parameters Based on Structural Response Measured by Global Positioning System

摘要:

对由GPS(Global Positioning System)系统在线监测获取的结构响应数据，进行了分析计算，给出了结构响应的空间分布及与空间位移分布相关联的谱分布，初步分析了结构响应的空间分布及谱分布所隐含的结构性能特征及结构性能变化的可能趋势.研究表明，结构响应的统计分析及谱分析是揭示隐含的结构动力性能特征的可行方法，可以作为估计结构性能差异的指标之一.

Abstract:

The real-time data of all 12 monitoring station sites obtained by kinematic Global Positioning System (RTK GPS) were analyzed and computated,and the spatial distributions and related spectrum estimations for monitoring station sites were presented.An analysis was also made of the characteristics of structural performance and its development tendency of the spatial distribution and the spectrum distribution of structural response.The research show that statistical and spectrum analysis of response is a feasible method to reveal the characters of structural response.The statistical characters of structural response can be regarded as index for estimation of structural performance difference.
