E5.1 Scope
Ordinary cantilever column systems (OCCS) of structural steel shall be designed in conformance with this section.
E5.2 Basis of Design
OCCS designed in accordance with these provisions are expected to provide minimal inelastic drift capacity through flexural yielding of the columns.
E5.3 Analysis
There are no analysis requirements specific to this system.
E5.4 System Requirements
E5.4a Columns
Columns shall be designed using the load combinations including the overstrength seismic load. The required axial strength, , shall not exceed 15% of the available axial yield strength, , for these load combinations only.
E5.4b Stability Bracing of Columns
There are no additional requirements.
E5.5 Members
E5.5a Basic Requirements
There are no additional requirements.
E5.5b Column Flanges
There are no additional requirements.
E5.5c Protected Zones
There are no designated protected zones.
E5.6 Connections
No demand critical welds are required for this system.
