报告简介 (Outline) :

Recent earthquakes in New Zealand have resulted in a significant change to structural design practice. The 2010/2011 Canterbury earthquakes highlighted the challenges in assessing and repairing modern ductile concrete buildings. In 2016, the Kaikoura earthquake highlighted the vulnerability of flexible multi-storey concrete frame buildings, with widespread damage to precast concrete floors. The difficulty in repairing damaged earthquake buildings and the expectations of building owner and occupants have resulted in a surge in seismic resilient construction implementing low-damage structural systems. Examples of recently implemented buildings will be presented, focusing on low-damage concrete buildings with post-tensioned rocking walls.

 

Despite being based on extensive research and development, there is still much to learnabout the design of such low-damage buildings. One aspect that requires additional attention is the interactions between structural components. Displacement compatibility between components needs to be considered during the design process and appropriate connection details implemented. Research into the performance of innovative wall-to-floor connections will be presented, including large-scale experimental tests and numerical modelling of tested buildings. This research has lead to the design of a 2-storey low-damage concrete wall building that will be tested at Tongji University as part of a joint ILEE-QuakeCoRE research project.
