Myanmar is an
earthquake-prone country. Although earthquakes do not kill people, the
subsequent collapse of building, for example, can cause human death and
economic losses. In this study, hazard maps were initially used to implement an earthquake disaster mitigation strategy. Two cities, in particular,
Mandalay and Yangon, were selected to investigate the hazard risk of buildings
in the high and low seismic zones. A three-story reinforced concrete (RC)
building with brick walls was evaluated by the Japan Building Disaster
Prevention Association (JBDPA) standard and the Capacity Spectrum Method (CSM).
After evaluating the target building with the JBDPA standard and the CSM, it
was cleared that the target building did not meet requirements. Two simple
retrofitting methods, RC column jacketing and RC shear wall, were applied in
order to retrofit the target building. These two methods are not expensive and
they only require the application of a simple technology. After construction of
a small number of RC shear walls or increasing the size of selected columns on
the 1st story, the building could be designated safe, even in a very
high seismic zone. The results showed that we could obtain a satisfactory
earthquake-resistant building.
