摘要：
As one of the main structural types of houses in China, masonry structure is widely used in rural areas. At the same time, this type of building has severe earthquake damage records in history. The masonry houses are widely distributed in rural areas with the large quantity. Therefore, it is of great significance to adopt a reinforcement method with high efficiency, low cost, and easy construction method to improve the seismic performance of masonry buildings. As a commonly used industrial product, the polypropylene packing band (PP-Band) has the advantages of good tensile performance, strong durability and low cost. The joint action of a masonry wall and a PP-Band can combine their respective performance advantages, thereby improving the seismic performance of masonry structures. The quasi-static tests were carried out on two masonry walls reinforced with different strength of plastering mortar and two walls with and without PP-Band reinforcement. The failure characteristics of specimens, as well as the seismic performance indexes such as peak load, hysteretic curves, skeleton curves, energy dissipation capacity and stiffness degradation were compared and analyzed. The effect of PP-Band reinforcement on the seismic performance of masonry wall was systematically studied. The results show that the PP-Band can effectively improve the seismic performance of the masonry walls, and it has obvious effect on improving the load bearing, deformation and energy dissipation capacities of the masonry walls. © 2020, Editorial Office of Journal of Building Structures.
