ABSTRACT

As part of a combined effort at North Carolina A & T State University and The University of North Carolina at Charlotte, an investigation into the repair of unreinforced masonry structures is underway. The objective of this research is to develop a methodology for the design of fibre reinforced plastic (FRP) repair/strengthening systems for masonry shear walls. The prime focus of the investigation involves evaluating the use of small assembly tests to predict the behaviour of large scale structures. The small assembly tests were conducted on both brick and block masonry prisms and these prisms were subjected to either tension, compression, or shear loading to failure. The behaviour of the small tests were used to predict the performance of two large scale test specimens that were repaired/strengthened by FRP systems and the results were compared. Reasonable agreement was obtained during this comparison but further development is needed to improve the modeling procedures.
