The recent apprehensions about active seismicity in Myanmar is a reminder of the significant hazards caused by earthquakes. Since some cities are subjected to high seismic risk, its assessment can be invaluable for disaster mitigation. This study focused on the development of fragility/damage probability functions for reinforced concrete (RC) buildings in Yangon city because seismic vulnerability assessment is being an essential component of risk evaluation. Nonlinear static pushover analysis is carried out on a group of 54 RC buildings (39 low-rises and 15 high-rises) by varying the material strengths, as well as and analysis based on capacity curves over the demand spectrum with fixed performance points representing the damage probability as a function of both spectral displacement and ground accelerations.
