Abstract

This guide provides information on the characteristics and design of connections between precast concrete components and between precast components and cast-in-place construction. The proper detailing and design of precast concrete connections are essential to the performance of a precast concrete structure. <br>This guide describes typical precast jointed systems and their connection types, performance, and characteristics, and provides recommendations for design and construction. Three classes of connections are identified and their characteristic and key design considerations given. Also included are guidelines for designing connections and their anchorage, a description of precast systems, typical lateralload- resisting systems, key design considerations, and erection requirements including special welding considerations.
