Confined masonry walls represent one of the most widely used construction systems for dwellings in Peru and other Latin countries. This study describes the procedure for implementing a database with a web interface of results collected from the experiments conducted over the years by the Japan Center for Earthquake Engineering and Disaster Mitigation. This paper attempts to contribute to the seismic design procedure of this type of structure, and parameters such as stiffness ratios and the deformation (drift) for the characteristic stages of confined masonry walls under different limit states or performance levels are proposed. Also, a semi-empirical equation for estimating the shear capacity using the database is proposed.
