【摘要】 无黏结钢绞线体外预应力加固法已有部分被编入我国《混凝土结构加固设计规范》中。与传统的预应力加固法相比,无黏结预应力钢绞线加固法具有更多优势。比如屋面板的加固这个案例,就是利用无黏结钢绞线体外预应力加固法,通过施加体外预应力,使得原结构、构件的受力得到改善或调整。更多还原

【Abstract】 The exterior prestressed reinforcement technology of non bonded steel strand had been codified in permission for Design code for strengthening concrete structure in China.Compared with the traditional prestressed reinforcement technology,the reinforcement technology of the non bonded prestressed steel strand has more advantages.Take the concrete case technology about the roof panel for example,it use the external prestressed reinforcement technology of non bonding steel strand,adjusting the force of the original structure and the component by applying external prestressing force.更多还原
