STUDI NUMERIK PERKUATAN PELAT DATAR BERBUKAAN SENTRAL MENGGUNAKAN BETON SERAT SINTETIS (SNFRC)

Reinforced concrete slabs are essential elements in building floor systems, but the presence of central openings for mechanical and electrical installations can reduce structural capacity and increase stress concentrations, cracks, and deformation. This study aims to evaluate the effect of using polypropylene-based synthetic fiber concrete (SNFRC) as an alternative reinforcement material for flat slabs with openings. The method used is numerical analysis based on the finite element method with the help of ABAQUS software. Modeling is carried out by referring to the shape and material from previous studies, then the results are validated by comparing them with previous numerical and experimental data to ensure the level of model accuracy. After the model is validated, the simulation is continued by varying the composition of synthetic fibers based on material data from other studies, namely 0%, 0.75%, and 1.25%. The verification results show that the model has good accuracy with a difference of 9.1% for slabs without openings and 3.1% for slabs with openings. Further analysis shows that slabs with openings experience greater deformation than slabs without openings. The addition of polypropylene synthetic fiber increases the resistance of the structure in withstanding loads as indicated by an increase in the maximum deflection value, particularly at the 1.25% fiber variation. Furthermore, the use of fibers distributes stress more evenly, reduces damage concentration, and inhibits crack development in the slab. Thus, SNFRC has the potential to be an effective, economical, and practical reinforcement method for improving the structural performance of centrally opened reinforced concrete slabs.
