| Abstract: |
Outrigger systems are commonly used in the design of tall buildings to increase their lateral stiffness and resistance capacity. Recently, new applications for outrigger systems have appeared, such as providing additional damping or acting as fuses under earthquake conditions. While their main purpose varies from one project to another, the problem related to differential displacements between the core and the peripheral columns remains a constant. This paper aims at exploring various technical aspects considered in the design of the Silver Tower (Brussels) and, more specifically, the design of its outrigger system. It will show how the proposed system presents an effective and elegant solution to free the outrigger system of the lock-in forces due to differential settlements. Also, aspects related to the foundation system, the performed wind tunnel tests and the dynamic response of the tower will be discussed. |
