The paper presents the experimental characterization and topology optimization of dissipative panel-to-panel connections of precast structures. The investigated connection devices consist of steel plates with multiple slits and openings, which define a set of elementary beams working in parallel. The shape, size and location of the openings determine the hysteretic behavior of the device. The paper summarizes the main results of experimental tests carried out on four different configurations of the device and presents an evolutionary structural optimization technique that allows to define both shape and topology of the elementary beams in order to increase the energy dissipation capacity of the connection.

Abstract
The paper presents the experimental characterization and topology optimization of dissipative panel-to-panel connections of precast structures. The investigated connection devices consist of steel plates with multiple slits and openings, which define a set of elementary beams working in parallel. The shape, size and location of the openings determine the hysteretic behavior of the device. The paper summarizes the main results of experimental tests carried out on four different configurations of the device and presents an evolutionary structural optimization technique that allows to define both shape and topology of the elementary beams in order to increase the energy dissipation capacity of the connection.| File | Dimensione | Formato | |
