摘要
通过对3根混凝土简支梁的体外预应力加固试验,研究并分析了体外预应力混凝土简支梁加固后的二次受力特性,对于人们了解体外预应力加固后的工作性能及设计体外预应力钢筋时有一定帮助。
Based upon external prestressed strengthening experiment of three simple supported concrete beams the secondary mechanical charac- teristics of those beams after external prestressed strengthening are analyzed, which provide good references for the study of working performance of members after external prestressed strengthening and design of prestressed reinforcement.
