Comparison of composite beam design codes in China and USA

In this paper,we compare composite beam design under China's Code for Design of Steel Structures (GB50017-2003) and the US Specification for the Design,Fabrication,and Erection of Steel Safety-related Structures for Nuclear Facilities (ANSI/AISC N690-1994).Differences and similarities of the two codes are pointed out.This would be useful for engineers and researchers to design or study.
