Masonry in the seismic areas of the Americas, recent investigation and developments

Abstract

Masonry, the oldest construction method, has become one of the major competing systems in modern construction. The great interest in its use around the world is due to its metamorphosis from a brittle and fragile material to one that can successfully withstand earthquake and wind forces while maintaining those features that in the past made masonry the preferred construction material. This paper reviews in general terms, the use of reinforced masonry in the construction of bearing wall buildings. It describes the different ways used to reinforce masonry walls to withstand earthquake forces. It discusses current issues of interest and areas of research, related in particular to the seismic resistance capabilities of the system. The paper also reviews the current situation in countries located in seismic areas of the Americas, with particular emphasis in Latin American countries.
