Abstract: This paper presents a new interface model to simulate the cyclic bond-slip behavior of steel reinforcing bars embedded in concrete. A multi-surface plasticity formulation is used to model two major inelastic deformation ...

Abstract: A new interface model to simulate the bond-slip behavior of reinforcing bars is presented. The model adopts a semiempirical law to predict the bond stress-versus-slip relations of bars, accounting for the bond deterioration ...

Abstract: Prestressing tendons made of fiber-reinforced polymers (FRPs) are a promising alternative to conventional steel tendons in prestressed concrete structures owing to their corrosion resistance. However, the shear strength ...

Abstract: This paper presents a numerical parametric study to examine the structural response of drilled shaft footings (pile caps) presenting different design characteristics, which have not been studied in depth in previous ...

Abstract: This paper presents a practical, accurate, and reasonably conservative procedure for the design and analysis of drilled shaft footings, also referred to as pile caps. A database of drilled shaft footing tests was compiled ...
