Atmospheric vertical storage tank
Thread Content
When designing atmospheric vertical storage tanks for foreign projects, the TANK software is used to carry out the relevant calculations for such tanks. When the wind speed is low (5 m/s), the area is not seismic, and the design internal pressure is less than 2 kPa, the calculation results indicate that anchor bolts are necessary for the tank body; however, in this case the upward force generated by the internal pressure of the tank is less than the sum of the weight of the tank roof and the tank walls. Is it then really necessary to use anchor bolts for the tank body? According to the discriminant in Figure F-1 of Appendix F of API650-2007, it is possible to omit it; how should such a situation be handled? Please ask friends for help
To determine whether anchor bolts are needed, it is necessary to calculate not only the lifting force generated by the pressure inside the tank but also the effects of wind (when the tank is empty) and vibration (when the tank is full). Since the calculation results require anchor bolts, it indicates that they are necessary under certain circumstances. (Unless there is an issue with the input data).
It might be because the diameter-to-height ratio is too small
Perhaps you didn’t include the weight of the material in your calculations, or the material is a gas with an excessively high length-to-diameter ratio (what was said on floor 3 was incorrect).
I’m sorry; what was said on the 3rd floor matches what I said. He was talking about the pitch ratio.:handshake
