Abstract

The results of an experimental program, devoted to the investigation of the structural behaviour of a precast RC beam-column node under cyclic loading, are described. The experimental activity is part of a research campaign developed to evaluate the seismic behaviour of a multi-story precast concrete system completed in situ. The experimental tests have been carried out by imposing cyclic quasi-static transverse displacements at the end sections of the beams. An axial load on the column is also applied, simulating the vertical load given by the permanent actions. The seismic performance of the node is experimentally studied. The hysteresis response and the strain profiles 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.
