The result tables of the Seismic Requirements category are available when the Earthquake Limit State was selected as the limit state type. The tables presented depend on the types of frames (SFRS) assigned in the Seismic Configurations.
Stability Bracing by Member
The required strengths and stiffnesses of the stability bracings listed in the table (see the Result Tables "Seismic Requirements" image) can be compared to the calculated available strengths and stiffnesses when designing the bracing members which frame into the beam.
There are two different values listed for the required strengths: The first value, Pbr, is applicable to the stability bracings that are located outside the plastic hinge location. The second, higher value, Pr, is for the stability bracings at the plastic hinge location. The required bracing stiffness, βbr, shall also meet the requirements of Appendix 6 of AISC 360.
Moment Frame Connection by Member
In this table, the required flexural strengths and the required shear strengths of the beam-to-column connections are listed.
Brace Connection by Member
The table lists the required tensile and compressive strengths of the braces.
