I did not check the existing lateral system. This does not seem feasible since the wind load would not have changed in the age of the building. The lateral load to the building was governed by the wind load not the material weight. The same wind load was in effect at the time the building was constructed as it is today therefore no changes in the lateral load to the building has taken place. Dennis Dennis, Although the lateral load may be the same, since your dead load has increased you could be overstressing (compression/buckling) the end columns in your shear walls when you combine dead load and overturning loads from wind. Obviously this will depend on your roof framing plan, shear wall openings, and the percent increase your new roof load is distributed to your boundary elements. Thomas Hunt ...
