Loading tests were conducted to evaluate the structural behavior of connection panel and subassemblage frame, which consist of high-strength concrete-filled square tubular steel (CFT) column and steel beam. The connection panel is reinforced with external vertical stiffeners which are installed between beam flanges to avoid interference with finishing material and reinforcement in floor slab. As a result of the tests, deformation capacity of the connection panel is not affected by aspect ratio of connection panels or strength of materials. Furthermore, a new analytical method which can reasonably reproduce the behavior of the connection was proposed. This analysis can calculate the load-deflection relation of the connection panel by assuming tri-linear models for steel tube and concrete respectively. Finally, the subassemblage frame behavior is represented by superimposing multi-linear models for beam to column connection, CFT column and steel beams.
