Computational analysis of reinforced concrete structures subjected to fire using a multilayered finite element formulation
TLDR
In this article, an approach using corotational layered beam is proposed to mitigate fire risk in reinforced concrete (RC) structures and appropriate structural resistance against it has to be ensured.Abstract:
Fire is a critical risk in reinforced concrete (RC) structures and appropriate structural resistance against it has to be ensured. In this contribution, an approach using corotational layered beam ...read more

On Composite Beams
TL;DR: In this paper, numerical calculations are presented to describe the behavior of a composite beam in which the concrete slab does not predominate and the neutral axis of the transformed section is well into the steel section.

Design‐oriented nonlinear‐elastic buckling analysis of reinforced concrete wall structures using convex optimization
TL;DR: In this paper , a design-oriented numerical method for efficient instability analysis of slender reinforced concrete (RC) wall structures, also enabling the inclusion of thermal effects, is presented and validated using examples with exact solutions, and its applicability to large scale models is demonstrated through an example with a four-story stairwell modeled using more than 3200 finite elements.

Effect of fire on concrete and concrete structures
TL;DR: There are three methods of assessment of fire resistance: (a) fire testing, (b) prescriptive methods, which are rigid; and (c) performance-based methods which are flexible as discussed by the authors.
