Very popular in Arch bridges, railway truss bridges , roof structures, sports stadiums, multi storey frame buildings with excellent seismic resistance.

Steel tubes filled with concrete behaves as a composite member. The concrete in the tube improves the stability of the thin-walled steel tube in compression and delays its local buckling while steel tube confines the inside concrete resulting triaxial compression stress state in the concrete.
