I am getting this warning: WARNING- Deflection check of member # 11 will not be performed as DFF value not provided. I am sharing the input command. Please provide your view. STAAD SPACE START JOB INFORMATION ENGINEER DATE 15-May-23 END JOB INFORMATION…

As noted in the subject title, I'm having issues with getting the hat channel members (purlins) to pass in my 3D model. The members pass if I do a bending check by hand using the same gravity load and section modulus shown in the model (Sy=Iy/c). As you…

Hi, I am using STAAD.Pro CONNECT Edition V22. The concrete structure was original modelled in revit 2018 and transferred to Staad through ISM. When the solver is run, I receive a error message ' ***ERROR*** WRONG STRENGTH PARAMETER PROVIDED'. Attached…

Hello, I created a model in 3D and was having no issues with it, until I "save as" ed the file to a different name. Now when I try to "design all" members the program force-closes, and when I try to design walls in the concrete module, I get an error…

In RAM Concepts I have a shear wall core and when looking at the mat forces it seems that the forces are concentrated at the ends of the wall and not distributing along the wall. This is causing my shear reinforcement to be very high. Is there a certain…

Dear Respected colleagues, as you can see from the attached images, i need help in modeling the true behavior of my pier system as shown in the 3D view. Since one pier is very stiff in transverse direction, there should be no deflection of any sorts but…

I am new to STAAD pro connect. I need some help on how to model a steel transition cap shown in the attached photo. The cap consists of two top and bottom plates separated by cylindrical section. There are 24 gussets attached to the outer perimeter of…

I am analyzing a 350ft+ multistory building which contains a square shear wall core. RAM Frame analysis is giving me excessive deflections (more than what I expect given the core dimensions w.r.t. floor dimensions). I wanted to know if RAM Frame would…

Hi Support Team, I have been modelling a large 3m deep transfer PT beam. (Screen shot below). Is there any Bentley software that would allow be analyse the 'True' bending stress as explained in section 52.4.2 of the user manual. Alternatively can you…

I am new in Staad pro so please answer this question in very easy language....! What is the use of Foundation support i staad pro.... can we use this instead of fixed support... what is logic behind that support....

I am designing a roof structure which is about to be supported by a mezzanine platform. The whole platform is supported on a anchor rod at different locations It will be like, there are anchor rods at several locations on the mezzanine beam, which is…

Good Day, I have been experiencing some difficulty as it relates to the design of some shear walls I wish to use for a staircase I am currently modelling in staad. I have attached the staircase model, in which I have utilized plates (to represent the…

Good day, I performed a concrete design in STAAD Pro using the moment magnification method, however, there seems to be an error as the Slenderness ratio (Klu/r) reported by STAAD is much smaller than expected. For example, Klu/r reported for Column…

There is an article in STRUCTURE magazine ( http://www.structuremag.org/?p=9911 ) that describes using shell elements in FEA software to analyze complex masonry shear walls. Are there any resources or examples that provide more information on how to do…

Hi colleague, I'm trying to perform a 3D analysis and design to a concrete structure, lateral resistance on shear wall, how is the best way to introduce the shear wall, as shell or as member, the big problem with the member I don't find the proper command…

Good day, I have analyzed the attached file without any errors, however, the post processing mode is no longer available. This is quite strange as I have already accessed post processing using this file and as such I am confused as to why post processing…

Good Day Everyone, I have completed a staad model of a staircase, however I have been recieving the following error from the shear wall design results "FAILED:NO REBAR IS AVAILABLE FOR VERTICAL REINFORCEMENT". Does any one know why this would occur…

Hi Everyone, How does staad treat out of plane forces in the design of shear walls? As I've never seen Staad generate an interaction diagram for the design of these members. Which design methodology does staad employ in its shear wall designs?

Hi everyone, 1.)How can I ensure that the moment results I obtain for my beams are accurate for a model which incorporates a plate element. I am currently modelling a staircase with the use of beam, plate and surface elements, however, the moments I…

Good day, How can I best model a footing that support perpendicular shear walls. In these cases the footing would intersect each other and would therefore share one common node. I have tried the GEN FIXED command with no errors but with the following…

Good day, I would like to find out how best can the supports for a shear wall be modeled. Considering the footing under a shear wall is continuous, placing fixed footing at the ends of the wall would suggest that the wall is only supported at these…

Hi, I'm studying the floor vibrations on a model that consisting of three floor A, B and C, despite floor A and C are symmetric, they show different ultimate acceleration because STAAD considers one of the girders only for calculating the results of…

I'm trying to model the attached floor system, and I need to make sure following points: 0- Can I draw the composite deck to cover all the floor area or do I have to draw it for every panel in the floor. because when I'm trying to cover the whole…

Good day, I have used Staad to model a composite slab and design the beams supporting this slab. However, upon completing the steel design in staad the design results presented are very strange. All the members passed, however the results only presented…

Good Day, I have done a seismic analysis and noticed the following note: ***NOTE: SEISMIC LOAD IS ACTING AT CENTER OF MASS FOR RIGID DIAPHRAGM. TORSION FROM STATIC ECCENTRICITY (esi) IS INCLUDED IN ANALYSIS. DYNAMIC ECCENTRICITY APPLIED = DEC -…
