Reinforced Concrete Bridge Model Urgent!!

Hello, I am looking for an answer to the question of whether a reinforced concrete bridge can be solved in İdecad. I made a model for it. I defined the retaining wall at the bridge support ends and placed the beams on the retaining walls. I have defined 1 m columns to support the beam ends (though I am not sure of the load transfer between the column and retaining wall here). I am attaching the model, I would be very happy if you examine it and share your thoughts and possibilities.
 
Hello, Retaining walls are elements independent of the structure. They do not dissolve with the structure and do not take load from the carrier elements and do not transfer loads. Good work
 
In spillway bridges, loads from the floor and beam are transferred to the retaining wall. Therefore, retaining walls become a part of the carrier system as bridge piers. Best regards.
 
Levent Bey talks about the account acceptance of the retaining wall element in ideCAD.
 
sa levent, can you examine this bridge and have a look at it. We haven't built a bridge before, but I wonder if this is the logic..
 
Hello, The project you added is a system consisting of columns and beams and panels. It would be appropriate to consult experts on the subject whether the bridge can be modeled in this way, what kind of loading and investigations will be made.
 
If you do not have support bands on the bridge, that is, if the beams are fixed in place and transmit moment, you can make a modeling like this. 1. In your project, cancel the columns and connect the beams to the curtains. 2. Add random point live loads on the slab to represent vehicle axle loads For example Q= 10t and ensure that there is a total of 16 tons of live single load per 10 m2 bridge slab. You can take the slab mobile and fixed loads of 500 kg/m2. 3. As a result of your analysis, the most unfavorable load combinations in the bridge beams and the beam in which the most reinforcement comes out, manually equalize the other beam reinforcements with the negative beam. 4. If not required, you can keep the slab thickness 20 cm to reduce weight. But of course it could be at 25. 4. Revise the reinforcements obtained as a result of the calculation so that they can be applied in practice. For example, there is 16Q14 flat reinforcement in the beams in your project. Since this will not fit in that section, decrease the number by increasing the diameter of the iron. Check this on all elements. Finally, in order to remind you, my projects of nearly 20 bridges and culverts with different spans (maximum 8 m) that I have drawn in this way have been implemented in Bolu. It has been serving for years.
 
Idestatic is a software designed for reinforced concrete buildings. Other programs of this kind cannot help you with this. It is not possible to learn these subjects from the program. Bridge is a distinctive engineering field that requires expertise. It requires special software and knowledge and experience. I would advise you not to attempt this at all without having this kind of experience.
