|Outline of Final Research Achievements
Urban area in developing countries has been getting highly dense due to economical growth and expansion. As a result of high density, upgrade of seismic vulnerability is one of most important issues to overcome earthquake disaster and keep resilience of urban cities.
Un-Reinforced Masonry (URM) walls are popular construction material in reinforced concrete buildings in main regions in the world. URM walls are generally non-engineered materials so that seismic capacity is not expected in structural design practice and severe damage has been observed in previous damaging earthquake disaster. In order to develop proper evaluation of URM walls, this research focuses on (1) Clarification of failure mechanism mechanism and influencing factors, (2) Development of seismic evaluation methods, and (3) Development of seismic retrofitting methods with local materials and construction practice.
