Reliability/Redundancy Factor

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The 1997 UBC Section 1630.1.1 has a "p" Reliability/redundancy Factor.
In equation (30-3) they have a "r" which for moment frames  is " shall be
taken as the maximum of the sum of the shears in any two adjacent columns
in a moment frame bay divided by the story shear."

My question is in reviewing a pre-engineered  single story building
 with equally spaced moment frames consisting of 1 bay of 2 columns frames,
is the shear per column one half of the story shear, thereby "r" is equal
to (1/2 V+1/2V)/V =1.

Any input on this subject is greatly appreciated.

Regards,

Nick.
