- •
Web slots reduced shear strength of tested channels by 50–71%.
- •
The shear strength reduction depended on channel thickness and depth.
- •
Slotted channels demonstrated more ductile behavior when compared with solid ones.
- •
Slotted channels exhibited post-buckling strength due to tension field action.
- •
Tentative equations for shear strength of slotted channels were proposed.
