The Crescent Shaped Brace (CSB) is a new steel dissipative device recently proposed by some of the authors within the context of Performance Based Seismic Design (PBSD). Contrarily to the conventional concentric stiff diagonal braces, the CSB allows the practical designer to choose the lateral stiffness independently from the yield strength of the device, due to its peculiar ad-hoc shape. In previous studies, analytical formulations and first experimental tests were described. In the present paper, the main results of further experimental tests conducted on scaled CSB specimens of full circular cross-section under both monotonic pseudo-static and cyclic loads are presented. The results of the experimental tests are compared with analytical formulations.

Abstract
The Crescent Shaped Brace (CSB) is a new steel dissipative device recently proposed by some of the authors within the context of Performance Based Seismic Design (PBSD). Contrarily to the conventional concentric stiff diagonal braces, the CSB allows the practical designer to choose the lateral stiffness independently from the yield strength of the device, due to its peculiar ad-hoc shape. In previous studies, analytical formulations and first experimental tests were described. In the present paper, the main results of further experimental tests conducted on scaled CSB specimens of full circular cross-section under both monotonic pseudo-static and cyclic loads are presented. The results of the experimental tests are compared with analytical formulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
