| Abstract: |
Highway Bridge Design Codes and Loads from AASHTO LRFD, EUROCODE and Egyptian Codes are considered. Comparisons of action effects due to Traffic Actions (Live Loads) only, and Traffic actions combined with Permanent actions ( Dead Loads) are carried out. Load combinations at ULS & SLS are considered. It is noted that comparing Traffic actions alone, a large difference is observed between codes (about 40%). When combined with Permanent actions (assuming concrete bridges), this difference reduces considerably to about 13%. Comparison of Live Load models in the Codes is not sufficient to give a full comparison of Code requirements. Hence, a brief comparison of resistance of R.C. sections in flexure and axial forces at ULS is also presented. |
