Design Of Base Details For Vertical Vessels


E = joint efficiency

E[ = modulus of elasticity at design temperature, psi Ab = cross-sectional area of bolts, in.2

d = diameter of bolt circle, in. VVb = weight of vessel at base, lb WT = weight of vessel at tangent line, lb w = width of base plate, in. S — code allowable stress, tension, psi N = number of anchor bolts

= allowable bearing pressure, concrete, psi Fv = minimum specified yield stress, skirt, psi Fs = allowable stress, anchor bolts, psi fLT = axial load, tension, lb/in.-circumference fix: = axial load, compression, lb/in.-circumference Ft = allowable stress, tension, skirt, psi F,. = allowable stress, compression, skirt, psi Fb = allowable stress, bending, psi fs = tension force per bolt, lb fc = bearing pressure on foundation, psi Mb = overturning moment at base, ft-lb My = overturning moment at tangent line, ft-lb

Allowable Stresses

Ft = lesser of

Renewable Energy Eco Friendly

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
