Abstract:
Paper presents the state of the art of masonry design, construction, and supervision in Peru, a country subjected to severe seismicity. Masonry in Peru has always been the most important urban structural material, but one that had been used without any engineering control during design, construction, and supervision phases. The results were unsafe and/or wasteful. The information presented in this paper covers the following subjects: 1) design and construction practices, including materials, masonry walls, building configuration, codes and seismic design; 2) seismic behavior and retro fitting;and 3) research addressing materials, masonry specimens, and full-size walls and buildings. These concerns initiated an integral program 2 decades ago, with the main objective of rationalizing the structural and engineering treatment of masonry (until that time, merely a construction material).

A brief overview of the performance of masonry structures subjected to extreme lateral loading events, including earthquakes, hurricanes, tornadoes, and blasts is presented. The overview includes a phenomenological description of the resistance mechanisms of masonry structural systems, as well as common failure modes and their underlying causes. Observations made in 10 North, Central, and South American countries are summarized, along with pertinent discussion that compares and contrasts the various experiences. Coverage includes reinforced masonry, confined masonry, unreinforced masonry (load-bearing walls and infill panels), adobe and other nonengineered, handmade masonry.

An overview of different aspects of masonry research in the Americas is presented from the viewpoint of the response of masonry to extreme lateral forces such as earthquakes of strong winds. Research objectives, variables studied, and important findings are described. Due to the large number of investigations, the presentation is not intended to be exhaustive, and only the most relevant references are selected. With respect to the behavior of unreinforced and confined masonry, Latin American research is emphasized. With respect to the behavior of reinforced masonry, the U.S. TCCMAR program is emphasized. This chapter is organized into the following sections: material properties; unreinforced masonry; confined masonry; reinforced masonry; and masonry infills. To facilitate the transfer of research findings into design practice, design and construction details from several research projects conducted in different countries are described. Finally, needed research is discussed from an overall viewpoint.

Confined masonry walls constitute the basic vertical structural system for residential buildings up to five stories high in Mexico. The practice of their design and construction, their performance during recent earthquakes, and the changes in code regulations and in design and construction practice imposed by the lessons learned from the 1985 earthquake are discussed briefly. Also summarized is the experimental research that constitutes the basis for present design regulations. The comprehensive research program carried out since the late 1960s includes tests on units and mortars, small masonry subassemblages, full-scale walls, and complete structural systems.

Presents the general description of masonry systems and construction practices in the Americas. As the most important use of masonry is the construction of midheight buildings destined to housing, emphasis is given in this chapter on the use of masonry in the construction of bearing wall diaphragm buildings.
