Compression load failure of aluminum plates due to fire

Abstract

An experimental study was performed to quantify the response and failure of 5083-H116 and 6082-T6 aluminum plates under compression load while being subjected to a constant heat flux representing a fire exposure. Using an intermediate scale loading frame with integrated heating, the study evaluated the effects of geometry, aluminum type, fire exposure, load, and fire protection. Intermediate scale aluminum panels which were more than 0.7 m high and 0.2 m wide were used to gain insights into the structural behavior of large structural sections exposed to fire. Failure temperatures were measured to range from 100-480 o C and were dependent on applied stress and aluminum type. This indicates that the use of a single temperature criterion in fire resistance without load as typically done is not sufficient for evaluating structural response during fire. An empirical failure model was developed to account for fire exposure conditions, aluminum type, and geometry.

Experimental Analysis of the Behaviour of Aluminium Alloy EN 6082AW T6 at High Temperature

“…strain and modulus of elasticity from Eurocode 9 are chosen for comparison, since it provides the most regularly-used set of temperature-dependent reduction factors for alloy 6082-T6. Test results from previous studies [9,[11][12][13][14][15]19] are also compared with the proof strength and modulus of elasticity obtained in this study. These studies relate to alloys from the 6xxx series (6060-T66, 6063-T6, and 6082-T6), which represent the closest match in terms of strength value and tempering conditions compared to the studied alloy.…”

“…Fogle et al [13] investigated the failure of 5083-H116 and 6082-T6 aluminium plates exposed to constant heat flux. The main conclusion of this study was that the use of a single temperature criterion for fire resistance, without taking account of load levels, is not sufficient for predicting the structural response during fire.…”

Reinforced hybrid wood-aluminum composites with excellent fire performance

“…Among metals, aluminum alloy gained high levels of public interest due to its excellent properties of recyclability, formability, light weight, and high strength ( Hashim et al 2005 ;Fogle et al 2012 ). The literature concerning the fire performance of wood-aluminum composites (WAC) is scare.…”

Probability analysis of the fire structural resistance of aluminium plate

“…In this paper, fire resistance is defined as the capacity of a structural material to retain its load-bearing strength in fire. A large amount of experimental information is available on the softening and failure of simple aluminium structures, such as beams [1,2,4,6,9,11], wide plates [12], and hollow columns [10], exposed to actual or simulated fire. Virtually all the experimental studies have been performed on aluminium structures supporting a static compression load [1,4,10,12] or bending force [2].…”

“…The fire resistance of aluminium materials and structures has been evaluated using analytical models [1][2][3][4][5], numerical models [6][7][8][9] and experimental tests [1,2,4,6,[9][10][11][12]. In this paper, fire resistance is defined as the capacity of a structural material to retain its load-bearing strength in fire.…”
