چکیده مقاله :
This study presents a comprehensive evaluation of the performance of oversize threaded splices under cyclic loading conditions. The research includes monotonic tensile testing and cyclic loading experiments to investigate the seismic behavior of the splices. The experimental results demonstrate that the splices exhibit lower values of εu (strain at peak load) in cyclic loading compared to monotonic tensile testing. This suggests that the cyclic response can serve as a conservative lower bound for the mechanical performance of the splices. The findings highlight the importance of considering cyclic loading conditions when determining conservative lower bounds for the design and evaluation of threaded splices. Understanding the behavior and performance of threaded splices under cyclic loading is crucial for ensuring their reliable and safe operation in seismic regions.
