Abstract

The performance of cast-in-place reinforced concrete moment resisting frames incorporating precast prestressed concrete U-beam shells, subject to seismic loading, is investigated. The precast beams act  as permanent formwork and are not connected by steel to the cast-in-place concrete of the beam or column.  Three full scale beam-exterior colurnn subassemblies were tested to determine their seismic  performance characteristics when plastic hinge regions occur in the beams adjacent to the columns. Provisions for the seismic design of  such composite structures are discussed and additional design recommendations based on the test results are proposed where necessary. A numerical design example is included to illustrate the design approach.
