ASCE 7 wind Torsion Loads
ASCE 7 wind Torsion Loads
(OP)
Are there any examples of how to apply the torsion loads to complex floor plans of 2 and 3 story residences? Would it be acceptable to break up complex plans into rectangular diaphragms and apply the torsion load to each diaphragm separately?
Thanks
Thanks

If the plan is very complex, then you should recommend the owner pay for a wind tunnel test to be done since this is what ASCE stipulates for irregular buildings. The reality is I think that a lot of engineers doing small buildings (small construction budgets) use conservative judgment estimates on complex plans by breaking them into "regular" looking pieces and then applying the ASCE wind the best they can. This saves the owner from paying for a wind tunnel test and makes sure the project stays in their office, but is not the right thing to do according to ASCE7.
Since you are dealing with residences, I doubt a wind tunnel test is ever done since residences usually don't even have engineers on them to begin with. good luck

With ASCE 7-02 you have to look at torsional loading for buildings of all heights, ASCE 7-98 required it on building greater than 60 ft in height. At least that how I read it.
