Numerical Analysis of Precast Concrete Connection in Buildings U

-Precast concrete is widely used in modern construction due to its durability, efficiency, and cost-effectiveness.

-One of the critical aspects of precast concrete structures is the connection between beams and columns. The performance of these connections is especially crucial in regions prone to seismic activity, where the forces exerted by earthquakes can challenge the stability and resilience of the structure.

-This research analyzes typical precast concrete connections, specifically nib and corbel connections, under seismic loads. The findings aim to improve the understanding of connection behaviors under cyclic loading, ensuring safer and more resilient construction practices in seismic zones buildings.
