What Light Through Yonder Window Breaks?

Broken stained glass in a window of the ChristChurch Cathedral. The photographer comments, "I only managed to get one picture of the badly earthquake damaged Christchurch Cathedral and I did not want to get the buttresses holding it up like some Medieval siege engine, so I thought this one was perfect. Looking through the window notice that the adjacent wall has gone and the blue windows belong to an office block across the road".

The Christchurch Cathedral after loosing its tower and spire after the 6.3 quake hit Christchurch 22 February 2011. The February 22 quake cracked pillars, twisted walls, shattered stained glass, collapsed buttresses, fractured masonry and toppled the tower. The rose window in the west wall collapsed in the June aftershocks. Demolition of the Chr...

The interior of the octagonal corner section of the Cranmer Court building, which housed Plato Creative from March 2008 to November 2009. The photograph showcases the building's intricate wooden ceiling and high windows. A stained glass crest is visible at the bottom of one of the windows reading, "Est. 1874. The spirit of this building lives on". Although designed to house a book depot, this section was used as the principal's office while Christchurch Normal School was operating from the building.

Experimental testing and modelling to address the performance of RC walls …

Research papers, The University of Auckland Library

The current seismic design practice for reinforced concrete (RC) walls has been drawn into question following the unsatisfactory performance of several RC wall buildings during the Canterbury earthquakes. An overview of current research being undertaken at the University of Auckland into the seismic behaviour of RC walls is presented. The main objectives of this research project are to understand the observed performance of RC walls in Christchurch, quantify the seismic loads on RC walls, and developed improved design procedures for RC walls that will assist in revisions to the New Zealand Concrete Structures Standard. A database summarising the performance of RC wall buildings in the Christchurch CBD was collated to identify damage modes and case-study buildings. A detailed investigation is underway to verify the seismic performance of lightly reinforced concrete walls and initial numerical modeling and small-scale tests are presented in addition to details of planned experimental tests of RC walls. Numerical modelling is being used to understand the potential influence that interactions between walls and other structural elements have on the seismic response of buildings and the loads generated on RC walls. The results from finite element analysis of a severely damaged RC wall in Christchurch highlighted the effect that the floor diaphragms have on the distribution of shear stains in the wall.
