Q. Vessels resting on concrete foundations?

For vessels resting on concrete foundations, the allowable concrete bearing stress shall be 750 psi (5 MPa). The design loadings for anchor bolts embedded in concrete, may be determined by either the simplified method (neutral axis of bolt pattern at centerline of vessel) or the shifted neutral axis method. However, the use of the latter method is recommended for large vertical vessels because of the economic benefit. It should be noted that the neutral axis shift method does not apply for vessels supported by steel structures.
