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. |
