The utility model discloses a novel concrete-filled steel tube staggered truss structure which is applied to a circular building, two ends of a truss are fixedly connected to concrete-filled steel tube columns, and the truss is a concrete-filled steel tube truss. A lower chord and a middle web member of the concrete-filled steel tube truss are H-shaped steel, a square steel tube with the side length equal to the width of a flange of the H-shaped steel is adopted as an upper chord, concrete with the strength grade of C30 or above is injected into the square steel tube, and the upper chord and the lower chord of the concrete-filled steel tube truss are connected with the middle web member in a welded mode. The middle web members are composed of diagonal web members and vertical web members, and the inclination angle between the lower chord member of the concrete filled steel tube truss and the horizontal plane is 6-15 degrees. The method has the beneficial effects that a larger building space and better lateral
