| Abstract: | A response surface method（RSM） fitting with the spline function was presented.The methods of determining experiment points and fitting the response surface function were given and an improved first order reliability method（FORM） was presented for the response surface function.The examples show that the presented RSM algorithm are simply used with high accuracy. |
