Floor load generation

ashish ashish — Thu, 15 Sep 2022 09:41:54 GMT

Kindly refer to the model attached and reference pictures.

For FLOOR LOADS created under REFERENCE LOADS I am getting "WARNING- NO MEMBERS LOADED FOR A FLOOR LOAD GENERATION."

However, in the GUI the same panel is indicated as loaded for the load I am getting the warning for. I am getting a total of 14 warnings.

I don't know where I am mistaken.communities.bentley.com/.../6011.Building-2.STD

The ALL specification while using Compression only spring spec

ashish ashish — Fri, 11 Sep 2020 07:52:55 GMT

The model is attached.

I have modelled a 2 Hinged arch. Assigned spring supports in both the radial and tangential directions and assigned them all compression only.

What I want to do, is to make the spring support in the tangential direction to be deactivated, once the spring support in the radial direction goes off. I have been using spring compression all command as described in the manual, TR.27.5 Spring Tension/Compression Specification, but, I don't know what I have been doing wrong as even though the spring support in the radial direction goes off, I am getting reactions in the tangential direction.

Kindly help.

Staad verification problem for retaining wall-Plates

ashish ashish — Mon, 30 Mar 2020 08:31:18 GMT

In verification problem for retaining wall the moment at the bottom of wall (middle portion) is given by halving the support reaction at the node. kindly explain.

Also, why the (moment/length)*length at the the concerned node doesn't equal to the support reaction moment.

Fundamental natural Period

ashish ashish — Fri, 06 May 2016 07:29:04 GMT

Hi there...

I am making a Seismic definition as per IS 1893...

I did not provide the type of structure in definition and staad calculated the value for Time period which was way too much low as per empirical relation given in IS code.. So.. how does staad calculates Fundamental natural period if the type of structure is not given...???

Thanks..

Support reaction and beam end results do not match

ashish ashish — Fri, 05 Feb 2016 05:58:05 GMT

I need held regarding the following:

Model details:

Slab (plate elements) resting on beam (member) on one long side only. Supports; fixed at both ends.

Slab size: 4m x 2m x 1m; Mesh size 0.2m x 0.2m

Beam length: 4m (split in to size of 0.2m length), Section size 200mm x 200mm

Load: Self wt of slab only

Problem:

The support reactions and the beam end forces do not match at the supported nodes.

Thanks.

Staad Pro Solid Element stress analysis

ashish ashish — Fri, 26 Jun 2015 09:30:38 GMT

What's the sign convention for the stresses in solid elements. How it is assigned as positive or negative. Is positive direction assigned to a particular stress because it acts in the corresponding Global direction(positive side). How do I make out whether it is Tensile or compressive by it's sign.

I modeled a cantilever beam using solid elements with concentrated point load at the free end, I got for Sxx, negative values at the bottom and positive at top, means that negative stress (in this case Sxx) is compressive and positive stress is tensile?
