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…

Good day! I am designing exterior louvers for a certain project. They are designed to carry the code-based wind load. The thing is, it is not of a general section. The section looks like an A-shaped single skin louver with steel angle bars working as…

Dear Colleagues, current version : STAAD.Pro CONNECT Edition - Version 22.12.00.142 there was a situation where we had to find out the lateral forces due to wind on a light pole (tapered profile) and provide suitable support for the same. Wind was…

I need to analyze existing tapered members in a PEMB frame where the members have different flange thicknesses, for example, the front and rear flanges are different thicknesses. Using an ITM section, is this possible? or do I need to create a shell…

Dear All, We are using STAAD.Pro CONNECT Edition V22 Update 6. We are unable design tapered/Built-up members in Eurocode 3 EN 1993-1-1 2005. Can you please guide us, how to design tapered/Built-up section in Staad. Using Eurocode 3 Refer…

I am designing a moving steel deck, and have represented the steelwork alone in the attached STAAD model. The ends of the main longitudinal beams are tapered and fixed into a lateral UB which ties all the ends together. I am getting a utilisation…

1) Design check by IS Code 800-2007 LSD fails gives result of Bending Ratio = “INFINITY”, which passes with AISC 360-10 ASD Ratio 0.44! Also IS 800 code output does not give any ratio in both major, minor axis! 2) Is this 12 mm Flange thickness is critical…

Dear Team Bentley, I have a curious question to ask regarding Member Size in Properties for Tapered Sections. My queries as below: 1. Why STAAD show Tapered Section with 1,2,3 etc. instead of Member Sizes like (d1-d2)xtw+2*(b1-b2)xtf1/tf2 like this…

Hi everyone, It is very weird that I am getting different utilization factors every time I run the analysis (The software picks different forces values at the tapered element) and for some reason, all sections have the same utilization value. Could…

Hi there I have a steel model with number of Tapered I section profiles. I want the Select Optimise to use from this list and and come up with least weight structure. This is using IS 800. Can someone help. Thanks Ashutosh

the below code uses GetSectionPropertyValuesEx which is not working . refering to the previous thread https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/119259/member-properties-for-web-tapered-sections-in-open-staad "prop" array…

Hi, I am designing a structure containing tapered members (ITM sections). When I try to run the design process, the "Use MBMA special considerations (DG 25)" is greyed out in the Design option interface. Is there any steps to actually turn on the…

Hello Everyone, I designed a Tapered Built up section in STAAD as per AISC 360-10 and the same member as per AISC 360-16. The member failed in AISC 360-16. Can anyone help on this? Can someone explain me how STAAD calculates Elastic section modulus…

Hi everyone, I am using SS5 10.65, I have tested 2 cases of tapered section within AISC 2005 ASD/LRFD. Case 1: Tapered section is a straight member, it means start depth is equal to end depth. 1 TAPERED 0.516 0.004 0.516 0.175 0.008 0.175 0.008…
