INVESTIGATION INTO THE EFFECT OF RANDOM LOAD ON THE VARIABILITY OF RESPONSE OF PLATE BY USING MONTE CARLO SIMULATION

Considering the effect of random loads on response of structures is very important in analysis and design structures. This study deal with the behavior of plate subjected random loads by using the isogeometric analysis (IGA) and Monter Carlo method. The governing equations are derived to use higher-order plate theory. The fluctuations in the random load is modelled as two-dimensional random field. The isogeometric analysis of plate is performed in conjunction with Monte Carlo simulation (MCS). The random process of random loading is simulated by using the spectral representation method developed by Shinozuka[1, 2]. The response variability of the displacement due to random loading is evaluated in details.
