Calculation of the top of the solid material silo
Thread Content
I seek guidance from experienced experts: In NB/T 47003.2-2009, in equation (50) for the calculation of the silo roof shell, what does 1.mt1 represent – the mass per unit area of the silo roof shell? Does this unit area refer to the surface area of the conical silo roof or its vertical projection area? 2. What does the additional mass referred to by mt2 mean? What does MT3 refer to, the average load? 3. In Section 6.11.3, equation (57), what does the concentrated load Wz refer to? 4. Are the loads associated with roof maintenance, platforms, and pipelines calculated under mt2, mt3, or Wz?
Uniform loads such as snow load, whereas attached loads are eccentric or concentrated loads
In the formulas here, the uniformly distributed load is not considered as snow load.
I need an answer; the calculation examples in the standards don’t include any calculations related to pouring the liquid, only stating that verification should be carried out in accordance with relevant standards!
