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.

Earthquake-resistant design of reinforced concrete structures has special problems in moderate seismic zones if the possibility of a very large rare earthquake exists. This is the situation in central and eastern North America. The questions and difficulties associated with introducing a seismic design code for the first time are discussed. The seismic risk to a populated region is not reduced much for many years after the code takes effect; only the rehabilitation of existing structures will reduce the risk significantly in a meaningful time frame. The overall behavior of buildings, especially of existing older reinforced concrete buildings, is often nearly elasto-plastic in nature because a mechanism forms soon after the formation of the first hinge and there is little or no overstrength. This may not be an optimum design in most cases. The response of reinforced concrete buildings to moderate ground motions designed only for gravity loads is better than expected, with moderate drifts and no premature brittle failures in most building types. That is not the case for the rare catastrophic earthquake.

Describes the essential features of the "modified compression field theory." A group of behavioral models based on these assumptions is presented. The use of these models is illustrated and reference is made to experimental data and to existing design codes. A simple, unified design method for shear that is able to approach both routine and unusual design problems is presented. The method is applicable to both prestressed and nonprestressed concrete members. It treats members subjected to either axial tension or axial

Summarizes the developments and changes to the seismic design provisions of the National Building Code of Canada (NBCC 1990) since its 1977 edition and discusses the changes to the seismic design provisions of the Canadian Standards Association Standard, Design of Concrete Structures for Buildings (CAN3-A23.3). The paper outlines the philosophy of seismic-resistant design of the Canadian code and discusses the changes to the zoning maps, static design procedures, and the introduction of the force modification factors. The paper also deals with the changes to the Canadian reinforced concrete code and especially with the section on ductile walls, changes to load combination factors, and the explicit links between the concrete code sections containing the detailing requirements and the NBCC sections on determination of the design seismic forces.
