Abstract: This paper focuses on an inverse problem involving a commonly used material model in structural steel applications—the Voce-Chaboche model. In particular, the paper proposes an approach focused on obtaining a consistent ...

Abstract: This paper proposes a novel embedded column base (ECB) connection that defies the current paradigm in capacity-designed steel moment-resisting frames (MRFs) where column bases have been traditionally considered as ...

Abstract: Numerical models of structural components that deteriorate primarily due to geometric instabilities under multiaxis cyclic loading are sensitive to both the assumed geometric imperfections and the nonlinear material model ...

Abstract: A warping-inclusive kinematic coupling method to be used in finite-element analysis of members featuring wide-flange cross sections is proposed in this paper. This coupling method is used in mixed-dimension macromodels ...

Abstract: Tensile test data for structural steels are ubiquitous. However, the information monotonic loading provides with respect to the material’s characteristics is limited. Notably, features of inelastic response to cyclic ...

Abstract: This paper proposes a novel multiaxial plasticity model for 3-dimensional nonlinear static analysis of steel frame buildings with fiber-based beam-column elements. The proposed constitutive formulation is expressed within ...

Abstract: This paper proposes a new effective multiaxial plasticity model to simulate inelastic cyclic buckling in steel frame members. The proposed constitutive formulation is expressed within the framework of rate-independent metal ...
