Na Near-Source Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I am designing a building in Palmdale right on the San Andreas Fault with
Na=1.5. I am using simplified design base shear; building is a simple
one-story CMU box (no irregularities) so I can use reduced Na=1.3
(1630.2.3.2). So far so good.
Now the question: Can I use Na=1.3 when designing out-of-plane CMU wall and
wall anchorage to flexible diaphragm per formula 32-2 (1632.2) or do I have
to go back to Na=1.5?
