The effectiveness of using friction type mechanical connectors along vertical joints to improve the earthquake resistance of large panel precast systems is investigated. In particular, the paper examines the relative roles of these connectors and gap-friction action in the horizontal joints. Nonlinear time history dynamic analysis is employed to determine the design connector slip load at which response is optimized . The results show that reduced seismic response and enhanced structural integrity are achieved through use of such connectors. Design implications, as well as a tentative procedure for selecting these devices, are also discussed.
