It has been identified that in New Zealand, unreinforced masonry (URM) buildings pose the greatest risk of structural collapse in an earthquake. Therefore a significant portion of this research project has been devoted to the assessment and retrofit or URM buildings. The different aspects of URM research are detailed below:

• New Zealand’s inventory of unreinforced masonry buildings

• Material properties of unreinforced masonry for use in seismic assessment and seismic retrofit design

• Studies on the seismic response of structural components in unreinforced masonry buildings

  • In-plane walls

  • Out-of-plane walls

  • Corners

  • Frame type structures

  • Diaphragms

• Desk-top seismic assessment of unreinforced masonry buildings

• Finite element time-history analysis of unreinforced masonry buildings

• FRP Retrofit Solutions

  • Studies on FRP retrofit

  • FRP best practice design guide

  • FEM modelling using FRP

  • FRP design examples

• Case studies on seismic assessment and retrofit of unreinforced masonry buildings
