Research methods: This paper makes a cooperation on BS5400 and Chinese general code for design of highway bridges and culverts(JTG D60 2004),and gives their difference and sameness. It will enhance to understand BS5400 specification for loads and combination.
Research Conclusions: It is similar between BS5400 HA and Chinese lane loads; as well as HB and Chinese vehicle loads; BS5400 HA and HB can be combined, however, the effect of lane loading and vehicle loading can not be superposed in JTG D60 2004. On the view of the total effect of loading, it focuses on safety in BS5400 codes; while for Chinese code, more consideration is given for economical result.
