ABSTRACT

Deformability is one of the key factors to describe seismic performance of structures from an earthquake engineering point of view. Deformation capacity must be given for their performance-based seismic designing or diagnosis. This chapter shows actual deformability of the brick masonry walls evaluated from the full-scale house models in shaking table tests. Deformability must be considered in the performance-based designing methodology developed for reinforced concrete structure, timber structures and steel structures. In developing countries in seismic regions, non-engineered masonry houses are constructed mainly because of economic reason. Deformation capacity was evaluated for the out-of-plane behaviour, as the model structure collapsed by the out-of-plane response. Deformation capacity of brick walls was evaluated from a series of shaking table tests of full-scale model houses. Deformation capacity in dynamic phase was estimated to be 1/60-1/70 for both in-plane and out-of-plane performance.
