Local architecture and construction techniques differ based on the traditional inheritance in each country and region. Unique construction techniques can be seen in Türkiye, China, Japan, Indonesia, Latin America, Africa, etc. This thesis concentrates on the safe structural design of the selected non-engineered confined masonry houses and contains development of applicable strengthening techniques to those non-engineered houses. The non-engineered houses evaluated in this thesis are in Indonesia, Southeast Asia, where it has a tectonically complex and seismically active area; this region consists of 3 large tectonic plates and 9 smaller plates. These plates with different movements have created subduction and fault zones that are continuously active. Unfortunately, most non-engineered confined masonry houses made from masonry are not appropriately built, and when earthquakes occur, severe damage or even total collapse happens at relatively low magnitude. Thus, this thesis concentrates on evaluation and strengthening techniques that can be applied to the typical traditional masonry house type while considering the out-of-plane bending capacity, crack generation via tensile stresses (such as opening wall at the corners), strengthening methods using additional columns-lintels and post-tensioning, and obtainability of the material which will be used to strengthen masonry houses.
