摘要
为了探讨应用碳纤维片进行军用钢桥加固的有效性 ,利用弹塑性非线性有限元和弧长法对加固后的钢梁进行了全过程分析 ,并且初步说明了其加固原理。通过分析发现利用碳纤维片可以有效地提高军用桥梁的承载力、刚度与稳定性 。
To research the validity of strengthening the military bridge with Carbon Fibers, this paper analyses the strengthened steel-girder with the elas-plas non-linear finite element and arc-length method, and presents the principle of improving the stiffness and ultimate force of steel beam with Carbon Fibers. The analysis indicates that the stiffness, ultimate force and stability of military bridge with Carbon Fibers may be resumed and enhanced, and this method may be used to strengthen military bridge.
