ABSTRACT
In the process of seismic-designing a structure, connections play an important role in the structure’s resistance. Among effective practices in this regard are the construction and examination of connections in a factory.
In this paper, a finite element model for precast concrete connections is presented and verified by use of existing experimental results. To this end, connections are modelled completely using the software Abaqus, and a simplified model (including beams, columns and springs) is proposed. After the simplified model is ready, its proficiency will be evaluated. The resulting diagrams from both experimental and simulated models will be compared. Moreover, the models will be subject to cyclic loading and analyzed. Seismic behavior of precast connections is compared to that of monolithic connections and the results including hysteresis curves, and damping capacity, resistance, and stiffness of connections are analyzed.
