Experimental Investigation of Steel Beam-Columns under Fire Loading
This paper presents the experimental investigation of steel beam-columns under fire loading. Experimental tests have been planned to examine the fundamental behavior of steel beam-columns. Test specimens were sequentially subjected to: (i) constant axial loading, (ii) thermal loading on the plastic hinge region followed by ASTM E119 time-temperature (T-t) curve, and (iii) monotonically increasing flexural loading. The experimental approaches involved the use of: (a) innovative radiant heating and control equipment to apply thermal loading instead of using a conventional furnace and (b) digital image processing technique incorporated with close- range photogrammetry to measure the deformation and curvature over the heated region. The measured axial force-moment-curvature-temperature (P-M-Φ-T) responses of the steel members were compared to those obtained by 3D finite element models and analyses.
