Probability based load combination criteria for design of concrete containment structures
This report describes a research effort for the development of the probability-based load combination criteria for design of concrete containment structures. The proposed criteria are in a load and resistance factor design (LRFD) format. In order to test the performance objectives of the proposed criteria, four representative structures are selected using a Latin hypercube sampling technique. Next, the reliability analysis method developed by Brookhaven National Laboratory is employed to assess the reliability of these representative containments. Furthermore, an objective function is defined and a minimization technique is developed to find the optimum load factors. The load factors for accident pressure due to the design basis accident and safe shutdown earthquake are derived for three target limit state probabilities. Other load factors are also discussed on the basis of prior experience with probability-based design criteria for ordinary building construction. The proposed load combinations are based on the best available data to date pertaining to loads and resistances. If in the future the data base changes, the developed methodology can readily be utilized to update the load factors resulting from these changes.
