The paper first discusses some issues in regard to seismic performances and the last discussion lead to develop modified strengthening techniques of existing non-engineered brick-nogging buildings. Myanmar is extremely vulnerable to seismic activity. Also, most of local occupants construct their houses by using traditional building styles and methods. From the observation of past earthquake, such as Thabeikkyin earthquake, the existing brick-nogging buildings were reached the most vulnerable condition. Therefore, in this study, their seismic performances were targeted to evaluate. The arising question is how can define buildings adequacy and how they supply the sufficient structural performance. Non-linear static push-over method is the most widely preferred way of the assessment and performance evaluation issue. To evaluate their seismic performances, fragility assessments are used. Four damage stages (slight, moderate, extensive and complete) are used to classify damage conditions and the study of damage provides an important step in the evaluation of strengthening measures. In this study, strengthening methods were selected by considering various assessment issues such as their effectiveness, easy to use, cost-effectiveness and even include aesthetically.
