RE: Building Separation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
What's the magical significance of 2-inches?  If it has to be 4-inches for
lateral sway, then make it 4-inches.

Otherwise, why not build them all as a unit with zero separation.  SanFran
and Japan have tons of residential "units" all built flush against each
other that perform great in EQ's.

Subject: Building Separation

I am being accused of being too conservative and I need a reality check. I
have a group of four identical row homes with a two inch separation between
them. Being identical I believe I can assume them to have identical dynamic
properties but the Delta sub MT value would seem to require a greater
separation.

My client pointed out to me that they built a similar project where the two
inch separation wasn't questioned. I note that there is an exception which
might apply here since the buildings will probably sway in phase.

My solution was to run the diaphragm through but that is impossible due to
legal requirements.

What do the list members think?

Thanks,

Mark E. Deardorff
