Our calculator of choice is the HP48GX programmable calculator and I have written several programs for it to aid us in our work. These programs and many others are available from www.hpcalc.org. We posted two items there, the first is a text document outlining the procedure of how to develop programs that use metric/imperial conversions. You can download it from www.hpcalc.org/math/misc/fiscalc.zip

The second is a collection of programs that would be useful for steel detailers, including right triangle solutions, oblique triangle solutions, segment solutions, hip and valley calculations, parabolic cambers, and steel connection details such as sloping beams and skewed shear plates, and weight calculations. Included is a 33 page manual written in WordPerfect8 which not only describes every program but also gives step by step instructions on how to load the programs into an HP48GX. The HP48G can accept these programs but with reduced functionality

You can download it from
www.hpcalc.org/apps/misc/steel20.zip. All programs are as is, comments are welcome but we no longer offer support.
