A 3D finite element analysis was carried out to study the behavior of slab-column connections in a flat slab structure under combined gravity and cyclic lateral load. Prior to simulating the behavior of the proposed model, the slab-column connection specimen by using standard orthogonal stud rail from the previous study was modeled with the purpose of verifying the results using finite element tool. Given that numerical simulation was undertaken using ABAQUS to predict the structural behavior of the above-mentioned structure. With regard to providing an accurate result, a sensitivity analysis was performed by changing different parameters, such as dilation angle, viscosity parameter, and damage parameter-strain on both in tension and compression. After gaining the close resemblance to the previous study, the proposed models were then simulated using the similar technique. In the proposed model, drop panel element was used as a replacement of stud rail. Additionally, the engineered cementitious composite material using polyvinyl alcohol fibers (PVA-ECC) was also employed due to its strain capacity of 3-5% under tension compared to 0.01% of conventional concrete. Through this study, the results showed that the effect of utilizing the PVA-ECC material could significantly improve the specimen behavior and damage tolerance.
