Tsunami-Resilient Building Assessment for Coastal Community of Karachi

The construction of resilient infrastructure and buildings is a key requirement for sustainable cities and communities. Tsunami is a natural hazard that can have a devastating impact on coastal communities. The 2010 Chile and 2011 Great East Japan tsunamis changed the way that structural engineers estimate design loads for structures. During these events, coastal protective structures and waterfront concrete buildings failed to sustain the tsunami hydrodynamic forces. This paper demonstrates the performance evaluation of a numerically simulated case-study tall building located at the Karachi coastal belt employing the ASCE 7-16 provisions. Results include the resilient-based assessment of the overall building and individual component performance when subjected to hydrodynamic loadings and debris damming effects due to active-sea debris such as wooden logs and shipping containers.
