| Abstract: |
| The response surface method for structural reliability analysis can be used when performance function is unknown, in which the iterative sequence response surface method of quadratic polynomial is often used. This paper introduces how to realize the programs of the response surface method of interpolation and BP artificial neural network(ANN) in Matlab. The contrast analysis is made among the three methods. The basic element of Matlab is matrix which provides many kinds of operation and calculation of matrix including some toolboxes in common use for the numerical computation of reliability. The advantages of matrix operation and various toolboxes can be fully used if the response surface function is adopted and programmed in Matlab. It is very efficient and convenient to program in Matlab for the reliability calculation. Because of the above advantages of Matlab, its extensive use in the structural reliability analysis will push forward the theory and application of structural reliability. |
