A state-of-the-art review is presented on design and research related to progressive
collapse of steel structures under fire conditions. The influence of load ratios, strength of …

Several structural collapse incidents indicate that failure usually started from beam–column
joints when exposed to abnormal loads. If the connections are sufficiently robust and there is …

This study documents important aspects of bolt assembly performance in structural steel
connections at elevated temperatures that have not been the subject of detailed …

In this paper, experimental results of the structural fire behaviour of four large-scale steel
frame test assemblies are presented. Test assemblies were made of HSS beams and …

Major events—notably the Broadgate fire in London, New York's World Trade Center
collapse, and the Windsor Tower fire in Madrid—as well as the enlightening studies at the …

This paper presents the numerical results of 6 beam–column joint tests using six types of
connections: web cleat, fin plate, top and seat with web angles (TSWA)(8mm thick angle) …

Partially restrained connections comprise intricate systems of multiple components, each
exhibiting varying degrees of performance degradation under fire conditions. Consequently …

This paper presents experimental investigations on the collapse behavior of a full-scale 36
m× 12 m steel portal frame exposed to natural fires. Extensive thermal and structural …

The mechanical features of beam-to-column joints may highly affect the resistance of steel
structures at elevated temperature. Therefore, the behaviour of steel joints under elevated …

Flush end-plate beam-to-column joints are widely used in gravity load resisting parts of steel
frames. Although generally designed to behave as pinned connections, this type of joint is …
