Combination Ratio

A couple of times in the design the combination utilization percent is lower than the individual tension or shear utilization percent. Is there a increase in combination ratio? if yes, how much? Is there

combination,tension and shear

Hi Ruchin,
 
The combination utilization is calculated using either the tri-linear equation or the parabolic equation. To see the equations and how tension and shear interact, see page 347 of the PROFIS Engineering Design Guide

Cheers,
Emily

Thank you Emily. I did not realize there was a design guide available for HILTI profis. This is going to be very helpful. Thank you for sharing.
