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…

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…

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…

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…

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 -…

Good Day, I have modeled a staircase in Staad using beam and plate elements, but I am unsure about the suitability of the model. My main issue I have relating to the model is whether or not the analysis results obtained for the columns are accurate…

Good Day, I have analyzed and designed a shear wall following the ACI code in Staad and would like to clarify some results.. The shear wall design has reported Edge reinforcement, however the length of this edge or boundary zone has not been reported…

Good Day Everyone, I wish to analyze and design an underground cistern (tank) using STAAD Pro. However, I would like some advice as it relates to the supporting conditions for the base plate. Based on my idealization I used plate meshes to form my surrounding…

Hi Everyone, Is it possible to get accurate analysis results from a model containing both reinforced concrete frames and structural steel frames. I am currently modelling a structure that has a reinforced concrete ground floor and a structural steel…

Slab Design 2 Deck Analysis 2.std Good Morning, I am designing grade beams (in the transverse direction) with a plate on top (acting as the deck). I have generated moving loads to go across the beams. When I look at the output files, the bending moments…

I am currently designing a deck slab, supported on grade beams (pile caps), on piles. I have created my beams, set the properties, and put a plate on top to act as the deck. My supports are the locations of the piles. I am having trouble obtaining the…
