A Predictive Regression Model for the Shear Strength of RC Knee Joint Subjected to Cyclic Load

Abstract

Reverse cyclic loading is applied to the RC knee joint, which causes the knee joint to experience either opening or closing moments. To calculate the joint's shear strength, an effective nonlinear model is created herein. The shear strength of the knee joint either in opening or closing is predicted by two distinct and practical equations developed utilizing a regression-based methodology. The effects of material and geometric factors are taken into account, including the compressive strength of concrete, the joint aspect ratio, and reinforcement strength. The proposed equations are developed using a statistical analysis of a database containing 61 experiments. The proposed equations are statistically evaluated and examined with the models that were earlier put out. Thus, the suggested models can fairly accurately forecast the shear capacity, which makes them ideal for usage in real applications.
