Abstract:

Nowadays, demands in the application of fiber 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 of ribbed slab reduces the material and thus the cost but the strength of the structure also reduce due to the reducing material. This paper will focus on modelling behavior of ribbed slab reinforced with steel fibre using Lusas Modeller. The structure design is in full aspect to optimize the function of steel fibre and the slab rib capability. This research focus on modelling of multiple type of steel fibre ribbed slab consist of two ribbed slab, and also three ribbed slab in similar size of 1500mm x 1000mm x 75mm using concrete Grade 30. Load was applied until failure under three point loading system. It is importance to find the ultimate strength of the sample and the behavior of structure under vertical stress. Steel fibre is expected to reduce the issue of micro crack and enhance the performance of concrete.
