The major output of this research project is the Seismic Retrofit Handbook. It is part of the overall research objective that simplified assessment tools to evaluate the available capacity in terms of displacement and strength of rc frame elements are compiled and if necessary, further developed, for the use by practicing engineers in New Zealand. In terms of focus of research work, the research team at the University of Canterbury has decided to concentrate on the following aspects:
- Reliable moment-curvature tools for sectional analysis of rc elements with inadequate details (poor bond etc).
- Damage limit state for beam-column joints in terms of maximum principal tensile stress and shear deformation.
- Evaluation of bond performance of plain round bars or inadequate anchorage length.
- Evaluation of lap splice failure in columns.
- Hierarchy of strength within a M-N interaction performance domain approach
- Assessment of beam-column joint shear capacity (using code approach & state-of-the-art approach).
