Abstract:

A preliminary experimental study is presented which investigates the behavior of connections for architectural precast concrete cladding panels. The principal objective is to quantify the lateral stiffness capacity, energy dissipation properties, and ductility of representative precast claddings designs used on several highrise buildings. Hysteretic models will be developed on the basis of test and used to predict cladding influence on overall building seismic response in the linear and nonlinear stages of behavior. Test results are presented for three 3/4 in. diameter wedge-type inserts subjected to direct pullout.
