Articles, Christchurch uncovered

As life-changing experiences go, the earthquake on 22 February 2011 was fairly significant. On the one hand, our house was red-zoned (but still liveable), friends lost their lives and the city lost many of the old buildings that, for me, … Continue reading →

Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of mid-rise or high-rise structures. This study mainly focuses on structural damage evaluation for a type of timber-steel hybrid structures, which incorporate prefabricated light wood frame shear walls into steel moment-resisting frames (SMRFs). The structural damage of such a hybrid structure was evaluated through shake table tests on a four-story large-scale timber-steel hybrid structure. Four ground motion records (i.e., Wenchuan earthquake, Canterbury earthquake, El-Centro earthquake, and Kobe earthquake) were chosen for the tests, with the consideration of three different probability levels (i.e., minor, moderate and major earthquakes) for each record. During the shake table tests, the hybrid structure performed quite well with visual damage only to wood shear walls. No visual damage in SMRF and the frame-to-wall connections was observed. The correlation of visual damage to seismic intensity, modal-based damage index and inter-story drift was discussed. The reported work provided a basis of knowledge for performance-based seismic design (PBSD) for such timber-based hybrid structures.

For This Way Up's last shows, presenter Simon Morton and longtime producer Richard Scott have trawled through the archives of 600 shows recorded over the past (nearly) 13 years. This week, they mark the major seismic events that occurred during their time on the airwaves; the Christchurch and Kaikoura earthquakes.

High rise developments dominate skylines and are contentious in many low rise urban environments. Christchurch is no exception and its residents have historically been vocal in articulating their opinions on matters they care about, especially in regard to projects they perceive will ruin their ‘garden city’. At the turn of the millennium, developers were preparing yet another proposal which would get the tongues wagging in Christchurch with the development of the former Ferrymead Tavern site on Ferry Road. The planning process was a long and antagonistic one with many individuals viewing the built towers with a look of ‘disgust’ and discontent. In an ironic twist, the seismic activity in Christchurch over the last few years which has had major implications for a range of planning issues, incrementally led to the death of highly controversial Ferrymead ‘Water’s Edge’ Apartments.
