Flexure wood

WebConsider two safety limit states — shear and flexure. The demand / capacity relations for shear are shown. ASD modifies the capacity with the C Dfactor for load duration. The LRFD capacity equation includes the time effect factor λ and the resistance factor for shear φ v. Note that factored LRFD loads are used in calculating the demand. WebNov 8, 2024 · 3.
