Hi all, I tried using Staad Pro to design the tapered section according to Eurocode and read this topic: Tapered  Section Design to Eurocode 3 EN 1993-1-1 2005 But when I design steel members with Tapered I section through defined properties, It seems…

Hi guys I'm not sure why but I cant get my utilization ratio, it shows as design property as NA

Hi, I am trying to investigate if this it is possible and relatively straight forward to important a steel frame model from AUTODESK Inventor 2023 into STAAD.Pro, without the use of Revit. Due to my current workflow process, a method which utilises…

***WARNING : MEMBER - 4 IS SLENDER AND CANNOT BE CHECKED FOR MOMENT FORCES. IF THERE IS ANY BENDING, THEN BE AWARE THAT THERE IS NO CAPACITY FOR THOSE FORCES. ONLY WIDE FLANGE SHAPES WITH SLENDER WEBS CAN BE CHECKED FOR BENDING. Why I get this warning…

We are wondering what method / programs you use to analyze and design structural supports for Cantilever Overhead Sign Structures (COSS). Do you use STAAD.Pro to generate COSS models? What engineering codes are used in your country? See videos below for…

Does anyone know how STAAD derive the following for a Class 4 section? - Minor axis bending moment capacity: if by multiplying elastic modulus with design strength, the moment capacity would be much higher than the computed values shown in STAAD output…

Hi, I have created a simply supported steel beam in the Physical Modeller (Connect Edition 22.11.00.156). I am designing the beam to the UK National Annex of Eurocode 3. I have attached 2 different models, the first is a simply supported steel beam…

4034.With Temperature_Rack.std.txt When I have applied temperature load and run the staad file it showed an abnormal unity ratio. Can you please check and suggest what is the issue? also check our applied temperature load calculation? For design,…

PDF Hello, I'm analyzing a dunnage platform under new loads imposed by eccentric pipe supports, and am attempting to do so within a RAM elements model that I inherited. As I've read about on other forums, I see that there's an option within the…

In Staad.Pro Connect Edition 22.12.00.142, whenever I design a steel beam using AISC-360 code, if I select a designed beam and go to Properties, and then Steel Design tab, I get the following screen: but, if I try to print this to PDF or to a physical…

I modeled and analyzed a Tube membered structure as per IS:800-2007 LSD in STAAD.Pro Advanced CE - V 22.12.00.142 , and tried connection design using integrated Ram Connection as Per American Code. I am encountering an error that connections are not…

Anyone can help... My properties of WF doesnt make sense. I have a beam of 1000 mm, but the properties of WF are far below 0.0 mm like this. Maybe there is a solution to my problem?

Hi, Based on NBCC 2015 4.1.8.11 4) single storey buildings with steel or wood deck as diaphragms can have a higher fundamental period compared to 4.1.8.11 3) as seen in the snap below. However, in the current RAM frame the Ta is only based on clause…

Hello. Please go through attached PowerPoint and then the below discussion will make more sense. I am using STAAD version 20.07.11.70. The main problem is: when modelling decks or bulkheads which include offset beam elements and plates attached to…

Hi I am designing a steel grating with a chequered plate and cross members. I am trying to model it in 2 ways 1. Neglecting the effect of cross members, i am modeling a composite beam (ISMB with a top plate) for the complete span. I am using BM…

In STAAD Pro SS6 edition (Version 20.07.11.70) when a member subjected to Combined Axial force and bending, the member fails with higher ratios (i.e., 200, 216584 etc. ) according to section 9.3.1.1 as per IS 800 - 2007 (LSD). But when I calculate manually…

PR-1_24072022.STD I applied Moment along Mx direction. due to that i found rotational displacement with large amount. Also note i have specie as Truss. Attached model for reference. if any mistake by me please suggest.

Hi, I was doing a case study for the combined beam & plate effect in STAAD Pro using AISC ASD. 2 geometries were prepared; 1. A simply supported beam subjected to 1kN/m UDL 2.A simply supported beam with plate structure bottom vertically restrained…

How to give the design parameter of Lx(lateral torsional buckling) For column member. In my case, The column height is 12m, Minor axis direction tied at each 3m. But major axis direction not tied. What is the Lx parameter value?

We often need to analyze existing PEMB structures and when only existing loads are applied the structure still fails. We have used the MBMA special considerations option in our design and that does not seem to help. What are we missing? Is there another…

8037.Shelter 1.std Hi, In my model some properties Steel design output are not shown in Results. I have attached model for your reference. I'm using latest STAAD connect edition.

In a steel frame structure I am modeling, For one row of beams allowable slenderness is 400 (fx = -0.005 kN) For similar second row of beams allowable slenderness is 180 (fx = 0.005 kN) and it is failing. This minuscule compressive load is making…
