Hello Members,
Could any one assist me in getting correct reaction forces at anchor point while using compression support.
I having an bracket system with single anchor point which is fixed on the wall. apart from anchor point i assigned compression support, since the bracket is anchored in the vertical wall.
1. When i assign support only at the anchor point without assigning any compression support, my reaction forces (Tension Value) is almost correct
2.. When i assign support at anchor point + compression support, my reaction forces is not getting correct and the value showing compression force.
Bracket.std
Staad file is attached. Could anyone pls assit in this to get correct reaction forces at anchor point
Advance Thanks
When using compression only springs, you need to change the LOAD COMBINATIONs to REPEAT LOADs
Following wikis should help

Hello Sye,
Thanks for your support. I reviewed the link which you suggested and modified the model accordingly with REPEAT LOADs, but still i dint get the support reactions of Tension value at Anchor Point. Its showing compression value at anchor point.
Model is attached. Pls recommend what is the possibility to get Correct Tension Value at Anchor Point.
Advance Thanks.BRKT.std

Hello Kris,
I agree with your point. But how to get tensile force @ Anchor point, My program output showing only compression force @ anchor point and not tensile force.
Now next step, how do i design my anchor without tension force from output.

Thanks in Advance.
Go into the editor, replace the command SPRING COMPRESSION with SPRING TENSION, and check if the response matches your expectations.
