【摘要】 本文从理论上分析了FRP(纤维复合材料)加固混凝土结构的二次受力,对比分析了结构原配钢筋和后粘FRP各自的应力～应变关系。并且根据《规程》给出的考虑二次受力影响的计算公式,编程计算了各种因素对二次受力的影响,计算了钢筋混凝土梁工程实例,对理论分析和实例计算进行了比较。更多还原

【Abstract】 This paper set the concrete structure reinforced by the FRP (the Fiber Reinforcing Plastics) down for an object of study, and analyzes the concrete structure subjected to loads second time in terms of theory. Then took of the reinforcing bar in concrete and contrasted them with the stress-strain relation of the FRP stuck on concrete. According to the calculation formula, which consider of loads second time, in "The rules of operation", the influence of various factor to loads second time. As an example, this paper computed a reinforced concrete beam, and made a comparison between the theory analysis and example computing.更多还原
