SLIP OF STEEL BARS IN CONCRETE JOINTS UNDER CYCLIC LOADING

This paper presents a closed form solution for computing the slip and its distribution along reinforcing steel bars anchored inside a beam-column interior or exterior joint and subject to generalized boundary steel stress excitations. This model can be used in conjuction with a joint model to describe moment-rotation hysteretic behavior of interior or exterior beam-column joints under generalized load excitation. The model is based solely on a knowledge of the monotonic bond stress-slip characteristics of confined concrete. The main advantages of the proposed model, under which much cumputational effort can be saved are listed. The proposed model can be used to predict the anchorage characteristics of prestressing steel strands inside beam-column joints under generalized excitations by only its bond-slip relationship under monotonic loading.
