Lorenzo,
This is nicely done and easy to look at, something lacking in most files. For design though, a section is normally selected based on strength or stiffness, sometimes its un-braced, sometimes (but rareily) its not compact. What would be of great value is to take a little time and add columns after the section column showing the strength, unbraced lengths compactness and I. This could be added by taking a lot of time to manipulate the database using a program, or just sitting down for an afternoon and copy the information from the appropriate ASIC table. Then searching for qualifying sections is much easier, and for most problems, the design is actually done upon selection. You could import the revised data table and use mathcad functions as needed to search, or search by scrolling, or do something more elaborate.
Again, nicely done and generous of you to post.
Wayne
