Abstrakt

In this paper an ambient response analysis of the Heritage Court Building structure is presented. The work is a part of a blind test organized by Professor Carlos Ventura, University of British Columbia. The response data were analyses using two different techniques: a non-parametric based on Frequency Domain Decomposition (FDD), and a parametric technique working on the raw data in time domain, a data driven Stochastic Subspace Identification (SSI) algorithm. Both techniques identified 11 modes under 10 HZ. One case of three close modes and one case of two close modes were identified. For all modes, natural frequencies identified by the two techniques shoved good agreement, mode shape estimates were nearly identical, and damping ratios reasonably close and around 1-2% in the most cases.
