200. SEISMIC DRIFT COMPATIBLE DESIGN OF ARCHITECTURAL PRECAST CONCRETE CLADDING: TIEBACK CONNECTIONS AND CORNER JOINTS

Architectural precast concrete (APC) cladding is a nonstructural system sensitive to both seismic floor accelerations and story drifts. APC panels must be designed to resist forces in the out-of-plane direction of motion, while they must accommodate in-plane story drifts. This requirement presents specific challenges to engineers, namely the design and detailing of connections intended to allow in-plane drifts (termed ?tiebacks?) and corners of the system. Presently, these important issues are addressed rather broadly in design codes, leaving the details to the discretion and experience of the designer. With the goal of providing practical guidance to designers, system and component tests on representative APC cladding and tieback connections were performed. This poster summarizes key results obtained from these experiments and applies these findings to develop guidelines for drift-compatible design of tieback connections and corner systems.
