Analytical Modeling of Bonded Bars under Cyclic Loads

Abstract
A new modeling technique for predicting the behavior of deformed bars anchored in concrete is developed. In the model, the bond between steel and concrete is simulated with discrete springs that connect the bar to concrete along the anchorage length. The simulation technique is based on the displacement method of analysis. Unlike other approaches, the new model does not require iterative solution of the governing nonlinear equations. This technique involves the construction of the tangent stiffness matrix of the anchorage for use in an incremental solution algorithm. The model is thus very time‐efficient for computer analysis. The proposed model is used for simulating the behavior of bonded bars with common types of boundary conditions. The analytical results are compared with results of monotonic and cyclic tests. The model can be used for efficient idealization of anchorages in analytical studies of structural subassemblies and complete structural systems.
