RC beam design

Hello,

 

I've a inverted U beam that I must use in a project but I cannot find ways to define this RC section in RSA. Is it even possible?

 

Also, is it possible to design this type of RC beam using the RC design module in any way?

 

Here is a screenshot of the beam:

Hi @azad.krantz 

You may design it as a T Beam

Isn't match the shape like I needed, as you can see in the attached image, the beam is shown as a T, I want to design U-RC beam with going with 4 grade slope at the middle of the beam.

You may create it using: Tools > Section definition

How to create a slope in the upper edge and in the middle of the beam so that the lower edge is without slope?

Split your bar into several pieces with variable height.

Don't worry about the shape because what matters is the mechanical characteristics

How should I split the beam at different points to get the following shape and get the correct calculation result?

First you must create a dummy beam in your model. Select this beam and split it using:

Then apply these created section at each part in the model

With this, the shape of the beam will change completely! Also, we will not reach the goal we designed.

The height of our beam start with 400 mm and it will reach 2800 mm in the middle (The highest point) of the beam and it will return to 400 mm at the end.

(Please pay attention to the attached pictures and then answer the questions.)

If you are interested in the results and not in the shape, you have 2 solutions:

Hallo Azad,

 

See picture:

I think you should check the reinforcement manually based on the beam forces.

Hallo Dennis.

 

I want to design a beam whose lower edge is a vertex and the upper edge has a slope. This model that you suggested will have a slope at the top and bottom of beam.

As you can see in the attached image, I designed the beam using Idea Statica software.

Unfortunately, the robot software is incomplete and full of bugs....
