Experimental and finite element analysis of hybrid fiber reinforced concrete two-way slabs at ultimate limit state

Abstract Concrete is a brittle material that weak in tension and prone to internal microcracking. With the constant demand for improvement concrete’s durability mechanical proprieties, use of fiber reinforcements has shown promising results. The findings this paper are based on test results hybrid reinforced concrete (HFRC) samples simply supported two-way slabs, produced with selected volumetric proportion steel (SF) polypropylene fibers (PPF). A total twenty-one specimens were fabricated. slab tested under flexural loading their response terms strain, deflection, first crack, ultimate failure was determined. dosage SF ranged from 0.7 1.0%, whereas 0.1–0.9% PPF used by volume concrete. It found combination 0.9% 0.1% gave favorable capacity, ductility, cracks. Finite Element Analysis (FEA) proposed HFRC slabs also performed via ABAQUS. outputs numerical modeling showed close agreement experimental Using FEA model, an extensive parametric study done examine effect various parameters including longitudinal reinforcement ratio, compressive strength concrete, cover specimens. model presented outcomes.
