High-rise buildings with unusual shapes and high-technological systems are commonly used by companies to represent their economic power. In many cases, equipment consisting of LED screen walls is frequently not compatible with wind-induced displacements and accelerations experienced at high floors. The aim of the research work is to design and optimize a control device for response reduction of a prismatic room equipped with LED screen walls on all sides. The control system is a passive sliding device located at the base of the room disconnecting the LED supporting frame from the building's floor. Fragility analysis is carried out to compute the probability of exceeding predetermined displacements and acceleration thresholds with and without the control system.

Abstract
High-rise buildings with unusual shapes and high-technological systems are commonly used by companies to represent their economic power. In many cases, equipment consisting of LED screen walls is frequently not compatible with wind-induced displacements and accelerations experienced at high floors. The aim of the research work is to design and optimize a control device for response reduction of a prismatic room equipped with LED screen walls on all sides. The control system is a passive sliding device located at the base of the room disconnecting the LED supporting frame from the building's floor. Fragility analysis is carried out to compute the probability of exceeding predetermined displacements and acceleration thresholds with and without the control system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
