Load Modifiers

Enter load modifiers for Ductility, Redundancy, and Important on the tabs in this window. Refer to LRFD 1.3.2.1 for more information about load modifiers.

Ductility

Select whether your structure is Non-Ductile, of Conventional Design, or has Enhanced Ductility. Enter the ductility factor hD if you selected Non-Ductile or Enhanced Ductility. This value applies to the Strength Limit State only. All other limit states have hD=1.0

Redundancy

Select whether your structure is Non-Redundant, of Conventional Level of Redundancy, or has Enhanced Redundancy. Enter the factor hR if you selected Non-Redundant or Enhanced Redundancy. This value applies to the Strength Limit State only. All other limit states have hR=1.0

Importance

Select whether your structure is Important, of Typical Importance, or is Not Important (yeah right). Enter the factor hI if you selected Important or Not Important. This value applies to the Strength Limit State only. All other limit states have hI=1.0
