苏联创立和颁布的工程结构极限状态计算法,是一种新的先进的方法,它比以往的容许应力计算法或破坏荷载计算法,能更正确地评定出结构的承载力和可靠程度。极限状态计算法与以往方法之间的基本区别,在于它规定了结构的极限状态,并在计算上采用了系数体系以代替概括性的安全系数。所谓极限状态,就是结构的这样一种状态:达到这个状态时,结构物就失去抵抗外界影响的能
The method of calculating the ultimate state of the structure of the structure established and promulgated by the Soviet Union is a new and advanced method that can more correctly evaluate the bearing capacity and reliability of the structure than the allowable stress calculation method or the method of calculating the failure load. The basic difference between the limit state calculation method and the previous one is that it specifies the limit state of the structure and uses the coefficient system instead of the general safety factor in calculation. The so-called limit state, is the structure of such a state: to reach this state, the structure will lose the ability to resist external influences
