There is no element type “HAUNCH” in STAAD.Pro. A relatively simpler way would be to break the beam and the column into segments where the haunch member is connected and then assign a higher equivalent cross sectional property to those two segments. Alternately you can also model a beam member for the haunch and assign it the IPE500 cross section. Although this would not be a cut section but as far as analysis is concerned, I don't think this would be too bad.

RE: How to Refine Mesh in RAM Concept by using point support and line support?
The program will always attempt to mesh a line of nodes to a line support or a line spring similar to what it does with a wall center line. Likewise, the program will always mesh a single node or element corner to a point spring or point support similar to a column. Thus, if you place a super-soft line spring you can affect the mesh without adversely affecting the stiffness matrix. I don't see a lot of users doing this however.
Using a soft point spring at the location of a point load is one specific recommended use for this approach. For large loads, placing a column above at a point load has the added advantage that the column is always visible (on most plans), automatically influences strip generation and allows for a punching shear check.

How to Refine Mesh in RAM Concept by using point support and line support?
Hello everyone,
As explained in the manual of RAM Concept, Chapter 18 section 18.2, you can refine your mesh by using point support and line supports. This can be done after you have input your design strips. In other words, once you completed in putting your strips and meshing the slab, you can still refine it again. However, the manual does not explain very well the steps you need to do. Anyone have idea how can we refine the mesh, using point and line supports?
Thank you

RE: Brackets in Staad.Pro
One of the other programs that has an explicit tool for creating haunches is Ram Elements, though the steel design of haunched members there is limited to the BS 5950 and AS 4100 codes.
Hopefully we can get that same functionality into STAAD(X)

Brackets in Staad.Pro
I am working with some frames that I consider they need to be strengthened with some brackets in the joints of the column and the roof beams (see the attached picture). I know that it is possible in other software like ROBOT.
How can I do it?
Thanks in advance.

RE: MODELLING A SLAB DECK WITH PIER.
You had defined master slave joints between the top and bottom of the column which would make the column completely rigid which does not seem right. Moreover defining supports at slaved degree of freedoms is not allowed in analysis. So I commented out the lines
*SLAVE FX FZ MX MY MZ MASTER 13 JOINT 402
*SLAVE FX FZ MX MY MZ MASTER 389 JOINT 403
Number of nodes like 404 to 408 were not connected to the structure. These were removed.
The self weight was not applied to all members. So the following change was made
LOAD 1 LOADTYPE None TITLE DEAD LOAD
*SELFWEIGHT Y -1 LIST 385 TO 759
SELFWEIGHT Y -1.0
A modified file is attached.

MODELLING A SLAB DECK WITH PIER.
I am trying to model a slab superstructure with a pier. The maximum bending moment at support is on the beam connecting the pier and not equally distriduted. Kindly help.

[STAAD.Pro] Adding stiffener to section
How to determine stiffeners to the beam section in STAAD.Pro?
Does it support C section?
If it's neither quite explicit nor easy thing to do, any workaround would be highly appreciated.
Thanks!!!!

RE: RCC column design
Dear Sirs,
Sorry for digging up such an old topic. But I came across this thread on searching for this warning. I am confused by this response. Theoretically, I would assume that if the warning is an indicator of member having failed, the output should not include results (Steel reinforcement required). However, the output is including required reinforcement (and it is not necessarily near 4% - in some cases it is less than 3%). Please clarify.
Thanks in advance

RCC column design
Dear sir,
What does it mean when the out put of staad for column design says that " The number of iterations exceeded 500" ?

RE: Variable cross section beam in Staad.Pro
Can you include some figures to illustrate what you are asking about?

RE: Stress and Deflection check in post processing
Specify the ALLOY parameter with a value 39. See section 20A.4 of the International codes manual.
Note that this parameter is meant solely for design per the American Aluminum code in STAAD. If does not have any effect on the analysis results (member forces, joint displacements, support reactions, etc.). The alloy is used by STAAD exclusively to find the allowable stresses that will be used to check the adequacy of the member for interaction of axial and bending effects during aluminum design.
If you are interested in only the analysis, just specify the pipe diameter and wall thickness under the member property block of input. And, for material constants, specify aluminum as the material. If you are looking for a specific E which is different from the built-in value for aluminum, create a material with those values and assign it.

So your are suggesting is not recommended applying a point/line support to refine the mesh.

I am checking some steel members with the EC3. But I don't want they to be checked for buckling. How can I do it?
Thanks in advance.

RE: How to Refine Mesh in RAM Concept by using point support and line support?
I like to use a soft spring only because of visibility. A point or line support works just as well, but if you don't provide restraint for any of the degrees of freedom, those supports have no icon and are thus invisible on most plans.
