Data from Influence of Fire on the Lateral Resistance of Cold-Formed Steel Shear Walls - Phase I

Six 2.7 m by 3.7 m shear wall specimens were fabricated consisting of 150 mm wide CFS framing sheathed on one side with sheet steel adhered to Type X gypsum board and on the opposite side with Type X gypsum board. The specimens were subjected sequentially to varied combinations of mechanical (shear) deformation and thermal (fire) loading. Specimen 1 (CFS01) was used to establish the monotonic 'pushover' load-displacement capacity of the wall system and subsequently to shake down the fire test setup. Specimen 2 (CFS02) was loaded by symmetric-amplitude reverse-cyclic shear deformation to destruction (defined here as 2.8 % drift ratio) to establish the cyclic load-displacement response. Specimen 3 and 4 (CFS03 and CFS04) were cycled to deformations just before and after the peak load was achieved, respectively, burned for 13 min and 20 s and then cycling was continued until destruction of the wall. For Specimen 5 (CFS05), an undamaged wall was exposed to fire for 13 min and 20 s and then cycled to destruction. Specimen 6 (CFS06) was tested similarly to Specimen 3, however, the burn duration was doubled.
