Abstract:-
This paper investigates the seismic performance of precast beam-column connections, specifically Nib and Corbel connections, under displacement-controlled cyclic loading. Laboratory tests were conducted with horizontal displacements of up to 60mm applied to the top of the column. Crack development and damage patterns were monitored throughout the testing process, and hysteresis curves were successfully derived and analyzed. Parallel to the experimental work, finite element models of similar specimens were developed using ABAQUS software. These models accounted for proper element and material properties, beam-column interaction, boundary conditions, and loading protocols. Stress distribution and hysteresis curves were extracted from the models, and the numerical results closely aligned with experimental observations, with minor deviations in moment values for the corbel connections. The combined results from both experimental and numerical analyses are presented through a proposed moment-rotation relationship, which offers a reliable basis for modeling similar beam-column connections in actual precast structures. The correlation between observed crack patterns and stress distribution further validates the finite element approach for simulating seismic behavior of these connections.
