A Constitutive Modeling of the Mechanical Behavior of a Reinforced Pier Involving Nonlocal Interactions
A linear viscoelastic nonlocal constitutive model is presented for the inplane mechanical behavior of a pier reinforced with arbitrary spacing of steel bars along two orthogonal directions. Actual reinforcement is realized by a discretization of a continuous fiber distribution in the isotropic homogeneous matrix material.The influence on the stiffness matrix of the number and distribution (in the sense of second moments) of reinforcing bars and that of nonlocality is quantitatively obtained. The model predicts an experimentally consistent hysteretic nodal force-displacement relation.
