As part of a large infrastructure project in New York City, many load bearing brick masonry structures are located adjacent to areas undergoing excavation, tunneling and blast. Due to the numerous structures involved, simplified methods to rapidly assess stability issues of the brick masonry load bearing walls and facades have been developed. Based upon these methods, repair techniques have also been developed and successfully implemented. The methods of analysis and sample results are presented with recommended areas of improvement. The relative sensitivities of the various parameters and assumptions required are also presented.
