这篇主旨报告介绍了英国地震工程现场调查队对2009年巴东、2011年东北9.0和2016-7.8-Ne地震的震后勘察任务的发现。对受影响地区内的建筑物和岩土结构的性能进行了调查，以了解它们的设计和施工缺陷。然后，将对这些结构的破坏情况与这些国家的地震特征和建筑规范的性质进行比较。它们包括结构共振、钢筋细节缺陷、易受软层坍塌和土壤液化等多种因素共同作用造成的建筑物损坏。讨论了不同地震作用下软弱楼层倒塌的差异，以期对不同国家的施工实践有所启发。
This 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.
