摘要：

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 investigated by introducing a simplified analytical model. The model is then validated through Finite Element analysis. Finally, the possibility of optimizing the joint geometry and mechanical performances using novel metal 3D printing techniques (such as Wire-and-Arc Additive Manufacturing) is briefly presented.
