Abstract

The Japanese and Peruvian experimental databases on confined brick masonry walls are put together as one database, and the strength and deformation of the walls are reviewed. First, the applicability of existing equations for the ultimate strength of reinforced concrete or reinforced masonry walls to the estimation of the maximum strength of confined brick masonry walls which failed in shear, flexural-shear, or flexure when subjected to lateral forces, is discussed. Then, empirical equations for the maximum strength, displacement at maximum strength, and ultimate state of the walls are proposed based on multiple regression analysis, and the accuracy of the proposed equations is discussed. It is concluded that the maximum strength can be estimated using the existing equations or the proposed empirical equations with good accuracy. The deformations at maximum strength and the ultimate state can be estimated using the proposed empirical equations, although there is a large amount of scatter.
