6、structor:Professor Men.JinjieABSTRACTReinforced concrete column and steel beam (referred to as RCS) composite frame structurescombines the respective advantages of the concrete column and the steel beam components, which can make full use of the performance of steel a
7、nd concrete materials. In order to promote the development of RCS composite structure in China, six RCS beam-column composite test specimens, which interior joint with tapered-flange-type details, were designed and fabricated in the early stage of this study. At prese
8、nt, the research on the semi-rigid joints of the jointsmainly focuses on the structure of the end plate bolt connection. The
