Unformatted text preview: 1 Term Project Shear Slide 2 Term Project Shear Slide ACI & AASHTO • ACI and AASHTO have different approaches (and notation) for the design for shear • ACI uses an empirical, and simple, approach based on a 45 degree angle truss model. Factor Φ = 0.75. • AASHTO follows the latest developments and uses an approach based on strain compatibility and equilibrium (modified compression field theory). The critical diagonal crack does not have to be at 45 degrees. Factor Φ = 0.90. • In our term project we will use a simplified version of AASHTO and will set the angle of the diagonal crack at 45 degrees 3 Term Project Shear Slide Effective Girder (Beam) Dimensions • For shear design, effective dimensions are used to explicitly account for shear flow through a section. – LRFD 5.8.2.9 • The effective shear depth, d v , is the distance between the resultant compressive and tension forces....
