Return to main page: Cross Arm Parameters

Material

Cross arms have four material types that can be selected, wood, steel, concrete and composite. The material type will determine which strength reduction factor is applied based on how the environment are configured. For example if the cross arm is set up as wood and the environments tab has a strength reduction factor of 0.3 set up for serviceability (everyday loading) then the strength of the cross arm will be derated by multiplying the ultimate strength by 0.3.
