Finite element model for curved reinforcement in concrete structures

This paper presents a numerical model applied to the plane reinforced concrete structures with curved reinforcing bars. The paper presents the expressions used for modelling generally curved bars embedded in a concrete eight-node Serendipity element. The reinforcement is given in a global coordinate system separately od the finite 2D element mesh. The transformation of the global coordinates of renforcement points into global coordinate system of the concrete finite element was performed using Newton iterative method. Finally, this model was applied to several actual examples.
