Adobe construction in rural areas is quite common due to locally available material. In developingcountries, the adobe construction is increasing due to its thermal and acoustic properties. Different types of structureshave been built in ancient times from earth. From heritage point of view, the adobe construction is of great importancebut we cannot ignore its disadvantages due to its mechanical properties such as lower strength of masonry units, lack ofresistance to wind and rain. Adobe masonry has shown poor performance in past earthquake. The reason behind thatwas lower shear and tensile strength. Due to its massive weight of wall and excessive weight from roof, it attracts largeforces during ground shaking which it cannot resist and fail abruptly. People are unaware and they are regularlyconstructing these structures in their areas where seismic hazard is high. To improve the seismic capacity of these adobestructures different schemes had been developed, but in this research we have used Reinforced Concrete (RC)components as confining elements to improve its performance during earthquake. Two models have been tested on shaketable, one with vertical columns and beams and the other model with only beams at different level along the height ofwall. Comparison of Lateral strength of structure in term of base shear coefficient and stiffness has been made. Additionof vertical columns has increased structural stiffness and structural strength 3.50 times and 5 times respectively that ofmodel with beams only.
