Issues regarding the civil foundation of the tower
Thread Content
The civil engineering department asks the tower design team to provide the minimum net weight of a device – what is the purpose of this? Other parameters such as operating weight and maximum weight, as well as the normal bending moment natural frequency period, have already been mentioned. Now we need to discuss the minimum net weight as well. The issue is that it’s not clear under what conditions this minimum net weight applies; calculating it for a mere shell structure gives the minimum value, but such a scenario hardly ever occurs in reality. This parameter determines whether to set a higher level of safety or a lower one. I would also appreciate some advice from fellow professionals in civil engineering
It is necessary to calculate the basic load variations in order to determine the stiffness of the foundation
Please explain in more detail. Is it true that the greater the load variation, the greater the stiffness of the foundation required?
The minimum net weight of the equipment is not relevant for civil engineering; the equipment team only needs to provide the diameter of the foundation bolts, as well as the maximum mass of the tower (with water inside) and the maximum bending moment at the tower’s base plate
What was mentioned earlier are exactly these points; only this one company requires a minimum net weight to be specified. Therefore, I would like to know how this aspect was considered.
You can ask him what he plans to do with this weight: lol
In the basic parameters specified by the design institute for the skirt foundation, it is necessary to enter the static mass of the tower equipment, the mass of detachable components, the maximum operating mass, and the mass of water filled in. The calculation of the skirt base of your tower also takes these operating conditions into account, and the calculation of the civil foundation does as well. For example, if your tower is heavy during hydrostatic pressure tests, then its foundation bolts may not be subjected to tensile forces under wind and seismic loads; however, in operating conditions where the load is light, these bolts are likely to experience tensile forces. It is also necessary to determine which type of condition is the most demanding.
