Unreinforced masonry structures

Abstract

Unreinforced masonry is widely used in Australia as an architectural and structural material. Because of its high mass, lack of ductility and low tensile strength it is unsuitable for use in areas of high seismicity. However in countries of lower seismicity such as Australia it can be used provided it is designed, detailed and constructed correctly. This paper provides an overview of the use of unreinforced masonry in Australia and discusses the impact of the new seismic loading provisions on existing practice. It is shown that unreinforced masonry can still be used in most instances provided the correct design and detailing techniques are used and the requirements of the appropriate masonry standards implemented.
