RE: Town Home Lateral Loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The gaps Jeff is talking about are surely not seismic separations I assume 
he has 2" max.

So you design each unit for the full wind load, even the middle units. This 
 is why Simpson went into the Moment Frame market.

The roof sheathing is continuous and the exterior sheathing are continuous. 
 Maybe that's all I need.  But if I do tie multiple units together this 
jurisdiction will ask for calculations to show how I am transferring the 
loading to multiple units.

My question to the jurisdiction would be as Bill indicated, why are the 
floor diaphragms broken at each unit. I would consider this foolish 
decision especially since they are requiring the roof and wall diaphragms 
to be continuous.

So Jeff is this a fire issue or a extra calculation issue ?

I believe there was a mention of a gap between the units.

...and ignore deflection compatibility between the units?
