Midas Civil - Abutment design

Midas Civil - Abutment design

Midas Civil - Abutment design

(OP)
Hi

I'm modelling the abutments of an integrated concrete bridge in Midas Civil which are sloped at approximately 2 degrees. When I apply earth pressure behind the abutments the reference level that the user selects is assumed to be flat/horizontal. As a result if I were to choose the higher end of the abutment as my reference level then the lower end will receive additional earth pressure loads and vice versa.

Has anyone come across this issue before and found a solution?

Regards
Cian

RE: Midas Civil - Abutment design

I'm not familiar with the purpose of Midas Civil, but is it important to model the slope of the abutment? Why not just consider it level for this analysis?

I want to try and reflect the geometry of the bridge as accurately as possible at this stage. I'm trying to capture the resultant forces from the combination of the sloped abutments and deck.

Looking at it since yesterday I can take a number of reference heights and apply the loading in sections (as opposed to one overall load). This will bring it closer to the actually loading scenario.
