Ultimate Behavior of Tie Plates at High-Speed Tension
Publication: Journal of Structural Engineering
Volume 122, Issue 4
Abstract
Tie plates are integral components of pin connectors, lifting modules, and bridge restrainers. As a bridge restrainer, they are supposed to bear the dynamic seismic loads. In a previous work (Obata et al. 1991), the writers elucidated the ultimate behaviors of tie plates under quasi-static loading by the experiments and the numerical analysis. The objective of this work is to investigate the ultimate behaviors of tie plates at high-speed tension both experimentally and numerically. The high-speed tension experiments showed that the maximum strength increases with the increase of the tensile velocity. On the other hand, the deformation at the load maximum point is relatively insensitive to the tensile velocity. Therefore, the quasi-static test results always give the conservative values for the design. The numerical analysis is based on the J2 power law strain-rate-dependent plasticity theory. Despite the simplification of the complex phenomena, the numerical results give useful insights into the experimental results and in the meantime serve as reliable tools for a rational design of these tie plates.
