Typical shear walls and diaphragm ☑ 4.1 Shear Wall Desigr in-plane shear lo Typical failure modes in nailed connection• A shear wall or diaphragm 1) a flat or curved plate-type structural assembly ; 2) resist lateral loads such as wind or earthquake loads. • Shear walls carry: lateral shear/racking forces & vertical forces • Diaphragms (roof/floor) carry: shear forces & bending moments diaphragm shear wall 37 Typical shear walls and diaphragms 38 Shear wall and diaphragm action under lateral loads 39 4.1 Shear Wall Design A few facts: • Framing members form the skeleton; • Shear load is applied to framing first and then transferred to panels through nailed connections; • Panels carry in-plane shear load; and • Nailed connections normally govern shear wall capacity 40 41 Typical failure modes in nailed connections h b Vf Vfh/b Vfh/b 42
