Fire Resistance of Encased Steel Stanchions.

Fire resistance of composite columns with embedded I-section steel — Effects of section size and load level

“…The effects of concrete cover, concrete type, load eccentricity on column fire resistance and limited heating on column residual strength were investigated. Test data show that (1) concrete cover significantly improved column fire resistance, and (2) lightweight concrete generally had higher fire resistance compared to normal weight concrete, the latter being more susceptible to spalling. Nevertheless, it is felt that the chosen range of load level 0.27 to 0.36 did not cover the higher end of practical load level (say 0.5, 0.6).…”

“…Some experimental works on the fire resistance of composite columns have been published [1][2][3][4][5][6][7][8][9][10][11][12][13]. The following is a summary.…”

“…In Europe, Malhotra and Stevens [1] reported fire resistance tests conducted on 14 embedded steel stanchions subjected to axial compression with a load level ranging from 0.27 to 0.36. The effects of concrete cover, concrete type, load eccentricity on column fire resistance and limited heating on column residual strength were investigated.…”

Axial restraint effects on the fire resistance of composite columns encasing I-section steel

“…There are some published works presenting experimental results on fire resistance of both concrete-filled steel tubes or encased I-section composite columns [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

“…In 1964, Malhotra and Stevens [1] reported fire resistance tests conducted on 14 encased steel stanchions subjected to axial load ratios ranging from 0.27 to 0.36. The effects of concrete cover, concrete type, load eccentricity on column fire resistance as well as limited heating on column residual strength were investigated.…”
