Paper Abstract

This study examines the potential use of wireless communication and embedded computing technologies within realtime structural control applications. Based on the implementation of the prototype WiSSCon system in a three story steel test structure with significant eccentricity, the centralized control architecture is implemented to mitigate the lateral and torsional response of the test structure using two MR dampers installed in the first story. During the test, a large earthquake time history is applied (El Centro earthquake) at the structure base using a shaking table. Three major performance attributes of the wireless control system were examined: (1) validation of the reliability of wireless communications for real-time structural control applications, (2) validation of a modified exponential damper model embedded in the wireless sensors to operate the MR dampers, and (3) exploration of control effectiveness when using WiSSCon in a centralized architectural configuration.
