Abstract
An efficient stochastic finite element-based procedure is proposed for the reliability analysis of three-dimensional frames with partially restrained (PR) connections. The method is based on the Advanced First-Order Second-Moment reliability analysis procedure. The Richard model is used to describe the flexible behavior of connections. The assumed stress field approach is used in the finite element formulation to compute the nonlinear structural response and the corresponding response gradients. The material properties, geometry, connection parameters and external loads are considered to be random variables. The failure criteria of the structure are expressed in terms of the ultimate and serviceability limit state functions. The proposed method directly provides information on the structural reliability.
