| Abstract: | The form,magnitude,multiple presence factors and dynamic load allowance of vehicular live loads are discussed,which have been selected in three general codes for design of highway bridges and culverts of different historical periods in recent years in the homeland.The responses of the selected structure which are aroused by vehicular live loads are comparatively systematically are analyzed and compared in the paper.The rationality of the up-to-date vehicular live loads and the developing trend of the codes have been discussed and suggested. |
