The results of an experimental program, devoted to the investigation of the structural behaviour of precast RC beam-column nodes under cyclic loading are described. The experimental activity is a part of a research campaign developed to evaluate the seismic behaviour of a multi-story precast concrete system with cast completed in situ. The experimental tests have been carried out by imposing cyclic quasi-static vertical displacements at the extremities of the beams. An axial load on the column is also applied, simulating the vertical action given by the permanent loadings. The hysteresis response and the strains of the steel bars (longitudinal reinforcement and stirrups) within the node are recorded. The ductility of the connection and the cyclic strength degradation at prescribed displacement values are also evaluated from the experimental data.

Abstract

The results of an experimental program, devoted to the investigation of the structural behaviour of precast RC beam-column nodes under cyclic loading are described. The experimental activity is a part of a research campaign developed to evaluate the seismic behaviour of a multi-story precast concrete system with cast completed in situ. The experimental tests have been carried out by imposing cyclic quasi-static vertical displacements at the extremities of the beams. An axial load on the column is also applied, simulating the vertical action given by the permanent loadings. The hysteresis response and the strains of the steel bars (longitudinal reinforcement and stirrups) within the node are recorded. The ductility of the connection and the cyclic strength degradation at prescribed displacement values are also evaluated from the experimental data.
