As to the use of high-strength steel in composite steel and reinforced concrete (SRC), structures, it remains to be clarified whether the ductile behavior can be ensured, especially when the high-strength steel is used in combination with normal-strength concrete. This paper describes the test results on the elasto-plastic behavior of SRC beams using high-strength steel, and discusses the maximum strength and the deformation capacity, with the investigation on the applicability of the concept of superposed strength. Test and analysis revealed that the behavior of SRC beams with high-strength steel was stable and of the ideal elastic-perfectly plastic type; the maximum strength of SRC beams was well predicted by the ultimate strength theory; the deformation capacity was sufficiently large; and the crack width under the short-term loading was within the limit.
