Abstract
This paper presents a new analytical model formulation for simulating the lateral load–deformation response of reinforced concrete columns with deficient lap splices. The modeling approach proposed involves implementing bond stress vs. slip springs in the formulation of a fiber-based flexural macro-model. The analytical model directly reflects the influence of local bond slip deformations on the lateral load–displacement response of a reinforced concrete column under cyclic lateral loading, via consideration of local coupling between flexural deformations and slip deformations associated with either splitting or pullout bond failures, along the lap splice region. The flexible formulation of the model allows investigating the influence of using smooth reinforcing bars, presence of hooks, and strain penetration effects on the lateral load behavior of a column. The modeling approach presented is believed to be a significant improvement, towards realistic consideration of the influence of bond slip deformations and anchorage failures on the seismic response of reinforced concrete buildings.
