摘　　要：基于响应面法,计算考虑初始缺陷及预应力损失随机性影响的弦支穹顶结构在稳定、挠度及杆件强度三种失效模式下的失效概率。根据计算结果,确定结构的主要失效模式及结构失效概率。最终对响应面法及蒙特卡罗法计算弦支穹顶结构失效概率进行比较。Based on the response surface method,it is calculated the failure probabilities of three failure modes of the suspend-dome which considering the construction deviation and the pre-stress relaxation random distribution.The three failure mode includes stability failure,displacement failure and intensity failure.According to the result,it is gained the primary failure mode and the failure probabilities of the suspend-dome.At last the response surface method is compared to the Monte-Carlo method on the calculating of the failure probabilities of the suspend-dome.
