Structures

Steel-timber hybrid structures have emerged as a low‑carbon alternative to traditional steel-concrete composite systems. However, despite increasing research at ambient conditions, their fire performance remains poorly understood due to complex thermo-mechanical interactions at the steel-timber interface. This study presents a numerical investigation of the composite behaviour of hot-rolled steel…

Fire design procedures for RC columns and shear walls assume that structures are designed according to ambient-temperature (AT) standards, whose partial safety factors can provide an intrinsic fire safety margin. However, the magnitude of this margin in fire behavior has not yet been quantified. This study quantifies the intrinsic fire safety margin by comparing the fire performance of RC columns…
