Abstract:
Reinforced concrete (RC) beam-column knee joints are intrinsically distinct from the traditional RC interior and exterior joints. The RC knee joint has two distinct load resistance mechanisms. Its shows different behavior at the time of reversed cyclic load for closing and opening. Given the many distinct variations in the behavior of shear strength in RC knee joints, the main design codes in the world do not provide any specific design RC knee joint. This is because there is no profound research on the knee joint. An investigation for predicting the shear capacity of reinforced concrete (RC) knee joints under opening and closing moment has been proposed in this research. Experimental data in the literature were used to test the exactness and reliability of the proposed model. The proposed model could forecast with good accuracy the experimental response of poorly defined RC knee joints under opening and closing moment. Parametric experiments have been performed to demonstrate the profound influence of different geometric and material properties on the RC knee joints. A method will render the model ideal for practical applications.
