Abstract

This paper presents the experimental and analytical investigations on bare and composite rectangular hollow sections (RHS) which used as members of trusses. The load resistances of the trusses consisted of RHS steel and concrete-filled RHS steel tube members are compared to indicate the beneficial effects due to the in-filled concrete. The maximum load on the trusses is predicted using the design method in Eurocode 3 and Eurocode 4, and the results showed that the use of effective length method in linear analysis and design method is inconvenient and inaccurate. Finally, the results are further predicted by the second-order analysis and design method and compared with test results. The second-order analysis and design method not only gives a more accurate prediction than the linear analysis, but it also provides an efficient design as assumption of effective length is not needed.
