The cable is fixed to the lower part, its middle part is movably attached through the lower end of the steel beam bundle, the other end is movably inserted through the outer end of the steel beam and the column capital, and extended downward, and then the cable is pulled. A roof made of beams and cables that uses tension to apply compressive force and bending moment to the steel beams, causing them to curve upward, and once they reach a certain curved surface, the cables are fixed to maintain that state. In the second invention, a rearward-sloping bleacher seat is assembled, and a column having a pivoted column base is erected around the outer periphery of the bleacher seat so that its upper part is supported by the upper part of the bleacher seat. Next, a truss with the top chord as a steel beam, the bottom chord as a cable, and the web as a steel bundle is assembled on the ground and on the inclined surface of the bleachers, and one end of the steel beam of the truss is pivoted to the top of the center member. The other end of the cable is pivotally connected to the capital of the column, the inner end of the cable is fixed to the lower part of the central member, the middle part of the cable is movably attached through the lower end of the steel beam, and the other end is attached to the column of the steel beam. After movably passing through the outer end and the column head and extending it downward, tension is introduced by pulling the cable, and compressive force and bending moment are applied to the steel beam, causing it to curve upward to reach a predetermined curved surface. This method consists of constructing a roof using beams and cables, in which the cables are then fixed to maintain that state.
