Analysis of the Behavior of Large-Span Structures in the Case of Ambient Vibrations Considering the Variety of Motion Possibilities
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2013, Vol 10, Issue 1
Abstract
The aim of the paper is to present the main results of the research regarding the dynamic characteristics and modal behavior of the Central ROMEXPO Pavilion at ambient vibrations, considering different variations of the possibilities of motion of the structure. The retained study models are only those parametric situations which may be considered, from the engineering point of view, with important risk in the dynamic evolution of the motion process under the action of a strong earthquake. For this purpose multichannel, simultaneous, digital recordings are performed on site and afterwards are processed using the basic records combination method. In order to validate the obtained results an ETABS structural model of the Pavilion is constructed and the signal is processed both in the computer program LabView as well as in DaisyLAB.
