DESIGN AND APPLICATION OF THE LONG-SPAN STEEL-CONCRETE COMPOSITE STRUCTURE

摘要

The steel-concrete composite structure has the advantages such as high load capacity, high stiffness, good earthquake resistance and dynamic performance, small section, construction convenience and so on. The structure of a hotel is complex, with many difficulties such as structure transfer, large cantilevers and long-span floors. To solve these problems, Steel-concrete composite structure such as steel-concrete composite transfer beams, steelconcrete composite cantilevers and one-way steelconcrete composite floors are proposed. Then, for each proposal, design details and notes for construction are introduced. Since components with different materials are joined together, many complex joints appear. For each kind of joint, the details are proposed. Design results of this hotel present good references for similar projects.
