Research results: It is similar in concrete design strength between BS5400 and Chinese Highway Code and after being divided by 1.1, the value of reinforced characteristic strength in the Chinese Highway Code is similar to that in BS5400. In reinforced concrete design, the calculated result as BS5400 is Mu=5266 kN·m, the calculated result as Chinese Highway Code is Mu=4630 kN·m, these calculated results are the basically same. Chinese Highway Code is safer than others. On short columns design, it focuses on safety in Chinese highway codes; while for BS5400, more consideration is given for economical result. On considerations affecting design details, the mini Mum areas of reinforcement in members in Chinese Highway Code is Much less than BS5400.
