repeated load

The steel in the service process is often subject to strong winds, earthquakes, etc. The role of repeated load may lead to structural members repeatedly into the plastic state, so the plastic fatigue damage or even rupture.

而钢结构在服役过程中经常会受到强风、地震等重复荷载的作用，可能会导致结构构件反复进入塑性状态，从而发生塑性疲劳破坏甚至断裂。

Then every load point's reliability indices are obtained via simple multiplication and repeated addition calculations.

然后通过简单的倍乘和叠加运算计算出各负荷点的可靠性指标.
