Structural engineering programs

[Johnh]

I'd like to test the water to ask if anyone here is interested in programs for structural engineering? I'm thinking of working towards a 'Pac'

I've written quite a number of these over the years, for various calculators, and also a number of spreadsheets which would be simple enough to implement on a calculator.

My current Interest would be for a 15C, but it may be better to work with something more generally versatile such as a 42.

Anything for a calculator needs to be fairly simple and direct, because if not, then a calculator isn't the right tool.

So far, for my Hp15C-Ce I have a nice little program to work out major-axis section properties of a general symmetrical I section or box section, or a general circular hollow section

For Hp35s, I have this for Assymetrical sections too, for which the ability to have Alpha prompts is very useful.
Also, for Hp35s I have singly or doubly reinforced concrete beams, and concrete columns in bending and axial. But sadly, this general great calculator turns out to be useless due to the many ways in which it loses all its data with no option to back up.

Years ago, I also had the above worked out for BASIC on a Casio pocket computer, and also a TI58. In BASIC, I had some general continuous beam analysis, which used Moment Distribution

Steel beam and column calcs is another one I've written several times. With these and the concrete programs, they have to be written to follow a code, and that depends which country it's for, and codes change too.
