Chapter presents a summary of the materials more widely used for masonry construction in different countries in the Americas. An attempt has been made to establish groups of similar masonry units, including typical values for some of the more important mechanical properties. Typical particularities for some countries are mentioned. However, only masonry units for structural purposes are discussed. Mechanical properties, mix characteristics, and particular details related to mortar and grout used in different countries are summarized. Grades and characteristics of reinforcement steel for masonry construction are presented. A brief summary of mechanical properties of masonry assemblages for different countries is included, together with a review of the appropriate local standards. Finally, some of the accessory materials for masonry construction are presented.
P. A. Hidalgo
The main characteristics of Chilean masonry construction are presented, including reinforced masonry and confined masonry. The seismic behavior of masonry is discussed, with special emphasis on the reasons for the poor performance of hollow clay brick reinforced masonry during the March 3, 1985 earthquake, compared with the rest of Chilean construction. The codes available for structural design are analyzed, including the development of the revised version of the seismic code to prevent damage in future earthquakes, and preparation of the draft for the design of confined masonry. Finally, the research done in Chile to develop the code provisions for the design of reinforced masonry structures is summarized.

Various types of masonry structural systems found in the United States are discussed, along with the range of masonry materials used in their construction. The system of masonry code development in the United States is reviewed and the principal masonry design codes and masonry material specifications are discussed. Finally, the current state of masonry research in the United States is summarized, with emphasis on the motivation for that research.
A description of masonry construction systems in Costa Rica is presented. Design and construction practice are briefly discussed, with emphasis on aspects of structural configuration and detailing of reinforcement. An example of medium-rise construction using reinforced masonry walls as the main structural system is given. An overview of Costa Rica's seismic activity, as well as a description of damage caused to masonry construction and typical repair and strengthening techniques, are presented.
Describes the design practice of masonry structures in the Americas. Emphasis of this study is on discussion of regulations for seismic resistance and design of masonry structures. Throughout the continent, unreinforced, reinforced, and confined masonry structures are used. Design practices evidence similarities in the methods used for the proportioning of reinforced and confined masonry in different countries. From the point of view of seismic design, different approaches are used, which lead to different strength and stiffness requirements.
