Hello, I am designing a reinforced concrete culvert with an interior clean opening of 2m x 2m with vehicle traffic on it. I would love if there are friends who can help me with my work. I can send my design. I'm particularly stuck with party uploads. Also, would it be useful to make such a design in Sap2000? While designing in IdeCAD, my questions are: 1) Is it sufficient to add the soil-loaded combination to the loading combinations? 2) How should I load the vehicles? (Should I solve the axle loading with maximum bending and axle loading with maximum shear separately?) 3) Should the analysis be done in unit meter or is it the distance from dilatation to dilatation? 4) How should I give earthquake loads to this underground structure?
 
Hello, You can make such a design with ideCAD by defining the curtain, floor and raft basis (semi-rigid diaphragm). Define earth load by adding earth load to load combinations. For vehicle loadings, check the AASHTO (American Association of State Highway and Transportation Officials) specification for the design and construction of American Highway bridges and engineering structures. You can get the appropriate loads from the specification according to the vehicle type. You can assign these loads to the flooring and curtains by specifying points or distances and linearly.
 
I went the way you said. But I can't get rid of negative ground tension in 0.9G'+Ey+0.3Ex-0.3Ez loading. In fact, this download has started to be a problem for me in most of my projects these days. In all of them, I neglected the small yealans.

I know that there are ready-made charts of highways, you can use them

Yes, they are. But they were built in 2005. They are not 2x2 in size among those built in 2012. I want to solve it according to TBDY-2018 anyway.
 
My search for a Turkish source describing the AASHTO (American Associatin of State Highway and Transportation Officials) standard continues. I would appreciate if you share what you have or guide me so I can find it.
