Project overview
Project Overview Christchurch, New Zealand

  • The objective of this project is to investigate and model bridges, specifically the Avondale Bridge in Christchurch. The bridge suffered severe structural damage following the 2011 Christchurch Earthquake.

  • To create computer generated models of the bridges in SAP2000 with loadings that reflect the Christchurch Earthquake and with this model we can validate it by comparing the data from the model and the actual earthquake.


Recent progress

  • Began modelling the south abutment and pile of the Avondale Bridge in SAP2000

  • Defined the nodes of the abutment and pile model, degrees of freedom, cross-sections of abutment and pile, and attached spring links resembling the soil

Dmytro, Marta, Tony, and I flew down to Christchurch to extract stone and mortar samples from various structures.

We extracted samples from a chapel, church/graveyard, St. Lukes, Arts Centre of Christchurch, and Fort Jervois.
