Welcome to the Ellis MFG Co. National Design Specifications Allowable Load Calculator for Ellis Shores.
Start by entering the desired shoring height in feet. Next, select the desired Ellis Shore Clamp Type. Step three, select the appropriate lumber species and grade types. If you would like to enter the lumber properties manually you can select "Custom" under species and enter Fc*, Emin', and Fb'. Once all configurations have been entered click "Get Load Data". The calculator will return the recommended allowable load capacity for the given shoring specs. All shore load data compiled with 2015 National Design Specifications from The American Wood Council.
While the NDS Allowable Loads calculated in this app are useful for theoretical testing we have found that actual destructive loads are up to 6x more than the loads reported in this app. You can find actual safe working loads for a few variations of shores at the bottom of the product page.
