【 摘 要 】

Architectural precast concrete cladding is a nonstructural system sensitive to both seismic floor accelerations and story drifts. Architectural precast concrete panels must be designed to resist forces in the out-of-plane direction of motion while accommodating in-plane story drifts. This requirement presents specific challenges to engineers, namely in terms of the design and detailing of connections intended to allow in-plane drifts 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 architectural precast concrete cladding and tieback connections were performed. This paper summarizes key results obtained from these experiments and applies these findings to developing guidelines for the drift-compatible design of tieback connections and corner systems.
