In this paper, the interaction between shear and tension forces on typical holdown connectors used in Cross Laminated Timber structures was investigated by means of experimental cyclic tests. A new experimental setup was designed in order to test typical holdowns prescribing a value of shear deformation and then applying a cyclic loading in tension to the connection. Specimens subject to five different levels of prescribed shear deformation were tested and the results analyzed. The test results in terms of strength, stiffness, energy dissipation, strength degradation and ductility are presented here and critically discussed. Experimental values of load-carrying capacity and stiffness are also compared with those obtained according to code provisions.

Abstract

In this paper, the interaction between shear and tension forces on typical holdown connectors used in Cross Laminated Timber structures was investigated by means of experimental cyclic tests. A new experimental setup was designed in order to test typical holdowns prescribing a value of shear deformation and then applying a cyclic loading in tension to the connection. Specimens subject to five different levels of prescribed shear deformation were tested and the results analyzed. The test results in terms of strength, stiffness, energy dissipation, strength degradation and ductility are presented here and critically discussed. Experimental values of load-carrying capacity and stiffness are also compared with those obtained according to code provisions.
