Abstract

AbstractThis keynote presents the findings from the UK Earthquake Engineering Field Investigation Team’s post-earthquake reconnaissance missions to the 2009 Mw7.6 Padang, 2011 Mw9.0 Tohoku and 2016 Mw7.8 Muisne earthquakes. The performance of buildings and geotechnical structures within the affected regions were investigated to gain insights on their design and construction deficiencies. Observations of damage to these structures are thereafter compared with the characteristics of the earthquake and nature of building codes in these countries. They include building damages attributed to a combination of structural resonance, deficiencies in reinforcement detailing, vulnerability to soft-storey collapse and soil liquefaction. The variations to soft-storey collapses between different earthquakes are discussed to shed light on construction practices in different countries.KeywordsResonanceReinforcement detailingSoft-storey collapseSoil liquefaction
