Abstract:
An expression to estimate the unit shear strength of reinforced concrete columns is developed and calibrated using results from 62 tests on reinforced concrete members with rectangular cross sections. The effects of longitudinal reinforcement, transverse reinforcement, and axial load on shear strength are estimated with a simple formulation based on the Mohr-Coulomb failure criterion. It is concluded that shear strength increases at a decreasing rate with increases in transverse reinforcement and axial force.
