A novel response surface method for structural reliability
Source abstract
Abstract
The response surface method is a common method to solve structural reliability problems. The core principle of this method is the approximation of the actual limit state function using the response surface function for subsequent analytical calculations. The existing response surface method for structural reliability has poor approximation ability and waste of the actual limit state function of the experimental points. These problems lead to low computational efficiency and inability to satisfy high-precision engineering requirements. This paper proposes a novel response surface method for structural reliability. The efficiency and accuracy are improved by the new experimental point selection strategy of the proposed method. This method has the following obvious advantages: the experimental point is close to the actual limit state function, the actual number of calculations is reduced, and the effect of the constructed response surface function approximation is improved. In addition, the single response surface function form is not used in the proposed method to improve the iterative efficiency. Compared with other response surface methods for structural reliability, three calculation examples prove the accuracy and efficiency of the proposed method.
