The present situations of design and construction on concrete filled steel tubular structures in Japan are described. The outlines of research works conducted in Kyushu University, such as the elasto-plastic behaviors of frames, the ultimate strength and deformation capacity of members, the limiting values of width(diameter)-tothickness ratio of cross sections, the stability and strength of slender columns, and the behaviors of truss frames are discussed. The design strengths of columns based on several foreign design standards are compared with Japanese design strength.

In order to clarify post local buckling behavior and plastic rotation capacity of steel beam-columns, cantilever steel beam-columns of H shape cross section were tested under constant vertical load and alternating horizontal load. The test program was composed of two series; fifty nine specimens of Series I tested at large amplitude of plastic deflection, and thirty three specimens of Series II tested at small plastic amplitude. Main parameters involved in the tests were the width-to-thickness ratios of the flange b/f (2b, f : width and thickness of a flange, respetively), ones of the web D/w (D : depth of a cross section, w : thickness of a web), axial load ratios n (P/P_y, P : a constant vertical load of a specimen, P_y : axial yield load of a specimen), and material pro perties of the steel (mild steel and high strength steel). Values of the parameters b/f, D/w, n are as follows : b/f=6〜16 D/w=17〜65 n=0, 0.3, 0.6 In this paper, the test program and test results are reported. Some observation from the test results are as follows : 1) Not only width-to-thickness ratio of the flange but also one of the web and axial load ratio influence on the post local buckling behavior of the steel beam-columns. 2) Not only with axial load but also without axial load, the members subjected to alternating bending shrink due to unbalance of axial load carrying capacities of the buckled flanges.
