Paper abstract bibtex There are major changes in the 2014 edition of CSA A23.3, which specifies the seismic design requirements for concrete buildings in the 2015 Canadian building code. Many changes relate to the design of shear wall buildings. Effective stiffness of a wall now depends on the ratio of elastic bending moment demand to flexural strength. Minimum height of plastic hinge regions depends on building height. Flexural yielding above the plastic hinge regions is deemed acceptable as curvature demands are expected to be small. Additional ductility requirements ensure flexural compression failure will not precede yielding of vertical reinforcement above the plastic hinge regions. A lower-bound shear correction factor is introduced to compensate for the short duration of the maximum higher mode shear force pulse, the lack of co-occurrence with maximum bending strains and the shear ductility of walls. The large shear force reversals that occur because of stiff diaphragms below the plastic hinge regions must be accounted for. There are new minimum anchorage requirements for horizontal steel in walls, revised requirements for the design of squat walls and for the design of moderately ductile coupled shear walls. A brief overview is given of the major changes to the design of gravity-load resisting frames for seismic displacements and the seismic design of building foundations, and; the entirely new provisions for the seismic design of concrete tilt-up buildings.
