Cracking moment reinforced concrete beam formula

The 2018 revision of the AS3600 Concrete standard includes major revisions for areas including phi factors, shear, deflection, rectangular stress block, and shrinkage/creep. In this webinar, ClearCalcs lead engineering developer Brooks Smith discusses some of these key changes, and runs through the design process for a concrete beam design.

New Avenue of Achieving Ductility for Reinforced Concrete Members ...

For reinforced concrete (RC) members, this curvature depends on the tensile strain of the reinforcement and the compressive strain of the concrete. As concrete is a brittle material with little ductility, RC members achieve ductility and adequate deformation capacity mainly through the tensile straining or yielding of the reinforcement.

Reinforced Concrete Ductbank Under Building Footing

Related to a concrete encased and rebar enforced conduit ductbank passing 3' or so under a 5000 psf footing, it seems like to me there would be little risk of crushing this ductbank. If my concrete is rated for 3000 psi, I would think compression strength would be more than enough to handle this load. Maybe there are complications with tensile ...
