embeded 2D frame analysis

[xyont]

hello,

continuous beam, 2D truss/frame are common problem in mechanical or structural design.

it seems to be useful when CalcPad can do such as calculation inside, may using available solver (FEAlite2D) is possible.

greetings,

Hi @xyont, thank you for sharing that. Seems to be a nice little frame analysis library.
We have our own FEA software in Proektsoft that has been developed for 40 years with 3D frames, plates and shells. But it is paid and proprietary and we are not going to make it open source.

However, structural analysis are not comfortable to be performed in a coding format like Calcpad. What we need is a GUI with full drafting capabilities as we have for the other software of ours. Also, structural analysis is a completely different kind of a software and it is not something we can stich it just like that to Calcpad. It goes far beyond its main purpose. Just the opposite, Calcpad is something that can be embedded into FEA software to make little design worksheets that reads from the model input data and analysis results.

thanks @Proektsoftbg for explanation, i mean less complicated than common 3D structural analysis software, even Tekla Tedds 2D frame features with fully graphical interfaces.

provide an input of problem definition by parametric approach, than shown plot all or some requested results.

this can be useful since not all problem in designing are complex enough, e.g continuous beam, single storey frames and gable/arch, joist truss, footing by spring support, retaining wall and box culvert.

Yes, I agree, but adding a frame analysis program with GUI to Calcpad is not just a one weekend task. It is a project that is even bigger than Calcpad, even for 2D frames, beams and trusses.

The same idea occurred to me some years ago. I started a project called Drawpad that included drafting + Calcpad functionality. It allowed to draw objects from math expressions and build parametric drawings or models in this way. That is how you could write and read not only analysis models but also to automatically generate CAD details, based on design results.

However, the project was abandoned, because of the lack of resources, time and people to develop it further. It is even difficult with Calcpad, because it already requires much more time and work that I can handle alone.

no GUI is required only sketch and input of problem, n example of gable frames above can be parametrized by geometry and loads: spans, column height, roof slopes and section properties of members) uniform load & point load to be consider.

this model can be expanding to another module, for example have two or more spans.

Take a look at this software i shared with Ned in this Topic: #56 It's a language for structural analysis, maybe this can do what you want. Em seg, 20 de fev de 2023 11:44, suyono nt. ***@***.***> escreveu:

right, i was seeing the threads before.

however, it seems 2D frame/truss library embeded is a different things, for example Tekla has full 3D structural analysis called Structural Designer but still embeded 2D frame analysis in their Tedds stand alone application similar to Calcpad.

Tekla Tedds are too complex, table values based user input to define arbitrary 2D structural analysis. i'm thinking in a different ways inside Calcpad, this can be parameterized by sub-programs.
