An Improved Response Surface Method for Reliability Analysis of Plate on Elastic Foundation

Abstract:

Using an improved response surface method analyzed the board of reliability on the elastic half space model. Considered the random of the larger variability parameters, such as foundation, board, load, the paper studied the reliability of this issue application of the response surface method of quadratic polynomials. This paper analyzed the influence of the random parameter variability on the reliability index β and failure probability. Comparison result shows that the convergence of the iteration of this paper is improved than the general response surface method , structural analysis to further reduce the number and improve the computational efficiency, obtained some useful conclusions and had some engineering referencing.
