The present work explores the use of a curved hysteretic steel device, known as Crescent Shaped Brace, to strengthen pinned beam-column connections in order to obtain semi-rigid joints. The kinematics and mechanical behavior of the semi-rigid joint is inves-tigated by introducing a simplified analytical model. The model is then validated through Finite Element analysis. Finally, the possibil-ity of optimizing the joint geometry and mechanical performances using novel metal 3D printing techniques (such as Wire-and-Arc Ad-ditive Manufacturing) is briefly presented.

Abstract
The present work explores the use of a curved hysteretic steel device, known as Crescent Shaped Brace, to strengthen pinned beam-column connections in order to obtain semi-rigid joints. The kinematics and mechanical behavior of the semi-rigid joint is inves-tigated by introducing a simplified analytical model. The model is then validated through Finite Element analysis. Finally, the possibil-ity of optimizing the joint geometry and mechanical performances using novel metal 3D printing techniques (such as Wire-and-Arc Ad-ditive Manufacturing) is briefly presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
