A digitally manipulated image of Michael Parekowhai's sculpture 'On First Looking into Chapman's Homer' on Madras Street. The photographer comments, "This is the work of New Zealand artist Michael Parekowhai titled 'On First Looking into Chapman's Homer'. There are two bronze pianos and a very dominant looking bronze bull on each".

The increasing prevalence of mixed-material buildings that combine concrete walls and steel frames in New Zealand, coupled with a lack of specific design and detailing guidelines for concrete wall-steel beam connections, underscores the need for comprehensive research to ensure that these structures behave as intended during earthquakes. Bolted web plate connections, commonly found in steel framing systems, are typically used to connect steel beams to concrete walls. These connections are idealised as pinned during design. However, research on steel framing systems has shown that these connections can develop significant stiffness and moment resistance when subjected to large rotations during seismic loading, potentially leading to brittle failure when used in concrete wall to steel beam applications. This thesis was written to understand the seismic performance of concrete wall-steel beam bolted web plate connections, providing experimental evidence, numerical modelling insights, and design recommendations to address critical gaps in current design practices. The study is divided into three phases. First, a review of 50 concrete wall-steel frame buildings in Auckland and Christchurch was conducted to understand current design practices and typical connection details. The findings revealed significant variation in design and detailing practices and a lack of specific guidelines for concrete wall-steel beam connections. Second, an experimental programme was conducted on four full-scale concrete wall-steel beam sub-assemblages, each incorporating variations in connection detailing. The tests were designed to quantify the rotation capacity of concrete wall-steel beam connections, identify failure modes and investigate the effectiveness of potential connection improvements. Results demonstrated that concrete wall-steel beam bolted web plate connections designed using current design standards and following existing practices are vulnerable to non-ductile failure characterised by concrete breakout. However, using slotted holes in the web plate and bent reinforcing bar anchors instead of headed stud anchors improved connection rotation capacity. Third, a numerical model of a case study building was developed on OpenSeesPy, with different connection conditions assumed based on the experimental results. Pushover and time history analyses were conducted to evaluate the implications of different connection conditions (pinned vs non-pinned) on global building response and local member demands. The findings revealed that using non-pinned connection conditions does not significantly affect the global building response and shear and bending moment demands on lateral load-resisting elements. However, doing so generates overstrength moments on the connections that induce different actions on out-of-plane concrete walls connected to steel beams. Synthesising findings from all three phases, this thesis concludes with a proposed design procedure for concrete wall-steel beam connections based on a capacity design approach to ensure ductile failure modes and suppress brittle ones. Key recommendations include selecting appropriate bolt hole geometry and anchorage, providing sufficient rotation capacity, and accounting for connection overstrength in global analyses.

Shoppers and tourists in the Re:Start mall, seen from upstairs in one of the cafes. The photographer comments, "The new temporary city mall has been open in Christchurch now for a week. Buildings damaged in the earthquake have been demolished and replaced with cargo containers to create a new, temporary, Cashel Mall. I visited the mall yesterday and was quite impressed with what they have done. The cargo containers have been nicely converted, brightly painted and smartly branded to create some good looking stores".

An architect and art historian is setting up an action group to oppose the demolition of one of the most well-known churches in Christchurch, the Cathedral of the Blessed Sacrament. The church, registered as a Category 1 building with Heritage New Zealand, was damaged in the 2011 earthquakes and has sat in a state of disrepair ever since. Dr Anna Crighton is from Historic Places Aotearoa. She talks to Susie Ferguson.

Thousands of people have turned out for the National Memorial Service in Ōtautahi today, where the 185 victims who died in the Christchurch earthquake 10 years ago are being remembered. Maurice Gardiner's sister, Donna Manning, died in the CTV building collapse. Ms Manning was the presenter of CTV's Good Living Show, and her brother describes her as someone who was the life and soul of the party, and cared deeply for others.

A school pool, a BMX bike club and a music school are among twenty organisations in Christchurch that have benefitted from the final grants from an international appeal for re-building the quake-damaged city. The Christchurch Earthquake Appeal has so far raised almost 100 million dollars, and as our reporter Teresa Cowie discovered, the latest 8 million dollars that's been released from the fund is giving a welcome boost to residents.

Finishing touches are getting added to the country's biggest indoor sport and aquatics centre, which opens to the public in central Christchurch in less than a fortnight. The long-delayed $500 million building, Parakiore, has a 50-metre competition pool and five hydroslides, as well as nine sports courts and a High Performance Sport New Zealand training base. It replaces the much-missed QEII park facilities destroyed in the 2011 Christchurch earthquake. Anna Sargent reports.

The University of Canterbury's E-Learning team's temporary office in the James Hight building. The photographer comments, "First looks at our new temporary (maybe) office space. Our group will stay here until April or May 2011, then will move to another floor in the Central Library. House bar. This reception desk is not used now. A small kitchen is at the right".
