I. Design Overview The plane dimensions of the banquet halls and entry hall roofs of Jinling Hotel are each 31.5×31.5 meters, and each covers an area of about 1,000 square meters. Both house roofs and adjacent structures are separated by expansion joints (Figure 1). With a roof slope of 1/100, no arching will occur during construction. The roof of the roof adopts the side beam type orthogonal beam structure and the post-tensioned prestressed construction technology of cast-in-place concrete. The total load of the banquet hall roof was 1,782 tons, which was transmitted to the 8 fulcrums of 4 rectangular corner boxes through the side beams. The height of the top of the barrel (edge beam) is +11.65 meters, and the bottom is a beamless roof. Entrance hall tailgate
