| Abstract: | In the light of the revision of the design criteria and regulations about railway live loads in the Fundamental Code for the Design of Railway Bridges and Culverts,the paper raises a question whether type-83 piers can be normally used for live loads of the current P.R.C.railway standard.Taking account of the influences of the change in the related parameters of the beam caused by the increase of railway live loads,it deals with the necessity of checking all the related technical parameters to ensure safety,with practical calculation examples presented. |
