Iteration among different sections

SFares — Sat, 31 May 2025 18:59:01 GMT

Hello,

I have attached Mathcad prime 9 document. I'd to iterate thru sections and select the proper section size that satisfy certain design criteria. On page 3, the TC sections are listed as shown below

The member is selected manually until the interaction ratios (IR) on page 6 (shown below)

and interaction ratios on page 11 (shown below)

are all equal or less than one.

i Just want to automate the process.

Thank you for your assistance!

Sam

Hi Sam,

One way is to use the match function with the less than modifier.

Cheers

Terry

Hello Terry,

The section sizes are listed in TC list. There are about 19 sections labeled H#. I’d mathcad to loop from the top of the list until it finds a section that will make the ratios listed in variable IR shown on page on pages 6 and 11 less or equal to one. If you look at IRtcpnl, some of the values are more than one. This the section TC: H30-CRC is not large enough. The next size might be strong enough to satisfy that criteria of making all the ratios equal or less than one.

Thank you!
