Free Structural Frame Calculator | Cloud Structural Software

This free online frame calculator will generate and find the bending moment and shear force diagrams of a 2D frame structure. The free version of this powerful engineering tool allows users to input frames with a maximum of 3 members with applied point loads and moments for 2D frame analysis. Users can also control settings such as units, display settings of framing members and nodes etc. by simply clicking the 'Settings' button. This free online frame calculator will only allow certain features (3 members, 2 supports, 2 point loads and 2 distributed loads only). More features are available in the paid SkyCiv Frame Calculator, such as deflection and stress results, as well as unlimited supports, members and loads. The frame calculator offers an easy to use structural analysis program which allows users to apply loads to a structure and interpret the results in an easy and clean diagrams. Not what you're after? SkyCiv offer a range of other structural analysis software such as our SkyCiv Beam and SkyCiv Truss calculators!

More Free Tools Available

Here at SkyCiv, we continue to deliver valuable tools and resources that will aid in the work of structural engineers. We have a long list of other free and easy to use tools for you to check out. Check out our free design section reference for obtaining the geometric properties of standard steel or aluminum sections. Check out our free beam design module for analysis of simply-supported beams. You can also check out our free truss calculator for quick analysis of 2D trusses. For typical shapes of non-standard sizes, the free moment of inertia calculator is a good resource to obtaining their geometric properties.

Hey all, just to let you know, it is the second day that I’m trying to use your feature but it doesn’t work. A server problem message appear. …:)…see ya

  Hi Alan. That’s strange because it seems to be working just fine from my end. The server is definitely available right now — there is either something wrong with your setup or your browser. Please ensure you have added a support (as it doesn’t look like there is one as well as a section). Although it should mention the error if it was that simple. It might also interest you to know that we have a free beam calculator: http://bendingmomentdiagram.com/free-calculator/

    Hello Paul,
    Just to let you know, still the same problem, I even tried in another browser, but still doesn’t work….

      Hi Alan Sorry for the issues you’re experiencing. Let’s get to the bottom of this – I’ve emailed you. Hope to hear from you soon.

For frame section at least 3 members is needed..but in free calculator..2 members only allowed..so worst.please make it as three members
- Paul
  
  Hi there. Many frames have two members like this one.
  - Vengatesh Hari
    
    At least make it as 3 member in free calculator.it would be very helpful for students.
    - Paul
      
      Two members is sufficient for many problems. Maybe you should have a look at SkyCiv Frame as it can do 10 members! It comes with the SkyCiv Student account along with SkyCiv Truss and SkyCiv Beam.

    This unhelpful reply made me not want to give you my money, I will now not buy this product.

      Hi Christy. The free calculator can only do 2 members at this stage. I showed a frame scenario which has 2 members as it may help others to see that it can handle a range of scenarios. Sorry if it cannot handle your particular analysis but this is why we have SkyCiv Frame. More members puts more stress on the server and paid members get priority for this. Try out the demo account as there are some pre-loaded files in there so you can see how it works.
