Abstract

Due to the current deterioration of some reinforced structures, it would be advantageous to discover a new method of reinforcement. The use of steel bars is currently the most widely used method of reinforcement in the civil engineering field. However, corrosion of the steel occurs, which in turn causes deterioration of the structure.

Shape memory alloy (SMA), also known as Nitinol, is the material being researched in this project to help alleviate deterioration. SMA’s performance is superior to that of the steel reinforcement. This material also holds many impressive qualities that would make it an exceptional type of reinforcement. It is believed that when the SMA is paired with a Fiber-Reinforced Polymer sheet, the performance of masonry walls would be enhanced under horizontal and earthquake loads. It is hoped that this material will be used more widely in the civil engineering field once more is discovered about its reinforcement characteristics.
