Originality/value This study provides a comprehensive evaluation of the post-fire flexural behavior of CFS beams made of MS, including the effects of both air- and water-cooling methods. Unlike...

...Mohamed Hesien; Maged A. Youssef; Salah El-Fitiany Purpose Fire safety is a pivotal requirement in building codes. Prescribed design criteria have been the norm to achieve it, which imposes limitations on engineers, including the inability to accommodate new solutions/materials. The shift towards...

...Faraz Tariq Purpose Although separate studies on the influence of corrosion and fire exposure on the constitutive relationship of concrete and steel have been done, there is still a gap in knowledge on the influence of corrosion-temperature superimposition as nonlinear phenomenon. The current...

Moreover, it extends the sensitivity analysis to a variance-based analysis to assess the effect of constitutive model type, fire model type...

...T.M. Jeyashree; P.R. Kannan Rajkumar Purpose This study focused on identifying critical factors governing the fire response of prestressed hollow-core slabs. The hollow-core slabs used as flooring units can be subjected to elevated temperatures during a fire. The fire response of prestressed...

...Maha Assad; Rami Hawileh; Ghada Karaki; Jamal Abdalla; M.Z. Naser Purpose This research paper aims to investigate reinforced concrete (RC) walls' behaviour under fire and identify the thermal and mechanical factors that affect their performance. Design/methodology/approach A three-dimensional...

...Huseyin Saglik; Airong Chen; Rujin Ma Purpose Beginners and even experienced ones have difficulties in completing the structural fire analysis due to numerical difficulties such as convergence errors and singularity and have to spend a lot of time making many repetitive changes on the model...

...Tulio Coelho; Sofia Diniz; Francisco Rodrigues; Ruben Van Coile Purpose This paper aims to investigate the state of the art for the reliability evaluation of reinforced concrete beams in a fire situation. Special emphasis is placed on addressing which parameters were considered probabilistically...

... loads such as fire. An example of a brittle failure mode of a connection is stripping the nut off the bolt shank (Shaheen et al., 2020a ; Alexander, 1977). Figure 1 compares the necking and stripping failure of bolt assemblies. Bolt stripping is essentially a shear failure and exhibits...

...Khadejah Alameen Abouleiwun; Hazem M.F. Elbakry; Muhammad Ahmed Diab; S.F. El-Fitiany Purpose In this study, the behavior of a multi-story flat plate structure during fire exposure is investigated using numerical simulations conducted with using ABAQUS software. Design/methodology/approach...

...Yu Liu; Shan-Shan Huang; Ian Burgess Purpose In order to improve the robustness of bare-steel and composite structures in fire, a novel axially and rotationally ductile connection has been proposed in this paper. Design/methodology/approach The component-based models of the bare-steel ductile...

... members are affected by torsional and flexural-torsional buckling, but the European (EN 1993-1-2) and the American (AISC 360-16) design norms do not explicitly treat these phenomena in fire situation. In this work, improved buckling curves based on the EN 1993-1-2 were extended by exploiting a previous...

...Vishal M.; Satyanarayanan K.S. Purpose This paper delineates a literature review on fire-induced progressive collapse on structures and the effect of high temperature on structures and elements. After the occurrences of fire in the World Trade Center in the USA, the researchers started...

... of the history of the material’s temperature development profile, the course and the intensity of fire exposure and how cooling conditions determines its properties. Design/methodology/approach Each specimen series was heated to the temperatures of T = 200°C, 400°C, 600°C, 700°C, 800°C and 1,000 °C...

...Muhannad R. Alasiri; Mustafa Mahamid Purpose Standard fire resistance curves such as ASTM E119 have been used for so long in structural fire practice. The issue with use of these curves that they do not represent real fire scenarios. As a result, the alternatives have been to either conduct...
