【Abstract】 Many problems are encountered in design and construction of concrete filled steel tube and steel-concrete composite structures. Therefore, we conducted a series of experimental research and engineering applications for the new steel-concrete composite structures. This paper summarizes the main research results of the past 8 years. Many optimization joints and design methods which have been applied in actual engineerings are put forward, including the RC looped-beam joint, enforced-steel loop joint, joint between columns filled with steel tubes and RC beams, joint between columns filled with steel reinforced concrete and RC columns, joint between column filled with steel tube and composite beam, composite beam design method, prestressed laminated open-web truss and so on. The suggestions presented this paper can supply references for engineering design.更多还原
