This paper reviews the state-of-art in progressive collapse studies on framed building
structures. Such types of failure start with a local damage which extension increases, up to …

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 …

Finite Element (FE) methods have been widely adopted in structural design to analyze the
mechanical performance quantitatively, while most comprehensive FE models are …

To improve the anti-progressive collapse performance of top-seat and web-angle
connections, a novel bending T-stub connection (BTC) is proposed, and its tensile …

Observations from realistic fires have revealed that a fire tends to “travel” across the floors
rather than burning simultaneously for the duration. However, the collapse mechanism and …

This paper introduces experimental and numerical investigations on the fire-induced
collapse behavior of double-span steel portal frames. A natural fire test was conducted on a …

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 …

This paper presents experimental and numerical investigations on the collapse modes of
single span steel portal frames exposed to fire. A fire test on a scaled-down single span steel …

A finite-element modeling study on the progressive collapse of steel moment-resisting
frames under column removal scenarios is presented. Different parameters, such as location …

This paper presents three-dimensional progressive collapse analyses of composite steel
frames exposed to fire following earthquake. The scenarios of heating columns located in …
