78m跨度预应力溷凝土刚架结构设计与施工(国外英文资料) Design and construction of 78m span prestressed concrete Yuxi stadium is a sports building with functions such as practice, competition, performance and gathering. The plane is octagon, the opposite is 72.6 m, the building total height 26.2 m, total building area 9100m2. The dome structure of the stadium is a large prestressed concrete frame with a span of 78m, with a roof system of eight curved steel frames. The outside of the steel frame is supported on the frame of the stand, which is suspended from the prestressed concrete. Roof covering pressure color plate. The prestressed concrete frame is divided into two pieces, which is arranged vertically along the stadium, with a distance of 8m. The two new frames are connected by a concrete beam, with skylights in between, to increase the natural lighting of the center of the pavilion. The column of the column is equal to the width of the column, which is tilted from the top of the frame, which is the elevation + 25.00 m, and is gradually separated to 12m. Figure 4-6-1, 4-6-2 is a simplified diagram of the floor plan and structure of the stadium. Chapter 1 rigid structure calculation The main roof structure of the stadium, which spans 78.392 m, is designed to withstand 8 degrees. The beam is made of a zig-zag section, and the girder is 5m, with a width of 1.2 m and 0.4 m. The column of the column is 1.2 m by 3.5 m, and the column is 1.2 m by 4.5 m. The column has been leaning outward to form a structure system. In the case of structural calculation, a comprehensive comparison of the models and the conditions of the site,Select two kinds of structure calculation model (space rigid frame structure calculation model, the structure calculating model of plane rigid frame) and 2 kinds of bearing constraint conditions (just answer and articulated) detailed calculation. In this paper, the internal force analysis is performed on the surface of the plane in the plane. The internal force analysis show
