| Summary: | Precast concrete structure is not a new system in construction industry. Despite the several of advantages offer like ease in installation process, there is still a weakness especially on the stability of the whole structure where critical area at joint and connection. This issue has been a huge barrier in construction industry and become continuous topic for researcher. The connection strength is the most important part in precast system. Due to lack of standard, there are two common approaches in identifying strength and behaviour of connection, which is through experimental work and computational modelling. In this study, corbel connection at beam-column are chosen as a model for conducting a 3-dimensional finite element analysis using ABAQUS and results were validated with theory and experiments from previous study. Results of load-displacement show that the precast corbel have bending stiffness range to 4.5 kN/mm and found with ±10% different when compare to the experiment and theory. By establish the analysis and parameters; finite element analysis is an economical way to replace with tedious laboratory testing in identifying the behaviour of other precast connection. In future, researcher may gather all precast connection data for design purpose and standard development for precast system. |
