Volunteers photographed with one of Gap Filler's painted pianos. The piano has been set up at the demolished site of the Crowne Plaza Hotel. In the background, Gap Filler's Pallet Pavilion can be seen. The back of the piano has been covered by plastic sheeting with a picture of a dog. A wooden structure has also been built around the piano with Perspex and corrugated iron on top and plastic sheeting to the left and right. This is to protect the piano and pianist from wind and rain.

Pallet Golf', a Gap Golf course on a the site of a demolished building. It has been built by Gap Filler to look like a journey through Christchurch. A plastic road cone as well as mini road cones, road signs, tunnels and rivers can be seen. The course has been built using green felt, wooden pallets, tyres, planks of wood and bricks.

Assessment of the minimum vertical reinforcement limits for RC walls

Research papers, The University of Auckland Library

During the 2010/2011 Canterbury earthquakes, several reinforced concrete (RC) walls in multi-storey buildings formed a single crack in the plastic hinge region as opposed to distributed cracking. In several cases the crack width that was required to accommodate the inelastic displacement of the building resulted in fracture of the vertical reinforcing steel. This type of failure is characteristic of RC members with low reinforcement contents, where the area of reinforcing steel is insufficient to develop the tension force required to form secondary cracks in the surrounding concrete. The minimum vertical reinforcement in RC walls was increased in NZS 3101:2006 with the equation for the minimum vertical reinforcement in beams also adopted for walls, despite differences in reinforcement arrangement and loading. A series of moment-curvature analyses were conducted for an example RC wall based on the Gallery Apartments building in Christchurch. The analysis results indicated that even when the NZS 3101:2006 minimum vertical reinforcement limit was satisfied for a known concrete strength, the wall was still susceptible to sudden failure unless a significant axial load was applied. Additionally, current equations for minimum reinforcement based on a sectional analysis approach do not adequately address the issues related to crack control and distribution of inelastic deformations in ductile walls.
