waytsh,You will need to look at a number of load combinations.Perhaps the most significant load will be the negative suction pressure on the roof1I don't think a promenade live load would be appropriate. Do you really think you'd get a large group of people up there at one time enjoying cock1Normally,you design for the snow load (25 PSF typically,although it can be reduced). You also design for a concentrated load- think it's 500 lbs1Thank you all for your input. I feel better about sticking with the roof snow load and leaving it at that. Motorcity and JStephen,just out of cTo calculate pressures from venting,you need some information on flow characteristics of the vent.You can treat it as a orifice and apply BernoulI would at least study the effect of an unbalanced load,whether your applicable code requires it or not. In reality,unbalanced snow loads do occThe slope on my roof is 3%. It looks to me like the only way ASCE would require unbalanced snow load for this slope would be under the category ofHere in Texas,the state currently requires a minimum 3/4/foot slope on tank roofs. Make sure you have it steep enough to meet applicable codes Good point. I could not find anything in IBC,but AWWA did mention a minimum 2% roof slope so I think I am ok.Coconino

STRUCTURE magazine Seismic Design of Nonbuilding

The impact of a sloshing wave on the tank roof or forcing the floating roof into a fixed roof is a continuing source of seismic damage to ground supported storage tanks.Occasionally,external floating roofs are forced outside of the tank shell by the sloshing wave and end up landing on the shell or having the seal catch the shell.SEISMIC DESIGN OF ELEVATED TANKSAny design of water tanks is subjected to Dead Load + Live Load and Wind Load or Earthquake load as per I S Code of Practice.Most of the times tanks are designed for Wind Load and not 8 Figure 4.2 Comparison of base shear coefficient for ground supported unanchored concrete water tank obtained from various codes.Most severe zone in each Roof load bearing capacity BUILDRoof structure and load bearing capacity.A roof is composed mainly of two parts - the cladding,or external material,and the internal support structure which holds it up.The amount of weight the internal support structure can carry without the roof collapsing can be described as its load bearing capacity.
