摘要

The first cable-stayed pedestrian bridge using ultra-high performance concrete (UHPC) has beenrndesigned and constructed in Korea, and this bridge was equipped with TMD(Tuned mass damper)rnto reduce excessive vibration and increase serviceability. To validate the performance of the TMD, arnnumber of experimental human loading tests and corresponding numerical simulations werernperformed. Explicit dynamic code, LS-DYNA was utilized to simulate the experimental tests, usingrna wheel with 6-shoes designed to mimic a pedestrian’s walk or run. Through the experimental andrnnumerical investigation, reduction of peak acceleration and increase of damping ratio is confirmedrnas expected. In this paper, procedures and results of numerical simulation is presented andrncompared with experimental results.
