§7.1 Scope

No standard provision checks are performed in seismic provision mode. The engineer is responsible for confirming that all the members are capable of resisting the standard provision load combinations, in standard provision mode. Only the "added provisions" are performed in this special seismic mode.

§7.2 Joint Requirements

Detailing information is only provided for fully restrained joints

Per Section 8.2 the plastic bending moment of each beam (Mp), and where appropriate the moment resulting from the panel zone shear strength (Mpz) are reported. Mpz is calculated independently for each beam as Vn (panel zone strength) x Beam Depth (distance between center of flanges). The Mpz reported is the component of the panel zone moment in the direction that the beam frames into the column flange (less than the full panel-zone moment if the beam is not parallel to the column web). If no panel zone value can be calculated or the beam frames into the column web then no value is shown for Mpz in the output.

The minimum of Mp (beam moment strength) and Mpz (panel zone strength at the joint under consideration) is used to calculate the required shear strength per §8.2b (1.2D + 0.5L + 0.2S + 2M/L). Where D is the dead load, M/L is the positive live load and S is snow load if it exists. Mpz is only considered if it has a positive magnitude.
