FINITE ELEMENT ANALYSIS OF EXTERIOR PRECAST BEAM COLUMN CONNECTION UNDER MONOTONIC LOADING
Keywords:
Precast Concrete Beam Column, Monotonic Loading, Finite Element ModellingAbstract
Computer simulation offers the potential for improved understanding of the local and global mechanisms that determine the response of structures to severe loading. The research presented here focuses on development of a finite element model using ABAQUS software to be used in investigating the behaviour of precast concrete exterior beam-column connection and compared with conventional beam column connection. Laboratory investigation of reinforced and precast concrete beam-column connections indicates that component failure may result from inelastic material behaviour of plain concrete and reinforcing steel. Thus, model development includes investigating and characterizing the behaviours of these materials. Concrete damaged plasticity model is used to represent the response of plain concrete. Comparison of computed and observed behaviour of reinforced and precast concrete elements indicates that the model used represents the local response mechanisms that determine global behaviour correctly. The current research helps one to have an improved understanding of finite element modelling of precast reinforced concrete and conventional concrete subassemblies in ABAQUS software. Comparison of load displacement diagram of RCC and precast beam column joint subjected to monotonic loading by using ABAQUS software and nonlinear modeling of connections are represented. It is observe that the precast beam column connection is giving good load displacement behaviour than conventional connection.
