Based on the failure response curve method, and in order to fully utilize sample pionts in the iterative process,a sample points reused failure response curve (SPRFRC) method for a sample points reused failure response curve (SPRFRC) method for structural reliability analysis was developed,which regarded structural reliability index as convergence condition,selected sample points near the failure boundary from all sample points after convergence,then constructed failure curve response function and finally calculated the structural reliability by the Monte Carlo sampling method.Some examples show that the response function avoids simulation of performance function response surface,reduces the model dimension;and with introduction of the cross-term response function with rotation functionality,the function enable to approximate the failure curve,and effectively improve the reliability calculation accuracy.
