CS 454 ALL1 Query

Question:

Hi, 

I am performing a bridge assessment to CS 454, using a grillage model. 
I want to apply 3 lanes of ALL1 loading, vehicle H. 
I have defined the Vehicle and the appropriate Traffic Line Lanes and want to combine them in the Moving Load Case interface. 
I can only successfully create the ML Case when the "Moving Load Optimisation" box is left UNTICKED. 

This being the case, I want to understand whether the Lane Factors and the Partial factor to the Vehicle Load are applied automatically, or if I need to apply them manually some other way. 

Best regards, 


Answer:

Hi,

Lane Factors are applied automatically as shown below.

Partial factor is only applied when the 'Auto Live Load Combination' option is checked on. For All Model 1, it is inactivated, so partial factor is not applied.

Hi, 

Thank you for clarifying. If I understand correctly then, I need to apply the Partial Factor within the Load Combination interface, is this right? Is there any other way? 
Many thanks for your time. 

Best regards, 



Yes. For the partial factor, load combination should be used.
