Abstract: The knowledge of high temperature thermal properties is critical for evaluating the fire response of concrete structures. This paper presents the effect of temperature on the thermal properties of different types of ...

Abstract: Fire performance of steel structures is highly dependent on the effectiveness of applied fire insulation. However, insulation materials are susceptible to damage under extreme loading events. A state-of-the-art review on ...

Abstract: Computer programs were developed and used to investigate the influence of various factors on the fire resistance of steel hollow structural section columns filled with steel fiber-reinforced concrete. Results from the ...

Abstract: This article presents a numerical approach in which the implicit finite element method and fracture mechanics concepts are applied to simulate crack propagation at the interface of fire insulation and truss members in steel ...

Abstract: Fire-induced spalling is one of the concerns with the use of high-strength concrete (HSC) in structural applications. Some recent studies have recommended addition of polypropylene and/or steel fibers to overcome such ...

Abstract: A specially developed two-dimensional cohesive zone finite element (CZFE) scheme is applied to simulate the fracture and delamination phenomena that occur in spray-applied fire-resisting material (SFRM) on steel structures. ...

Abstract: Predicting the response of restrained beams under fire conditions is complex owing to the development of fire-induced forces and requires finite-element or finite-differences analysis. In this paper, a simplified approach ...

Abstract: This paper presents a numerical model for evaluating internal fracture and delamination at the interface of fire insulation and steel surface in structural members. A cohesive zone model in combination with contact condition ...

Abstract: Despite ongoing research efforts aimed at understanding the structural response of ultrahigh-performance concrete (UHPC) beams, there are very limited provisions for structural design of UHPC beams, specifically under ...
