Calibration of the Ground Motion Model Using a Simplified Stochastic Model in the Case of the Central Exhibition Pavilion ROMEXPO

Abstract:

The aim of the paper is to present the results of applying the formulae of a simplified stochastic model for the calibration of some macroscopic parameters of the ground motion, on the basis of rather rough estimates. For this purpose the basic records combinations results obtained with the aid of computer programs (DaisyLab and LABView) are used, after digital recordings on the large span and rather isolated structure of the ROMEXPO Pavilion in Bucharest were performed. A stochastic model of stationary, low intensity, ground motion (referred to in literature as microtremors or ambient vibrations) was proposed by H. Sandi (1982, 2005). This lay at the basis of the specification of input for a consistent analysis of 3D earthquake induced motion of structures, adopted in the Romanian earthquake resistant design codes.
