Ambient Vibration Analysis of Steel Structure

Abstract

Shown the eigensensitivity-based finite element model updating and given its application to four storey space steel frame structure. The monitoring, experimental details and data-processing techniques, determination of dynamic characteristics are described. Finite element model of the structure was evaluated as a primer numerical model. The output-only modal identification results were used to update a finite element model of the building. Parameters of the starting finite element model were modified using an automated procedure to improve the correlation between measured and calculated modal parameters. Mention structure was build for the testing with aim comparing several identification techniques (including ambient vibration) and other various structural engineering research studies.
