摘　　要：砌体结构体外预应力加固技术具有较好的经济性,是一种十分有效的抗震加固技术,具有广泛的适用范围。根据课题组前期已完成的专项振动台缩尺对比试验成果,在大量阅读相关研究文献的基础上,本文报道了砌体结构体外预应力加固技术的设计计算方法、预应力损失取值、以及预应力筋的锚固、张拉、防护等施工方法,作为该课题的后续研究成果,以便工程技术人员及科研人员参考借鉴。External prestressing is a comparatively economical and very eilectlve strengthening technique for unreinforced masonry structures, and it has extensive application. According to the experimental results of the shaking table model tests completed by our research group before, and based on a large number of studies conducted in the past by various researchers, this paper reports the design and calculation method, the possible prestressing losses considered, and the construction method for mason- ry structures using external prestressing technique for improving seismic performance. As the follow-up research work of this subject, this paper can be used as a reference for engineers in the future similar ex- perimental studies.
