Embodiment Construction
[0029] Take a stadium project as an example to illustrate the saddle-shaped space prestressed ring beam involved in the present invention.
[0030] ①First, arrange a number of inner ring straight columns 5 and outer ring oblique columns 6 equally, high from east to west and low from north to south, such as figure 1 , figure 2 , Image 6 Shown. The maximum height of the inner ring column 5 and the outer ring column 6 is 38.5 meters, the minimum is 22.7 meters, the inner ring column 5 has a maximum height difference of 15.8 meters, and the outer ring column 6 has a maximum height difference of 15.8 meters. The spacing is 20 meters, the spacing of each outer ring diagonal column 6 is 22 meters, the minimum distance between the top of the inner ring straight column 5 and the top of the outer ring diagonal column 6 is 10 meters, the bottom of the inner ring straight column 5 and the outer ring diagonal column The minimum distance of bottom 6 is 16 meters.
[0031] ② Then set the saddl...
