Abstract: Geometric and physical nonlinearities are considered in the investigation of the post‐critical ultimate load conditions of space trusses. The inelastic behavior of struts is accounted for by tracing the complete stress‐strain ...

Abstract: The hysteretic behavior of a simply supported prismatic steel column with initial out‐of‐straightness subjected to cyclic loading is presented. The analysis is based on the plastic hinge concept, which under the assumption ...

Abstract: Stochastic finite-element analysis of shells is performed using the spectral representation method for the description of the random fields in conjunction with the local average method for the formulation of the stochastic ...

Abstract: The hysteretic behavior of a prismatic column subjected to cyclic loading is examined herein. An analytical model is described that includes two types of imperfections: (1) An initial out‐of‐straightness of the column and ...

Abstract: In this work, schemes based on limited‐memory quasi‐Newton methods are investigated, as applied to solving large systems of nonlinear equations with sparse symmetric Jacobian matrices. Problems in mechanics typically give ...
