Abstract
In present-day experimental modal analysis, multi-point force excitation techniques, where structural vibration is considered as a multi-input/output process, are often used. This paper deals with the study of base excitation modeling by modal analysis. First, multi-point random excitation techniques and curve-fit algorithms for multi-directional base excitation data, are studied. These methods are then applied to the microtremor data of boiler plant structures in thermal power stations. The identified modal parameters are shown to be in good agreement with those of FEM. As a result of these investigations, this kind of modal analysis has proven to be an effective tool for seismic modeling of large-scale structures.
