摘要
Abstract
Based on the failure characteristics of masonry structures under earthquakes, a strengthening strategy using external prestressing techniques was presented.The external prestressing technique proposed in this research was that the junctions and the main support regions of the walls were pre-pressured by stretching the tendons located on both sides of the walls.It is believed that the shear strength and the seismic performance of the masonry wall structures can be improved by applying this external prestressing technique.The effectiveness of this technique was investigated experimentally through shaking table tests of two 1∶ 4 scaled whole models, including an experimental model and a control one.The results show that this technique can not only increase the shear strength and the bending strength of the walls, but also improve the ductility and the energy dissipation capacity of the walls.Furthermore, the integrity and the overall stiffness of the structure are also enhanced without substantial increase of the structure weight.关键词
