Structural Performance of Steel Fibre Reinforced Concrete Three-Ribbed Wall Panel on Compression

Precast reinforced concrete wall offer many advantages during construction stage. One of the advantages is fast and economical. Despite that, the structure strength is carefully design in order to provide strong and reliable elements that made up the whole building. This research focus on the structural performance of three-ribbed wall reinforced with steel fibre and apart from steel fabric as the main reinforcement (WSF). In contrast, another typical wall was constructed without using steel fabric (WOSF). The wall dimensions were 1,600 mm × 1,000 mm × 100 mm (height × length × width) reinforced with B7 of steel fabric size as well as steel fibre HE 0.75/60 using concrete grade 30. Both walls were set up as pinned-fixed at the top and bottom end. The loading consist of uniformly distributed axial load connected to hydraulic jack and has 2,000 kN capacity limit. Analysis of results was done based on the ultimate load carrying capacity, wall displacement, mode of failure and cracking pattern. The location of the maximum displacement was located at 1,450 mm from the bottom while wall WOSF occurs approximately at 1,150 mm (about 0.7 H of the wall height). Wall WSF fails by crushing as indicates due to slenderness ratio 16 less than 20 and it experienced crushing at the top end along load distribution area. Load appliance to the WOSF wall was stopped as no sign of failure can be identified as the machine already reached its capacity.
