© 2018 Springer Nature B.V. This study compares seismic losses considering initial construction costs and direct-repair costs for New Zealand steel moment-resisting frame buildings with friction connections and those with extended bolted-end-plate connections. A total of 12 buildings have been designed and analysed considering both connection types, two building heights (4-storey and 12-storey), and three locations around New Zealand (Auckland, Christchurch, and Wellington). It was found that buildings with friction connections required design to a higher design ductility, yet are generally stiffer due to larger beams being required to satisfy higher connection overstrength requirements. This resulted in the frames with friction connections experiencing lower interstorey drifts on most floors but similar peak total floor accelerations, and subsequently incurring lower drift-related seismic repair losses. Frames with friction connections tended to have lower expected net-present-costs within 50 years of the building being in service for shorter buildings and/or if located in regions of high seismicity. None of the frames with friction connections in Auckland showed any benefits due to the low seismicity of the region.

Steel frames are being used to shore the unstable facade of the St John the Baptist Church at Latimer Square while the building is being repaired and strengthened following the magnitude 7.1 earthquake that struck Christchurch on Saturday 4 September 2010.

The old Christchurch Railway Station Clock Tower was damaged during the 7.1 magnitude quake on 4 September 2010 and was braced by the wooden sleeve until repaired. However, although the sleeve did its job during the 6.3 magnitude quake on 22 February 2011, the lower part of the tower started to break away.

A protest is underway outside insurance company Vero's Christchurch's office, with building owners dismayed to be still fighting for earthquake repairs 10 years on.  The protest was organised by the owners of an 11 unit apartment block in New Brighton, who says Vero is purposefully delaying progress to wear them down.  RNZ's reporter Rachel Graham is at the protest and spoke to Meriana Johnsen

he 2016 Building (Earthquake Prone Building) Amendment Act aims to improve the system for managing earthquake-prone buildings. The proposed changes to the Act were precipitated by the Canterbury earthquakes, and the need to improve the seismic safety of New Zealand’s building stock. However, the Act has significant ramifications for territorial authorities, organisations and individuals in small New Zealand towns, since assessing and repairing heritage buildings poses a major cost to districts with low populations and poor rental returns on commercial buildings.

Relates to the three new categories for residential foundation design that have been developed and will be required for repairing and rebuilding homes in Canterbury following the earthquakes of 2010 and 2011. The 'zones' referred to in the cartoon are the colours designated to different degrees of damage to particular areas or buildings in Christchurch after the earthquakes.

Glazing systems are non-structural elements in a building that, more often than not, appear to be given little consideration in seismic design. Recent experimental work into glazing systems at the University of Canterbury, however, has shown that glazing systems can be very susceptible to serviceability damage, defined as loss of water-tightness. The focus of this paper is to highlight the difference in vulnerability of standard and seismic glazing systems and consider the implications of this for future repair costs and losses. The paper first describes the damage states chosen for glazing units according to the repair strategies required and expected repair costs. This includes three damage states: DS1: Water Leakage, DS2: Gasket Failure and DS3: Frame/Glass Failure. Implementing modern performance-based earthquake engineering, the paper proceeds to highlight a case study comparing costs and expected losses of a standard glazing unit and a seismic glazing unit installed on a case study building. It is shown that the use of seismic glazing units is generally beneficial over time, due to the early onset of serviceability damage in standard glazing units. Finally, the paper provides suggestions for designers aimed at reducing costs related to earthquake induced repairs of glazing.
