Abstract: A linear programming (LP) formulation is proposed for the evaluation of the plastic limit temperature of flexibly connected steel frames exposed to fire. Within a framework of discrete models and piecewise linearized yield ...

Abstract: This paper presents the experimental work on 18 steel-plate girders loaded predominantly in shear. The test girders were grouped into five series, two of which were hot-rolled steel universal column sections, and the other ...

Abstract: An elastoplastic analysis of semirigid steel frames subjected to elevated temperature is presented. Within the discretized structural framework, an updated Lagrangian approach is used to incorporate the nonlinear geometric ...
