Abstract
This paper presents the evaluation of first mode damping ratios, first mode natural frequencies and amplitude dependences for a steel building based on measuring data. The building is 50 m height, rectangular plan and it was completed in March 2004. Many data are simultaneously collected in two horizontal directions at optional points on the roof floor since April 2004. We investigate the center of rigidity on the roof floor based on microtremor measurement. It is clarified characteristics of first mode damping ratios, first mode natural frequencies, and amplitude dependences on the center of rigidity based on microtremor, man power exciting, strong wind, and earthquake measurement.
