Any thoughts on what one should add into something like this and make it a top notch piece of software. The intended audience is residential designers, engineers and other design professionals.

I know I am recreating the wheel a bit here when much more complex pieces of software already commercially exist ie. Mitek, Alpine etc However, as some of you may know these vendors do not allow their software into the hands of architects or engineers, they only sell or lease to truss manufacturers.

I find this a bit troubling since the vast majority of residential trusses are designed with one of these softwares and it is essentially a black box to the design industry. My intent is not to circumvent the usual process of truss design and manufacture by the truss plants but to give other design professionals a tool to help estimate, check and create different scenarios for their truss needs.

Once I get this project far enough along where its output is actually useful, I will try to package it into a full app and then make the binary and full source freely available and hopefully enlist the help of others in its continued development. The statics equations for the double fink got really long and sure enough I made a small typo in the code a misplaced dollar sign in front of one of my variables, perl code.

So for about 3 hours I scratched my head trying to figure out why my internal checks were not adding up. Finally I remembered I still had and old demo version of "Working Model" on an install disk so I mocked up the truss in that with all the correct forces and dimensions as a independent check. Helped lead me right to the typo. Also really cool to see that my equations checked out perfectly. It never fails to amaze me how some simple math and a few carefully placed vectors can model real world systems.

Anyhow, the double fink is finally up, that one was fun. Wow, this is pretty ambitious and I would love to see it work. I'll check it out when I got more time.

I think some of the proprietary nature of the MFG software has a lot to do with the truss plates themselves and partial fixity at the joints. I could be wrong here but when I get trusses analyzed by contacts at the plants, their values always differ a bit from mine in not always subtle ways.

They also put fun joints with "sliders" and "wedges" into places where they need to raise heels and such. Sometimes odd joints - not at nodes Always changes ideal behavior. The Truss solver can handle extremely large structures of more than 10, members. So if you have a larger structure, simply upgrade and you can use the full S3D program for all your analysis needs. A truss is typically a triangular structure that is connected by pinned joints such that they mainly incur an axial force see what is a truss.

This above tool will allow you to run truss analysis on any of these trusses to get the internal member forces. There are a number of different types of trusses , including pratt truss, warren truss and howe truss; each with their own set of pros and cons. There are some limitations on the above truss calculator that can be achieved through full structural analysis software.

Get more results such as bending moment and shear force diagrams , get more members and loading types area loads, distributed loads and self weight and model in 3D.

Upgrade to a professional plan to unlock full features. Powerful hand calculation modules that show the step by step hand calculations excluding hinges for reactions, BMD, SFD, centroids, moment of inertia and trusses!

Add as many supports, loads, hinges and even additional members with SkyCiv paid plans. For the created structure, you can enable view node, beam, member, and section names and draw permanent, imposed, wind, and snow loads. The full version of this software is paid, but you can use its demo version free of charge. The demo version comes with many feature restrictions, e. Still, the free version comes with various desirable tools to draw and analyze truss structures.

This whole procedure is divided into two primary steps:. From Analysis menu, you will find various tools for different analysis and evaluation purposes.

These tools include Mounting structure mounting with cut-pieces , Automatic Design automatic designing of structure, timber sections, and nail plates , Pricing Calculations calculation of price of given structure , Quotation general geometric properties and pricing information , etc. It provides four types of analysis reports:.

Other handy tools provided by this software include Distance Measuring, Restore automatic modes, etc. Also, the analysis report can be printed as PDF too.

Like other software in this list, it also lets you design truss and calculate internal forces and stress along members. This can be done in Model tab. There are two more tabs present on the main interface named Deformed and Axial. The former one displays deformed shape, while the latter one shows axial force diagrams. After creating truss structure, you can go to Calculate menu and click the Run Analysis option.

At the right panel of the interface, you can view Results. These Results include:. Simple Truss Solver , as the name suggests, is a free truss design calculator software. It lets you draw a truss structure and calculate truss problem. You can modify these existing projects or start with a new one.

It supports multi-window interface, so you can work on multiple projects in different windows at a time.
