The correctness of theory analysis is proved by the test results of 5 concrete-filled double steel tubular short column specimens subjected to axial compression load.

This paper studies the normal cross-section load-carrying capacity for the concrete-filled double steel tubular short columns subjected to axial compression load in which the inner and outer circle steel tubes are placed with the same circle center.

A 13-story staggered twin-truss structure was designed with staggered twin-trusses in the transverse direction and concrete-filled steel tubular double-limb columns around the outside.

Tests of five double high strength concrete filled steel tube(CFST) columns under constant axial compression and low-period alternating horizontal loads are carried out to study the seismic behaviors of double high strength CFST columns and usability of formulation of compression-bending capacity.
