Describes design and construction aspects of precast concrete moment resisting frames for the lateral load resistance of multistory buildings. Discussion will concentrate on the particular aspects of the framing system of a 13-story building constructed in Wellington, New Zealand. The building is octagonal in plan with a perimeter lateral load-resisting frame consisting of two-story high precast reinforced concrete elements. Each element includes a column plus two levels of beam stubs. In-situ concrete midspan beam splices and grouted steel sleeve column reinforcing bar splices form the joints between individual units. The paper also briefly presents other similar precast systems used for multistory buildings. A review of laboratory testing recently completed is given which confirms the good structural performance of the framing systems described.
