Numerical analysis of the behavior of beam-column precast connections without continuity reinforcement
Abstract In this paper, the behavior of four beam-column connections in precast structures, without continuity reinforcement, subjected to negative bending moment was analyzed through numerical simulation using the ABAQUS®, which is based on the Finite Element Method. Nonlinear analysis was perform...

| description | Abstract In this paper, the behavior of four beam-column connections in precast structures, without continuity reinforcement, subjected to negative bending moment was analyzed through numerical simulation using the ABAQUS®, which is based on the Finite Element Method. Nonlinear analysis was performed initially with calibration using an experimental model found in the literature. The analysis showed that the filling of the beam-pillar interfaces with rigid material allows for greater stiffness and bond strength, exhibiting a secant rotational flexural stiffness at the beginning of the yield of the anchor at least 5.5 times greater than in models without filling. There are benefits in considering the rotational stiffness of this type of connection in precast single-storey or small height structures in relation to their stress distribution that provide greater competitiveness to precast structures. |
