Dear sir, Why staad pro showing the stresses value for steel plate too low?LOad is applied at the middle of the centre of the plate.so yielding will be more at centre point.I also did not understand the stress distribution for boh plates it is not same…

Sir, the bottom chord of my trusses is failing due to compression at wind load upward alone load case 5. But i want to ignore this case which will never happen alone due to dead load of 1 kn/m2 on the roof.I want to check my steel with load combinations…

Dear all Greetings. I have model here contains of the main frame "rafter +column" (for gravity load +lateral load) + the lateral system (strut pipe +x bracing). my question is :-----design output shows the highlighted member fail due to gravity…

Dear All, Currently i'm designing a gantry crane. 1. I have assigned the loading from Crab to the gantry beam as moving load (Shows in Red color), But i have no idea how to assign the loading (Shows in Green color) when gantry crane is moving along…

Does anybody designed Gantry crane using STAAD.Pro? Can anybody explain how can i assign whole surface of the rail on the ground as fixed? do i need to divide the rail in to small parts and assigned those nodes as fixed? or do i need to design Gantry…

Hello all, I have a rather unique problem that I could not find a solution to via Bentley STAAD forums or online. I have errors in defining a multilinear spring in the global -X direction for a movable structure subject to a large asymmetrical load…

Dear sir, I want to camber a steel beam . I am putting the value 750 (length/offset =30000mm/40mm(we need to camber it 40 mm)) and respect value 1.6 but results are still same with deflection 50mm .Why deflection is not decreasing? Kindly also guide…

Dear sir, In staad pro how we can camber a beam . stad file also attached.I want to camber this beam 20mm .Is it possible in staad? 6472.Str1.std

Hello, I´m designing two small guardhouses in STAAD.Pro V8i SS5, both are RC structures with slab foundations, they are almost equal in principal geometry, loading and sections, the only thing that changes considerably from one model to the other is the…

I am trying to model a Elevated steel water tank with bracing for analysis in STAAD.Pro. While modelling the structure I've encountered a problem and would like your help. The problem is: While the beam offset works perfectly for modelling a beam…

Hello all, I have a Canopy model with cable stays modeled as solid bars. They are currently failing due to "L/R-EXCEEDS" - I believe this refers to KL/r compression analysis. I do not understand why STAAD is analyzing the rods under compression when…

Hello, I was doing an FEM modelling for steel plate analysis for some temporary works loading and I am getting an error "SProStaad MFC Application has stopped working" while doing the analysis? Can STAAD support team look into this and suggest? …

Dear sir, I want to design a composite beam in staad pro and consider the weight of concrete slab manually ? is there any option to stop the staad to consider the weight automatically as per CW and concrete slab thickness? Kindly give some suggestions…

Dear sir, In My attached fil,I am creating a deck slab to make my steel beams as a composite beams.But I notice deck slab somewhere missing the steel beams .some beams are not composite?Why it is happening?do I have to add that beams manually in stad…

Dear sir, In attached stad file. I am applying the dead load 2kn/m2 as floor load. 1.somewhere I am attaching two secondary beams with primary beams with the same node.is this load distributed all over the area same as 2kn/m2 or where I am having…

I modelled analyze and designed a project using staad pro select series 5 version and noted the required area of steel for columns but when I reanalyze the same std file in new staad pro connect edition I got different area of steel. for a particular…

Hello, Is there any way that i can perform Fatigue analysis for steel member in STAAD.Pro? Thank you in advance

Dear sir, In attached stad file .I am applying the dead load 2kn/m2 as floor load. 1.somewhere i am attaching two secondary beams with primary beams with the same node.is this load distributed all over the area same as 2kn/m2 or where i am having…

Dear sir, Kindly advise how we can attach two beams with a single beam as shown in the attached drawings section 5a in staad pro.. the primary beam size is UB1016*305 AND SECONDARY TWO BEAMS ARE UC 203*203*46KG. staad file is also attached . Kindly…

Dear sir, I am doing a design calculation for cat ladder using solid plates and round bar .But it is not giving me results with utilization ratio?how i can design it.Kindly suggest me method for these profile.stad file is attached. CAT LADDR.std

Dear sir, I designed a structure by using both method.in first method i deaigned it by composite beam method.and in second method i do it with composite deck.but by using composite beams giving lower utilization ratio than composite deck method.can…

I am analysing an RCC box girder for which some peculiar tapered sections have to be created. I created a tapered rectangular section in AutoCAD 2014. I used polyline to create the 2D and then extruded it to make it a solid 3D section. Now when I import…

Is there any option to get report for the tension & compression flange stress ratio of built-up I-section for the critical load cases.

Hello, I have a model in which there is a beam divided in 3 parts because of intermediary steel members (32, 73, 78). As this beam is only restricted laterally and not vertically I gave length (Ly) in vertical direction as combined length of the beam…
