Non- Linear FE Modeling of Two-Way Reinforced Concrete Slab of NSC, HSC and LWC under Concentrated Load

This paper presents the numerical study to simulate the behavior six specimens of two-way RC slab of normal strength concrete (NSC), high strength concrete (HSC) and light weight concrete (LWC) with two steel ratio of 0.005 and 0.002 under concentrated load. The finite element (FE) model is developed and the simulation environment is conducted using the commercial finite element program, ANSYS (9). The concrete material is modeled using solid elements that account for concrete cracks and other material nonlinearities. Link elements are used to model the internal steel reinforcement. The results of FE show good agreement with the experimental results.
