Can't find LGSI handbook 1

[Joe117]

Anyone know where I can find a LGSI Framing Systems Design Handbook? Been seeing on threads there's a good one from 1990. Been hoping to find something on z purlins that is similar to the flexure tables from AISC handbook.

Z-girts seem to have disappeared from the generic catalogs. You may be best served by using supplier specific information like this (Canadian unfortunately): Link

The Canadian steel handbook actually does have a section useful for the preliminary design of Z-Girts. The units are obnoxious to those of us brought up stateside but perhaps this will still be of use to you anyhow.

Slide Rule Era has a lot of good resources for old reference material.

Thank y'all. Also just found some in Appendix B from Neuman's PEMB book. Really wish all good info/tables were free.

There's a very inexpensive program called CFS (Cold Formed Steel) that you can use to design and check this stuff. Understands and works with lapped z-sections or any section you make up.

I think it's about $150 per year. Well worth it compared to your time trying to hand calc 20 different buckling limit states for every shape. Actually just checked and they have a free version with limited functionality.

I second the recommendation of the CFS software.

American Iron and Steel Institute does publish a Cold-Formed Steel Design Manual, my 2002 editions has Z-member span charts (similar to AISC), I attached an example. The current edition is 2017, I do not know if they have continued to publish the tables.
