Abstract

This paper presents an analytical study that focuses on the development of

a parametric equation to predict the joint shear strength. In this analytical study, a

database containing geometric properties, material strengths, configuration details

and test results of reinforced concrete beam-to-column connection subassemblies

tested under cyclic loading is established. Then, based on the experimental results,

parameters affecting joint shear capacity are determined. The most influential

parameters are selected and an equation to predict the maximum joint shear

strength is formed. The developed equation includes parameters that take into

account the effect of eccentricity, wide beams, transverse beams and presence of

slab on the seismic behavior of the connection region, besides the key parameters

such as concrete compressive strength, effective joint width and joint transverse

reinforcement ratio. The maximum joint shear strength vales obtained by the

proposed equation are then compared with different code approaches and the

comparison results are discussed.
