Help: What is the difference in the forces acting on the upper and lower supports of a spherical tank?
It’s different depending on the area; the upper part is the top, and the lower part is the bottom
Due to the presence of the tie rod, the pillar is divided into upper and lower sections. The spherical tank columns are primarily subjected to an upward force on them caused by gravity. There are also horizontal forces resulting from earthquakes and wind; these horizontal forces are transmitted to the tie rods, where they turn into both horizontal forces and a bending moment. Tie rods can withstand tensile forces, and these forces are transferred to the columns, creating vertical loads. In addition to the gravitational load, the vertical load resulting from the maximum bending moment, as well as the vertical load exerted by the tie rods on the pillars, act only on the lower portion of the pillars.
Judging from the description above, it seems to be like two pillars. Are there any spherical tanks whose pillars are divided into upper and lower sections? ? ? ?
Low-temperature, large-volume spherical tanks are generally designed in segments using a pillar structure, taking into account the requirements of the structural materials used for connecting to the spherical shell.
