  1. Week 4:Investigation and modeling of the Avondale Bridge in Christchurch, New Zealand Erickson Nguon University of Auckland, New Zealand July 24, 2013

  2. Project Overview • 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.

  3. Recent Progress • Adjust force-displacement values for each spring according to their yield strength • Defined hinges for the model • Ran an analysis of the model and ran into issues with moments far exceeding the hinge yield moments. Figure 1: Displacements results shown from the analysis

  4. Projected Progress • Address moment issues • Run analysis and check all potential issues: Geometry, Constraints/Restraints, Hinges & Moment Curvature, Soil Springs, and Displacement • Meet with Liam to review my recent progress of the model bridge

  5. Russell Birdman Festival Tony and I Kayaking to Russell to watch the festival Birdman Festival in Russell A man dressed up as a sting ray trying to jump 7meters to win $1000 NZD People dressed up as Elvis. They danced to Burning Love then jumped as far as they can into the water
