Answer:The overall class of the section is Plastic. If you consider this section class to calculate the minor axis capacity, the capacity is more than the capacity reported in the output. In STAAD.Pro,...

Re: High-rise building analysis
The model contains 6749 nos. of beam elements, 160 nos. of surface elements. If you model a surface element, by default each edge of the surface gets subdivided into 10 parts at the time of analysis....

On a general note there are two aspects to backward compatibility : 1) Syntax changes in input: Every new version of STAAD.Pro comes with a set of new features that are described in the Software...

A STAAD.Pro user asks:"For a model I am running, I need to analyse it with compression only springs. The structure is placed on a trailer on which it has compression-only springs. Besides that, it will...
View ArticleRe: Compression Only Springs experiencing tension.
The supports are experiencing tension for the Load Combination cases.As the structure has Compression-Only spring supports, it is a non-linear case and one should use the “Repeat Load” syntax instead...

Mr. Sanju,In lieu 0f increasing the ratio to 1.33, it would be better in my view to multiply all the loads of the cmbination containing the seismic load with a factor 3/4. It may serve the purpose....

The code is suggesting to increase the allowable stresses induced for the seismic load combination by 33%. If we increase the factor of safety imposed on the load combination and use them in steel...

View ArticleRe: Can multiple RATIO commands apply to a single Code Check?
Mr. SanjuActually I have suggested to decrease the facotor of safety to 3/4 (0.75) so that one is not required to assign different ratio for different load case and that ratio of 1.0 would be valid for...

Re: Can multiple RATIO commands apply to a single Code Check?
If we are using Working Stress Method of design, we need to use a load factor of 1. The code is not allowing the designer to use factored load combination.Undser such a condition, we need to check the...

Mr. Sanju,Code is not prepared based on the options available in the software. Code is giving a guideline. It is for the designer to decide as to how he can achieve the stipulation of the code with the...

Please not the if we are using a code, we should strictly adhere to all the provisions and stipulations of the code. Just in case of WSM, we can not use any kind arbitrary load factors. We must use...
