Abstract:

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.

Abstract:

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.

Abstract:

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.

Abstract:

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.

Abstract:

A review of the use of masonry in Columbia is presented. The importance of masonry construction is emphasized. The masonry structural systems prevalent in the country are discussed. A description of the materials employed in masonry construction in Columbia is given, including physical and mechanical properties. Reinforced masonry, confined masonry, unreinforced masonry, and nonstructural uses of masonry are discussed. Recent damaging Columbian earthquakes are presented. The behavior of masonry structures during these earthquakes, as well as their influence on the requirements of the Columbian Building Code, are given. The empirical design permitted by the code is indicated. Construction and inspection practice are briefly outlined. The procedures for evaluating and strengthening masonry structures are addressed. Past and current research on masonry is highlighted.
