Introduction to LRFD, Loads and Loads Distribution

Introduction to LRFD 1-8 Resistance Factors (Article 6.5.4.2) Resistance factors, φ, for the strength limit state shall be taken as follows: • For flexure φf = 1.00 • For shear φv = 1.00 • For axial compression, steel only φc = 0.90 • For axial compression, composite φc = 0.90 • For tension, fracture in net section φu = 0.80 • For tension, yielding in gross section φy = 0.95
