Managing disasters in New Zealand from a civil/structural engineering perspective

Abstract

Introduction: types of disasters Earthquake Earthquake in New Zealand - seismic assessment of existing buildings - effects of earthquake on existing buildings - damage pinched hysteretic behavior of mails - backbone curve of fastener through wood - hysteric behavior modelled by single link element - elements are implemented in walls - good match between numerical and experimental - energy dissipation comparison - the behavior of a wall wlth many links can be captured by a single link Christchurch, Feb, 2011 Christchurch: numerical comparison between actual and design level (previous) events, single storey wall Other applications: combined with passive energy friction dissipaters modelled numerically Earthquake – San Fernando Conclusions
