Abstract
Experience from earthquakes has shown that the collapse of unreinforced masonry structures causes a larger number of loss of life during these events in developing countries. Therefore, there is an urgent need to improve their seismic performance to reduce future fatalities and to protect the existing housing stock. To effectively promote seismic retrofitting, inexpensive and simple technical solutions are required. Because in many regions self-construction is predominant, it is expected that any retrofitting initiative will also be taken by the house resident. Consequently, it is also important that the retrofitting procedure does not require highly skilled labor. Polypropylene band (PP-band) retrofitting method satisfies these two key requirements. PP-bands are commonly used for packing, which is inexpensive, worldwide available and durable. This paper focuses on reviewing the PP-band seismic retrofitting considering tests conducted to evaluate the efficiency of the retrofitting method, factors affecting the retrofitting, promotion technique, limitation and feature research focus of the PP-band retrofitting method.
