This seminar report explains the earthquake-resistant confined masonry construction and basic guidelines. Download in PDF, DOC, or PPT format. The main contents are the definition of confined masonry, how it is different from reinforced masonry, advantages, disadvantages, key factors influencing seismic resistance of structures, and types of failure.
Confined masonry construction has a great potential for saving lives and property in areas of high seismic risk. It is important to note that this type of construction is practiced in countries and regions of extremely high seismic risk. In most cases, the design of confined masonry buildings is regulated by the seismic codes of the countries where this construction has been practiced. In confined masonry, the construction mainly consists of masonry walls (concrete block units or made either of clay brick ) with horizontal and vertical RC confining members built on all four sides of a wall panel. Vertical members, called tie-columns or practical columns, resemble columns in RC frame construction except that they tend to be of the far smaller cross-section. Horizontal elements, called tie-beams, resemble beams in RC frame construction.
