  • Precast concrete component in civil engineering have been popular nowadays, it is because the application of the component is having many advantages compare to the other kind of component. Although it has many advantages, the precast concrete need to estimate carefully due to the connection type. Hence, it is important to carry out the analytical simulation so it could prevent the failure on beam-column connection area. In this research will perform finite element numerical model by using ABAQUS/CAE software under monotonic load and cyclic loading and compare to experiment results. The objective of the research is to see the behavior of both of structure due to the different loading mechanism. In this study will be used 2 types of numerical model which is composite reinforced model with composite column-beam connection and pure reinforced model as normal beam-column connection. The study research revealed the behavior of reinforced concrete structure, the plastic behavior of the structure where be analysed further. It found out that the composite reinforced model could prevent the failure in connection area also increased the maximum loading force of structure. By this study, forecasted behavior of preliminary structure design can be determine and it can be a reference to prevent the failure on the future experiments.
