In recent decades, the implemention of precast concrete structures has been considered to compensate the lower construction speed of concrete structures compared to steel structures. Execution of precast concrete structures at the factory. increases the speed to constructions and helps to improve its quality control. One of the challenging issues in precast concrete structures is the methodology to perform rigid connections. The main objective of this paper is to simulate a precast concrete beam to column connections with complex details in Abaqus finite element software.
Finite element method is one of the most common methods for solving engineering problems. It is distinguished from other methods by having lower costs compared to the laboratory methods, having higher analysis speed and accutacy, and the possibility of applying the boundry conditions accurately. Naturally, in addition to these advantages, there are some disadvantages such as: the mismatch between the laboratory and software conditions, the effect of the type and size of the selected elements on the accuracy of the problems, the impossibility of full defintion of the material property. The presence of different materials with different behavioral models along with each other ande the modeling of the interaction between the materials makes the complexity of the preconfigured concrete connection more complicated.The main issue in the process of selective connectivity simulation is the proper definition of the constraints in the software in order to provide the best possible laboratory conditions. In the research activity carried out to introduce a precast concrete connection, it has made a considerable amount of time and energy fot correct modeling and verification of the assured part of the laboratory samples. In this paper, writers have been trying to solve the challenges ahead of modeling and verification of a precast concrete connection for several months in order to share with enthusiasts.
