To Confirm Structural Coefficient for Design of Penstocks in Hydropower Stations by Partial Factors-Based Method
Zi Hou Yuan, Sun We, Yi Chen Yuan · Applied Mechanics and Materials · 2014
When confirming the partial factors in design formulas by the probability-based limit states design method (PLSDM), the structural coefficient can determined by two methods. On one hand, the structural coefficient is determined by the engineering experience calibration method, which is calculated by decomposition of the safety coefficient in the former specifications SD144-85. On the other hand, it can be determined by the probability analysis method and optimization calculation based on the target reliability index resulted from reliability calibration analysis. The appropriate value is finally determined by synthesizing results of the two methods.
