粘贴钢板和粘贴碳纤维是加固混凝土结构常用的两种方法。为了更准确掌握和应用好上述两种方法,对其在加固混凝土结构时进行受力分析是有必要的。因此,本文以钢筋混凝土刚架拱桥的加固工程为例,应用有限元分析软件作为工具,分别计算了加固前结构设计截面的抗力与挠度,以及加固后结构关键部位的应力和挠度,分析其适用性,为确定合理的加固方案提供了保证,对其他桥梁结构的加固有一定的参考价值。
Paste the steel plate and paste carbon fiber reinforced concrete structure is commonly used in two ways. In order to more accurately grasp and apply the above two methods, it is necessary to analyze the force in strengthening concrete structures. Therefore, in this paper, reinforced concrete frame arch bridge reinforcement project as an example, the application of finite element analysis software as a tool, respectively, calculated before the reinforcement design section of the cross-section of the resistance and deflection, as well as the key components of reinforced structure stress and deflection analysis of its application It provides a guarantee for determining the reasonable reinforcement plan and has certain reference value for the reinforcement of other bridge structures.
