Wire Sling / Cables in Conveyor Design

adnan_muharam — Sat, 01 Jun 2024 13:23:39 GMT

Hello Everyone,

Currently I am planning to reinforce the existing conveyor building with the addition of wire slings / cables. How to do that correctly using RSA? I have done several ways by creating new sections, tension members, creating cable sections. But still get maps member ratio that overstressed.

Thank You

Hi @adnan_muharam

Before analyzing stress ratio or other, you must correct your model as it’s a non linear structure, then:
- Merge all wires sling and tension rods
- Apply cable function to wire sling
- Set tension rod as tension only truss
- Delete members (LE 100x100x13) joining tension rod bars (Before analyzing stress ratio or other, you must correct your model as it’s a non linear structure, then:

You may then analyse results according to your code
