摘要：Plain lightweight wall panels with steel fibre and expanded polystyrene (EPS) beads, used aslightweight aggregate are tested to ascertain the structural behaviour mechanism at ultimate state. Wall samples of four(4) different sizes are prepared comprising two (2) samples for each size. Samples height and thickness are fixed to600mm and 40mm respectively, so that all samples would have a constant slenderness ratio (SR) of 15. The width ismade to vary as 320mm, 400mm, 560mm and 800mm, giving different aspect ratios (AR) of 1.875, 1.5, 1.07 and 0.75respectively. Steel fibre lightweight concrete has a compressive strength, fcu of 14.29N/mm2. The ultimate carryingstrength of the wall panel ranges from 100kN to 138kN and the highest strength is from the wall panel with aspect ratioof 1.5. All wall samples deformed in a single curvature profile with maximum lateral displacement of 6.92mmhappened at mid-height of the panel. Carrying capacity of wall panel is calculated to be inversely proportional to theaspect ratio.
