Steel Frame Analysis (suffer torsion)

AI Thread Summary
The discussion focuses on analyzing steel frames subjected to torsion, highlighting the need for effective calculation methods. It suggests that finite element analysis (FEA) is a practical approach for determining member forces, although hand calculations can be tedious. A recommendation is made to use the free software Calculix for FEA. Additionally, the user seeks references or books that provide engineering equations for solving torsion in steel frames. The conversation emphasizes the importance of understanding both computational and analytical methods for structural analysis.

Hi every one.

As Steel Frame Manuel mostly discribe the force analysis in vertical loading,

I wonder how can i solve the following case, a member that suffer torison.
Is there any reference book you might suggest me to read ,too?

Thanks for your kind help.

The attached are the cases I would like to calculate:

It appears your applied moment transfers through the green apparatus to become (the negative of) the blue force couple shown in your diagram. Therefore, you have loads applied on your structure, and you would use finite element analysis to solve for the member forces in your frame. Performing finite element analysis by hand calculations would be very tedious and is generally impractical. You could instead perhaps try Calculix[/color] for free.

Thanks for suggestion.
I know the frame can be solved by FEA, however I wonder is there any method to solve it by engineering equations.

Is there any books that have such kind of example??

Thank you very much for your kind help.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
