Abstract:

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.

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).

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:

Variations in masonry construction techniques from country to country exists today. Basic terminology used to describe masonry construction is different throughout American countries. This technical publication provides an opportunity to correlate performance of various masonry construction methods so that more can be learned about the sensitivities, or commonalities, inherent in the construction techniques that are used. This timely publication is a set of technical papers on various related topics authored by engineers from various North, Central, and South American countries. This special publication will be of interest to designers, constructors and specifiers. Note: The individual papers are also available as .pdf downloads..

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.
