【摘要】 本文将Ｗｉｌｓｏｎ－θ法与Ｊ·Ｃ方法相结合，建立了“小震”作用下索网结构各单元承载能力可靠指标与索系正常使用可靠指标的计算方法。考虑了索网结构的几何非线性特性以及静载的影响。可求出索网结构在“小震”过程中任意时刻单元承载能力可靠指标与索系正常使用可靠指标。本文方法尚可推广用于分析“小震”作用下考虑索系材料非线性时索网结构的可靠度更多还原

【Abstract】 By combining Wilson θ method with J·C method, a new method to calculate the load bearing (apacity and serviceable reliability indexes of cable roof structures under “small earthquake” is developed in this paper. The geometry nonlinear of cable roof structures and the effects of dead load on cable roof structures is taken into consideration in this new method. By using the method, the load bearing capacity and serviceable reliability indexes of cable roof structures at any one time of “small earthquake” can be calculated. The method may be improved to analysis the elastoplatic reliability of cable roof structures.更多还原
