The structures that steel reinforced concrete structures(SRC) are used in the key positions and the others are reinforced concrete structures(RC) arecalled SRC-RC composition structures. According to the results of research on SRC-RCcomposition structure by Southwest Jiaotong University ,this paper analyzes the failure patterns, deformation capacity, hysteretic behavior of SRC-RC composition structure , discusses the methods of the flexural rigidity of SRC beam and the strength of joints of SRC beam-RC column. Finally ,an engineering of SRC-RC composition structure is designed.
