dc.description.abstract | In this work we follow a multiscale methodology to characterize the structural performance
of post-tensioned steel fiber-reinforced concrete dry joints. At the material level, we use an
experimentally validated lattice-particle model whose input parameters are the properties of the
di erent phases themselves (i.e., mortar, aggregates, fibers) and mixing information. This model
is used to obtain the mechanical properties used in the structural-level simulations of the joints
in terms of constitutive laws. The structural analyses are performed using the concrete damage
plasticity model, which allows us to quantify the e ect of fiber addition on the shear strength of
the dry joints and their ductility. Our simulations agree well with other macroscopic models in
the case of plain concrete and show, once again, that the American Association of State Highway
Transportation O cials (AASHTO) code overestimates the nominal shear capacity of multiple-keyed
joints. Regarding the fiber addition, we observe that it promotes an important increase in the
shear capacity, but the prestress level is still more relevant in this sense. Based on our simulations,
we propose an updated shear capacity estimate accounting for the fiber volume fraction. Finally,
a clear increase in the ductility of the joint is observed when the fiber volume content is increased. | es |
