Combined beding with tensile axial load is common in walls of silos and tanks and occasonal in other structures. However, for ultimate strength design, codes and handbooks have considered only compression with bending or small axial tension with bending. This paper shows five cases of combined tension and bending. Formulas are developed giving required steel areas for each case. Strength design (ultimate strength) is used. The resulting formulas involve only the already available theory used for flexural members under ACI 318-71.
