Abstract
One of the very early types of masonry materials used in construction is natural stone. Sedimentary rocks such as limestone were used in building construction in Egypt during the 12th to the 15th century. Multi-wythe masonry walls made of two stone masonry outer wythes with a wide cavity filled with pieces of stone and low-quality mortar was the common type of wall construction in this period. Unsatisfactory seismic performance of these buildings has been observed in past earthquakes, especially during the most recent earthquake of October 12, 1992. A joint research program between Drexel University in Philadelphia and Helwan University in Cairo was initiated in 1997 to study the behavior of this type of masonry wall and to develop an effective retrofitting technique to improve the seismic resistance. This paper presents preliminary test results of wall elements retrofitted with grout injection and anchoring and tested under interface shear. It has been demonstrated that grout injection is effective in retrofitting multi-wythe historic masonry walls.
