API RP 2A Earthquake requirements

[Enp12444]

I keep getting mixed up when I read section 2.3.6. Earthquake in API RP 2A... Could some one help me with the following?

Is designing the primary joints for the full brace capacity a must when the strength level earthquake is higher than 0.1 g?

What if I use the ductility level acceleration and check the joint punching against the brace actual load (Based on the ductility level)do i still have to check the joints against the braces full capacity?

Just check it.

The idea is for the joints to stay intact while the brace members absorb as much energy as they can.
