| Summary: | Nowadays, demands in the application of fibre in concrete increase
gradually as an engineering material. Rapid cost increment of material
causes the increase in demand of new technology that provides safe,
efficient and economical design for the present and future application. The
introduction ofribbed slab reduces concrete materials and thusthe cost, but
the strength of the structure also reduces due to the reducing of material.
Steel fibre reinforced concrete (SFRC) has the ability to maintain a part of
its tensile strength prior to crack in order to resist more loading compared
to conventional concrete. Meanwhile, the ribbed slab can help in material
reduction. This research investigated on the bending strength of 2-ribbed
and 3-ribbed concrete slab with steel fibre reinforcement under static
loading with a span of 1500 mm and 1000 mm x 75 mm in cross section.
An amount of 40 kg/m steel fibre of all total concrete volume was used as
reinforcement instead of conventional bars with concrete grade 30 N/mm2
.
The slab wastested underthree-point bending. Load versus deflection curve
was plotted to illustrate the result and to compare the deflection between
control and ribbed slab. Thisresearch showsthat SFRCRibbed Slab capable
to withstand the same amount of load as normal slab structure, although
the concrete volume reduces up to 20%. |
