Wind loads on Row Homes
Wind loads on Row Homes
(OP)
We do analysis and design of Brownstone dwellings in NYC. Most of the time we are working with one dwelling in a row of same sized dwellings (often more than 6 units in a row). Since these units were constructed at the same time, one could consider that the wind load applied to the structure perpendicular to the party walls that separate the units is shared by ALL of the units - but there is nothing we can find in the Code (IBC/ASCE 7 or NYC 1968 Bldg Code) that addresses this.
We've approached this conservatively and have considered load sharing for a smaller number of units, as if one of the middle units were gone... (e.g. our unit is #2 of 6 in a row and #3 burns down, so #1 and #2 share the wind load taking 50% each - this also means that #4, #5, and #6 will now see 33% of the wind each)
Is this a reasonable design approach to this? Any suggestions are welcomed!

In a place like New York City a church may be sand witched by high rise buildings on three sides, yet shielding for design calculation purposes can not be made.

I would assume that any individual unit in the structure would be quickly repaired, not upping the overall force to any portion of the structure. After all, we do not assume that a portion of any one residence will become disfuncgtional due to fire or other calamity in our designs. Why would that be different here, irrespective of any code requirements?

I would model independently.
