Abstract
This study combined experimental research and finite element numerical simulations to investigate the ultimate bearing performance of a novel anchor-box-type cable–girder anchorage structure for large-span cable-stayed bridges. The stress distribution and deformation in the structure was assessed under varying loads, and the effects of the construction parameters on peak stress in key load-bearing welds were analyzed. The proposed design exhibits a safety margin of 3.2. The simulated and experimental stress distributions agree well with experimental data, although deformation and load-bearing capacity results are non-conservative. The maximum stress in the main load-bearing welds exhibits an exponential relationship with construction parameters.
