Repair and Maintenance of Masonry Structures: Case Histories.

The purpose of this study was to develop, review, and report case histories of repair and restoration to damaged brick and stone masonry structures for the purpose of presenting many acceptable repair and restoration techniques in use today. It is designed to familiarize the reader with some solutions to masonry restoration as well as provide further reference material for more detailed study. The study is organized to give a background of each structure, the general climatological data for the area in which the structure is built, a description of the problems the structure was experiencing or the reason for the rehabilitation, a review of the solutions and techniques used to accomplish the restoration, and the performance to date of the repairs that were made. In several cases, additional research information on repair techniques and repair goals have been provided to supplement the data on the repair. The case histories have been chosen to give a broad review of different types of deterioration to brick and stone masonry construction and the chosen solutions. The cases reviewed cosmetic restorative work as well as structural restoration and structural upgrading to earthquake resistance standards.
