【摘要】 我国现行的CFRP加固混凝土受弯梁技术规范以及研究的CFRP加固受弯梁方法,大多是建立在广泛的实验及工程经验的基础上,虽具有一定的适用性与合理性,却缺乏明确的力学概念,不易理解,结合混凝土力学的方法对钢筋混凝土梁加固后的受力进行详细的分析,得出受弯梁在各阶段的平衡方程、极限弯矩、抗弯刚度等,以及钢筋、混凝土、CFRP、的应力应变变化,并结合实例对所得到的理论计算承载力公式进行分析验证。更多还原

【Abstract】 The current technical specifications of CFRP reinforcing concrete beam and the analysis of the method of CFRP reinforcing concrete beam,are mostly based on extensive experiment and engineering experience.They have certain suitbility and rationality,but lack clear mechanical concept and could not be easily understood. Combining the method of concrete mechanics to analysis the stress of reinforced concrete beams detailly,and come to get the balance equation,ultimate bending moment,bending rigidity and the change of steel,concrete, CFRP’s stress of the bending beam in each stage.Combining the real example to analysis and check the theoretical capacity formula.更多还原
