“…But no assumption or suggestion is given for high strength steels in any current design standard of steel structures all over the world. In current literature, the available studies on post-fire performance of building structures are very few and mainly focus on steel-concrete composite joints (Pucinotti et al, 2011), concrete-filled steel tubular columns (Tao et al, 2011;Yang et al, 2008) and mild steel frames (Della Corte et al, 2003). By now, no research report on post-fire performance of high strength steel structures is available in literature.…”

Design/methodology/approach -An experimental and numerical study on seven endplate connections after cooling down from fire temperature of 550°C has been carried out and reported herein. Moreover, the provisions of European design standard for steel structures, Eurocode 3, were validated with test results of high strength steel endplate connections.Findings -In endplate connections, a proper design using a thinner high strength steel endplate can achieve the same failure mode, similar residual load bearing capacity and comparable or even higher rotation capacity after cooling down from fire. It is found that high strength steel endplate connection can regain more than 90 per cent of its original load bearing capacity after cooling down from fire temperature of 550°C.Originality/value -The post-fire performance of high strength steel endplate connection has been reported. The accuracy of Eurocode 3 for endplate connections is validated against test results.

“…However, for moment resisting frames designed according to Eurocode 8, the plastic deformation is relatively small. In this case, the reduction of mechanical properties is negligible (Della Corte et al, 2003). Therefore, an ideal elastic-perfectly plastic structure with a non-degrading component is considered in this study.…”

Fire loading following earthquake loading is possible in any building in a seismic prone area. However, most design approaches do not consider fire following earthquake as a specific loading case. Moreover, seismic design philosophies allow a certain degree of damage in structural elements which make structures more vulnerable when subjected to post-earthquake fire. This study uses three dimensional numerical models to investigate the effect of earthquake damage on the fire resistance of composite steel-frame office buildings. Two types of earthquake damage, fire insulation delamination and residual lateral frame deformation, are investigated. It is concluded that earthquake damage can significantly reduce the fire resistance of composite buildings, with delamination of fire protection having the greatest effect. The results of this study can be used by designers to improve the post-earthquake fire resistance of composite buildings.

“…The moment-rotation behaviour, lateral load-deflection behaviour, stiffness and ductility of the columns at different axial load levels were the main parameters considered in their study. Corte et al [7][8] studied the effects of structural damage caused by earthquakes on the fire resistance of steel columns and found that the impact of structural damage on fire resistance is more significant if the design of the steel structure only considers the ultimate limit state. Mohammad Hany Yassi [9] described the impact of a post-earthquake fire on the frame structure and proposed two approaches to study the damage caused by a post-earthquake fire.…”

Fire-Resistance Study of Restrained Steel Columns With Initial Lateral Displacement

2018

This study presents an analytical formula based on differential equations of equilibrium to analyse the behaviour of steel columns with initial lateral displacements in fire. The imperfections of the initial flexure of the steel columns are considered. Yielding of the edge fibres at the middle span of a column subjected to elevated temperature is designated as the failure criterion for the fire resistance of the column. After validating the results of the formula using ANSYS, a numerical application is performed to demonstrate the effects of different parameters on the ultimate load bearing capacity. The formula is then used to predict the axial force of axially restrained steel columns based on the displacement coordination condition; then, the axial force is verified by ANSYS. The axial displacement predictions from the proposed method correspond well with those obtained through the finite element method. The critical temperature can also be predicted by calculating the load bearing capacity and axial force at a certain temperature. The results show that the increase of initial lateral displacement and temperature decreases the bearing capacity of the steel column and that the critical temperature decreases with increasing constraint stiffness.
