Abstract:

On 24 August 2016, a Mw 6.8 earthquake occurred near Chauk, Central Myanmar. This earthquake caused a significant amount of damage over a very large number of historical monuments. After providing a general summary of the regional tectonic settings and seismicity, the observed ground motion is discussed, and the performance of structures in the epicentral area is addressed, focusing on the damage observed in both historical and recent constructions. The observed damage patterns and their extent are analyzed and interpreted in light of observed damage that was found. Lastly, seismic fragility curves of local buildings have been derived.

In the current research project, three work packages have been adopted. Firstly, ambient vibration measurements have been performed in a number of buildings in order to obtain the building’s dynamic properties. Secondly, Finite Element Models have been created in order to check the inelastic properties of selected buildings for different earthquake hazard levels. Finally, a long-term structural health monitoring system using low-cost sensors will be adopted in order to monitor and validate the response of critical infrastructure as well as inform local staff and building occupants of earthquake impact in real-time.
