How do we analyse and design shear wall in staad ce v22 and rcdc 9.0 using the IS code.The model is prepared in staad ce using the surface option and then imported into rcdc,but does not show up in rcdc as walls.Is there incompatibility.also where to design the strip footing for shear walls in rcdc or staad?

Hi, 

I want to design my Post Tension Slab in RAM Concept after do the analysis using Staad.Pro.
However, I got the warning as per image attached.

.RAM Concept Not Connected with Staad Pro.

I use the latest version for both Staad.Pro and RAM Concept

Dear Sye
 
One question please
 
If run a 3D-FE model of my lamp post, is the software capable of calculating the P-delta effect (calculate secondary gravitational moments due the deflected shape due wind)?
 
Many thanks and regards
 
Jose

Many thanks
 
When applying the pressure, I will apply it to half of the circle, then I will check the reaction value to check wind load has been added adequately.
 
Many thanks again
 
Jose.

RE: Modelling a lamp post in FE, add load on a dummy element to add loads to lamp post.

 

Density can be zero but E cannot be zero as that would lead to numerical instability. Try using E of 1/100 or at the most 1/1000 of the E used for the rest of the members.

When modeling with plates, it is better to apply the pressure load directly on the plates (1 KN/m2). You can apply the pressure along the appropriate global direction.

STAAD Foundation Advanced Pilecap with 2 piles message

Two Pile Combination cannot resist transverse moment,hence for shear,punching,BM calculations transverse moment is ignored. So for pile cap parallel to X, Mx=0,Fz=0. And for pile cap parallel to Z, Mz=0,Fx=0.

With this message can we say that the design is ok?

RAM Elements Retaining Wall Rebar

Hello,

I am designing a retaining wall using the module in RAM Elements. I've inputted the longitudinal and transverse reinforcement that I want to use for my retaining wall but am having difficultly with the report result. It tells me that there are warnings in my design and states that "Asmin>Asprov (stem)."  So, I went to the stem portion of the report to check it out (photo inserted below) and based off the table, I see that Asreq is 0.4 in^2 whilst Asprov is 0.41in^2 so there should not be a problem there. For the stem transverse reinforcement, the minimum shrinkage and temperature reinforcement is 0.36 in^2 so I don't see a problem there either. Could you please help and clarify why I'm getting this warning?

Thank you.

Wind Loads on Open Structures with Angle Sections

July 10, 2020, 5:21 pm

I'm looking for some help in understanding how STAAD's wind loads are applied to Open Structures, specifically those constructed of angle-section members.  

In this thread from several years ago, Kris Sathia stated the following:

For wind load on single angles in OPEN type of structures, the load intensity (force per unit length of the member) is calculated in the following manner.

If a beta angle is specified, the program finds the exposed width as sqrt(L*L+W*W) where L and W are the dimensions of the legs. This term multiplied by the wind pressure gives the magnitude of the distributed load on the member and is applied as a projected load acting in the direction of that global axis.

If a beta angle is not specified, the load intensity is equal to the dimension of the larger leg multiplied by the load intensity, and applied as a projected load.

This explanation is very counter-intuitive to me.  Yet I confirmed with a test model that it works as described.  

Consider, if I add an equal-leg angle member without beta angle to a model, it will typically be oriented such that it's maximum projected width is normal to one of the global wind directions.  The maximum projected width of unequal-leg angles would not be far from perpendicular as well.  Yet STAAD uses only the width of the larger leg to determine area, not the maximum width from sqrt(L*L+W*W).  

In contrast, if I add an angle with beta angle, it's likely that I'm adjusting the orientation to be "square with the world", having legs that are horizontal and vertical.  Thus, one of the angle legs (we could assume the larger of the two) is likely to be normal to an applied wind load.  However, in this case STAAD uses the maximum width from sqrt(L*L+W*W), even though one leg is likely to contribute very little area.

Is there an explanation for why this works backwards from how it seems it should be?  Am I misunderstanding something?  Thanks in advance for any advise or suggestions.

Hi, 

Following are some questions I would like to ask,

1. May I know how to determine the stresses at top and bot stress plan of every point in a span? Is there any table or command that i can see the detailed stresses because the result show the maximum value of stresses for top and bot stresses. 

2. May I know what is the yellow circle numbers mean in diagram attached below?

3. How to turn off the yellow circle number?

Thank you.

Whether it is necessary to use offset Command in beam to combine the beam properly with column ?

Whether There will be any change in deflection / Load transfer mechanism associated with offset beam and non offset beam?

What are the uses of offset Command?

Hi!

I need some advice. Strangely enough, when I run my STAAD Model on the RC Designer, I keep getting these errors on my beams:

1. Insufficient torsion reinforcement at [segment of beam]

2. Anchorage requirements not met.

Additionally, I find it really strange that the reinforcements of my beams are always at the top? No bottom bars, just top bars. Can anyone offer some help? Thanks a lot!

Generating Mesh in Plates

July 12, 2020, 10:13 am

Hi...

I am willing to know that can we generate a mesh in a Plate (a wooden platform resting on many primary and secondary steel beams)?

The attached picture is an example of my question. In drawing 1 we can see that ABCD is a square plate connected to Nodes A, B, C, and D.  - In this case, the load applied on the Plate will directly be transferred to points ABCD but that load may not be transferred to the intermediate steel beams.

In order to make the load gets a transfer to intermediate beams, can I generate a mesh in ABCD plate that splits a big plate into the smaller mesh and connects to all the intermediate / secondary beams? This will also split the beam into smaller members. Will that affect the analysis results?

Can I generate any number of smaller mesh from a plate?

Your response is highly appreciated.

Thanks
