Reliability analysis of shear wall structures
This report describes a method for the assessment of the reliability of low-rise shear wall structures, which are often used in nuclear power plants. The shear walls are modeled by stick models with beam elements, and are subjected to dead load, live load and earthquake during their lifetimes. The earthquake load is assumed to be a segment of a stationary Gaussian process with a zero-mean and a Kanai-Tajimi power spectral density function. The seismic hazard at a site, represented by a hazard curve, is also included in the reliability analysis. Both shear and flexure limit states are analytically defined. The flexure limit state is defined according to the ACI strength design formula, while the shear limit state is established from test data. The reliability analysis methodology is described in detail. Illustrative examples are given to demonstrate the method and the applications. This reliability analysis method can also be used to generate the fragility curve of the shear wall structure.
