摘要
本文依据材料力学和钢筋混凝土结构设计原理中的梁理论,分析了碳纤维布提高梁抗弯承载力的力学原理,指出在碳纤维布(CFRP)满足强度要求的前提下,碳纤维布与混凝土之间的剪切强度是控制梁提高抗弯承载能力的因素,提出了碳纤维布粘贴长度的计算方法。
According to the beam theory in materials mechanics and structural design principle of RC,the mechanical principle of enhancing flexural strength of beam with carbon fiber reinforced plastics sheet (CFRPs) is analyzed.Under the precondition of enough tension intensity for CFRPs,the flexural strength of beam is controlled by the shearing intensity on the interface of CFRPs and RC.The method calculating the length of bonded CFRPs is provided.
