SIMPLIFIED EVALUATION METHOD BASED ON WALL RATIO OF BRICK MASONRY BUILDINGS
This paper verifies the simplified evaluation method for the seismic performance base on wall ratio of masonry structure. Load bearing wall such as shear wall which are the main lateral earthquake resistant element in masonry buildings. Therefore, the wall ratio is one of parameters of seismic performance. Based on seismic calculation method for ultimate strength Route 1 in Japanese guideline, Simplified evaluation method based on wall ratio of brick masonry as Un-Reinforced Masonry and Confined Masonry in developing countries is proposed. In some countries, a preliminary computation usually used in the design phase is procedure known as wall density ratio which consists in finding the ratio between walls area and story area. The purpose of investigate is getting the potential of seismic performance of ordinary buildings based on the experimental data,and which can compare with minimum requirement. Cyclic loading test are conducted to investigate shear strength of masonry wall like Un-Reinforced Masonry and Confined Masonry in each countries (Present study is in Indonesia).
