A STUDY ON THE PERFORMANCE OF HIGH RISE BUILDING USING OPTICAL FIBER SENSORS IN ORDER TO ENSURE THE QUALITY OF BUILDING FROM THE DESIGN TO POST-COMPLETION STAGE

Abstract

We have been measuring the performance of plural buildings by mounting optical fiber sensors capable of measuring static and dynamic displacement on some columns of plural buildings in the process of being constructed, in order to grasp and verify their performance from the difference between the performance of actual buildings and their design performance. We analyzed the results of the measurement and reached the conclusion that measurement using optical fiber sensors is applicable to (1) evaluations of the performance of buildings, structural systems, and construction quality based on the analysis of the difference between the performance of actual buildings and their design performance, (2) feedback to future design, and (3) the estimation of the degree of damage to buildings after a disaster. In this paper, we describe particularly dynamic measurement results of the measurement we have conducted on two skyscrapers whose elevational shape is irregular, or regular, and describe the utility of the measurement system to suggest, and show future prospects.
