摘要
采用连续多跨折线型设置的体外预应力高强钢绞线 ,通过两端纵向张拉和各跨中梁底横向张拉的方法加固受弯构件是工程加固处理中的新技术。
The members in bending can be strengthened by using prestressed high strength strands in continuous multi span folded pattern, tensile longitudinally at both ends and laterally at the beam bottom in the middle of span. It is a new technology for strengthening buildings. The typical engineering case presented in the paper explains the concept design and construction of this technology.[
