A time domain reliability analysis procedure is proposed to estiamte risk for frame structures subjected to shore duration dynamci loading including seismic loading. The reliability of structures using the strength limit state is emphasized. The algorithm integrates the concepts of the response surface method, the finite element method, the first-order reliability method, and the iterative linear interpolation scheme. Both the material and geometric nonlinearities are incorporated i nthe deterministic finite elmeent model. Actual earthquake loading time histories can be used to excite structures, enabling a realistic representation of loading conditions. With the help of an example, it is shown that the algorithm is efficient and accurate. The algorithm is verified using the monte Carlo simulation method.
