Hi everyone,

I am developing a shell element model for a concrete bridge. I am currently at a stage of assigning the traffic lane UDL. 

As you can see in Figure 1, the traffic lanes are unfortunately at a angle (not 90 degrees) with respect to the horizontal direction, in other words, are not in parallel with the bridge span direction. 

My model is shown in Figure 2. It is already been meshed.

Can someone please give me some hints on selecting the elements that are under the traffic lanes; hence I can apply required UDL on them? 

if the lanes had been perpendicular to the horizontal, I would have used NSEL,S, LOC,Z,(elevation of bridge deck) and NEL,R,LOC,Y, (coordinate of the left and right boundary of the lane), to select the elements. However, it's been difficult when the angle is not 90.

Thanks.
