Modeling Temporary Traffic Barrier

What is the best way to model a temporary traffic barrier that is located at a two foot offset from the edge of the slab?

Model it as a regular traffic

Model it as a regular traffic barrier. Then in the stage where it is removed, model a user defined dead load that is equal and opposite to the dead load of the barrier.

Moving the Barrier

Is there a way I can move the barrier to a different location than the edge of the slab?

In the Traffic Barrier

In the Traffic Barrier library, where the shape of the girder is defined, you can input the coordinates such that the barrier is offset from the edge of the deck.

Note that PGSuper only models permanent traffic barriers. It doesn't know that you are modeling is a temporary barrier. The location of the barrier, and its interface with the deck, have an influence on the computation of live load distribution factors (the de parameter).

As an alternative, you can simply add a user defined dead load to represent the weight of the barrier.

I'm not exactly sure what you are trying to model, so apply these suggestions to your bridge with caution.
