Abstract: This paper presents a “rotational spring” analogy which allows the geometric stiffness for a large class of structural problems to be formulated using common notions from linear structural analysis. The proposed analogy ...

Abstract: This paper presents an advanced elastic formulation intended for modeling imperfect beam-columns subject to thermal loading using only one element per member. The new formulation is derived in a local Eulerian (convected) ...

Abstract: This paper presents the application of an advanced modeling strategy for the nonlinear analysis of structures with unreinforced masonry (URM) components under blast loading. This approach enables the investigation of the ...

Abstract: This paper deals with the behavior of lightly reinforced concrete members under fire conditions, focusing on the failure state associated with rupture of the reinforcement. The work transpires from the need to examine the ...

Abstract: This paper deals with the large displacement behavior of floor slab systems under extreme loading conditions. The analytical model, presented in the companion paper, is verified through comparisons against existing ...

Abstract: In this paper, a new general procedure is presented for modeling the effects of large displacements on the response of space frames subjected to conservative loading. An incremental definition of rotations is adopted based ...

Abstract: This paper is concerned with the failure of lightly reinforced concrete members under fire conditions, with particular emphasis given to the catenary action arising from axial restraint at the supports and the ensuing ...

Abstract: This paper presents a new formulation for the large-displacement analysis of thin-walled frames taking into account the effects of elastoplastic material behavior. The proposed formulation is derived in an Eulerian (convected) ...

Abstract: The companion paper presents a new Eulerian formulation for the large-displacement analysis of thin-walled frames, accounting for the elastoplastic material response. This paper aims at verifying the proposed formulation ...

Abstract: This paper investigates the influence of unreinforced masonry panels on the robustness of multistory buildings under sudden column loss scenarios. A recently developed multilevel framework is employed to evaluate the ...
