Comparison and analysis of 3D-finite-element models of steelanchor-box at the cable-girder anchorage zone for long-span cable-stayed bridge

WAN Zhen,LI Qiao,MAO Xue-ming (School of Civil Engineering,Southwest Jiaotong University,Chengdu 610031,China)  
It is quite important to choose right and rational finite-element model when doing 3-dimensional nonlinear analysis to steel-anchor-box at the cable-girder anchorage zone for long-span cable-stayed bridge.But with the limitation of practical software and hardware,only the local-zone model can be adopted to analyze.And the results of analysis are influenced evidently by the finite-element models' size and boundary condition.The more reasonable method can be gained by comparing different models,which can be used to estimate the safety of practical steel-anchor-box of cable-girder anchorage.Furthermore,this method can be applied for designing and choosing type,researching and guiding model test.
