Explosive spalling of concrete elements under fire is still an important issue within the
research community. In particular the effect of structural boundary conditions on …

This paper presents experimental studies on the performance of planar moment steel frames
with one column heated. The novelty of these tests is that the influences of key stages in the …

The paper represents the outcomes of a parametric experimental investigation on the
performance of rotationally restrained steel columns in fire. This experimental programme is …

The problem of columns submitted to fire is discussed in the introduction with an emphasis
on the differences between the case of a column acting as a single element or being part of …

Current concrete design codes raise concerns about concrete spalling during fire
particularly under compressive stresses and high heating rates. High-strength concrete …

This paper outlines a research program on an experimental investigation to determine the
failure time of unprotected steel columns subjected to various axial restraint ratios. Axial …

Fire tests were performed to investigate the mechanics and capacity of steel beam–columns
that develop a thermal gradient through their depth when exposed to fire. Wide-flanged …

The filling of circular hollow sections (CHS) with concrete is a good solution for
strengthening columns since such procedure increase their load bearing capacity at room …

This paper presents a numerical study on the fire resistance of embedded I-section
composite columns designed according to EC4 Pt. 1.2. The objective is to examine the …

The behavior of steel columns subjected to fire depends on their interaction with the
surrounding building structure. To improve knowledge of the phenomenon a great many fire …
