The equation of the structural limiting state can be expressed : z = r - s , thereinto r and s respectively are structural resistance and load response expressed with stochastic variables , we ca 結(jié)構(gòu)的極限狀態(tài)方程可以表示為: z = r ? s ,其中r和s分別為用隨機變量表示的結(jié)構(gòu)的抗力和荷載響應(yīng),通過極限狀態(tài)方程就可以得出結(jié)構(gòu)的失效概率,或者是用可靠指標(biāo)表示的結(jié)構(gòu)的可靠度。
This method first gives a clear definition of structural limiting state : if the whole structure or part of the structure exceeds a certain state , the structure will not satisfy the a certain functional requirement stated in the designs , then the state is called the limiting state 這種方法首先給結(jié)構(gòu)的極限狀態(tài)明確的定義:整個結(jié)構(gòu)或其一部分超過某一特定狀態(tài)就不能滿足設(shè)計規(guī)定的某一功能要求,這個狀態(tài)就稱為極限狀態(tài)。
