Abstract

A reconstructor of seismic responses based on the use of a spline shape function to interpolate responses recorded in a limited number of floors of a multistory building is applied in this paper to evaluate the performance of the structure during a seismic excitation. The application of the proposed technique to calculate the response of a structure does not require a mathematical or numerical model of the building but merely the availability of responses recorded at certain locations along the height of the building. The method is not influenced by parameters uncertainties or unknown disturbances. The accuracy of reconstructed responses depends both on the number and on the location of available recording sensors that have been selected applying an optimality criterion. The method has been applied to the case of a real instrumented building and its feasibility as a tool to study the performance of the structure has been checked. Performance parameters have evaluated by means of reconstructed responses and compared with the recorded ones. The comparison has shown that the spline reconstructor allows to describe the structural performance with a very good level of accuracy suggesting its usefulness for health monitoring or vibration control problems of buildings.
