Dear community,

We have to perform a pushover analysis of a bridge with a simple deck.

We are modeling the columns using rectangular fiber sections, while the deck is a shell element with RCSection2D. Consider that the chosen units are N and mm. Self-weight has been added as 'eleLoad' in the columns and as a Face Force in the shell.

We have tried to run a first analysis with vertical loads, but not reaching the convergency, but we are not being able to identify the mistake. Could you please give your opinion? (file attached).

Thanks!

The RCSection2D is for beam element in 2D analysis, not for shells.
For shells you need:

• A 3D material for concrete (for example ASDConcrete3D)
• A uniaxial material for steel
• Convert the uniaxial material into shell reinforcement
• Use a layered shell section to combine the above
