Automatic Self-Supporting Timber Warehouse (ASSTW) is an innovative and sustainable structural system with a modal response strongly influenced by both the actual mechanical behaviour of structural elements and the load conditions. The structural analysis of ASSTW is typically carried out using numerical models calibrated referring to codified materials and connection properties. The reliability of the numerical simulations, used in the design phase, can be verified through modal identification on-site tests that also allow for a subsequent model update. This paper reports the main results of the modal identification on-site campaign, conducted by CIRI-EC laboratory of University of Bologna, of the new Rotho Blaas S.r.l. ASSTW in two different load conditions: unloaded warehouse with only the mass of the structural elements and partially loaded warehouse with eccentric mass. The subsequent model update phase is presented carrying out the most significant mechanical parameters to grasp the actual modal response of the structure.

Abstract
Automatic Self-Supporting Timber Warehouse (ASSTW) is an innovative and sustainable structural system with a modal response strongly influenced by both the actual mechanical behaviour of structural elements and the load conditions. The structural analysis of ASSTW is typically carried out using numerical models calibrated referring to codified materials and connection properties. The reliability of the numerical simulations, used in the design phase, can be verified through modal identification on-site tests that also allow for a subsequent model update. This paper reports the main results of the modal identification on-site campaign, conducted by CIRI-EC laboratory of University of Bologna, of the new Rotho Blaas S.r.l. ASSTW in two different load conditions: unloaded warehouse with only the mass of the structural elements and partially loaded warehouse with eccentric mass. The subsequent model update phase is presented carrying out the most significant mechanical parameters to grasp the actual modal response of the structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
