Static stress simulation error

Hello, I have been designing bridges and running static stress tests but this bridge simulation took about 3 hours, and it's not accurate, I think. I put the load in the middle but four edges decided to bend somehow.

No, you have applied uniform force over the whole of top surface:

You can change Direction Type to Angle to use Limit Target in order to limit the force to a circular region:

You can also achieve similar effect by applying Split Face in Design workspace.

By the way, I recommend first improving your model before heading to Simulation; use simple and fully-defined sketches, avoid sketch pattern and leave to Body or Feature pattern for the solid, resolve warnings (yellow icons in your timeline) as they appear, do not use Move.

Thank you, Hamid.sh., I have implemented the solution
