Method for Shear Strength Calculation of RC Interior Beam-Column Joints

Abstract

Several RC beam-column joint shear strength calculation methods incorporating assumptions related to the concrete compressive strut and the effective compressive strength have been investigated. However, these methods did not consider the inelastic behavior of columns and beams around beam-column joints. Therefore, a method that incorporates inelastic behavior of columns and beams was developed for theoretical calculation of beam-column joint shear strength. This proposed method determines the compressive strut width of concrete at joints as a function of the compressive regions of columns and beams at a critical section. The calculation results obtained with the proposed method were confirmed to agree well with the experiment results.
