A review on application of composite truss bridges composed of hollow structural section members
Composite truss with hollow structural section (HSS) members is deemed as the structure applicable to large-span and heavily-loaded bridges. To promote the application of composite truss bridge with HSS members in China, this paper described its structural characteristics and technology in details....
