| Summary: | Steel Fibre Reinforced Concrete (SFRC) has proven to be an attractive material for many applications in the civil construction industry due to it can reduce the formation of crack inside concrete. Furthermore, the excellent performance demonstrated by this composite is essentially due to its improve mechanical properties such as tensile strength, compressive strength, flexural strength and modulus of elasticity. This study describes the experiment works and the numerical model developed using London University Stress Analysis System (LUSAS) in order to understand the behavior of SFRC Ribbed Slabs structure in term of ultimate load capacity and deflection. The profile of ribbed slab, it can minimize the usage of concrete in construction industry today. The influence of steel fibers on the behavior of ribbed slab concrete structures was analyzed by performing bending tests with different number of ribs on each slab. There are two ribbed and three ribbed slab were studied having dimension 1000 mm x 1500 mm x 75 mm where two ribs and three ribs were formed for each slabs. The Hooked-ends steel fibers were used in this study. Based on the load deflection analysis, the SFRC two ribbed slab exhibited higher in term of ultimate load capacity and but lower deflection compared to SFRC three ribbed slab in experimental result. Meanwhile, the numerical result shows the SFRC two ribbed slab exhibited higher in term of ultimate load capacity and deflection compared to SFRC three ribbed slab. The result also shows that two ribbed slab design is the most suitable replacement for normal slab. Thus, on the overall, the ribbed slab has potential to be used as substitute of normal solid slab without losing strength, with concrete volume reduction and improving aesthetical values. |
