Concrete Shear Wall to AS3600

Verified by the CalcTree engineering team on September 24, 2024. 
This calculator allows the user to assess the structural integrity of concrete unbraced walls. The calculation will identify the design capacities of concrete columns to meet axial, flexural and shear design requirements to Ultimate Limit State (ULS) methods. 
This Calculation has been written in accordance with AS3600:2018
