摘　　要：开展RC简支梁的黏钢-体外预应力综合加固试验,通过ANSYS有限元模型仿真分析,建立了黏钢-体外预应力加固梁抗弯承载力计算公式,并与试验和模型数据对比分析验证公式的适用性。The RC simply supported beams were studied in the comparative experiment which was under external prestressing combined with steel-plate gluing.Through the finite element model simulation analysis by ANSYS,the authors established the formula to calculate flexural capacity of strengthening beam by external prestressing combined with steel-plate gluing.Through the comparison with data of the experiment and the finite element model this article verified the applicability of the formula.
