Shell shear reinforcement

Use the Shell shear reinforcement tool to manually draw shear link regions on concrete shell elements.
You define the region geometry and set spacing values directly in the tool palette, giving you full control over where and how shear reinforcement is applied.


Tool palette​

Manual design opens a tool palette where you define how shear reinforcement is created and applied.
