碳纤维布加固梁刚度计算

Stiffness calculation of carbon cloth strength beams

指出在碳纤维布与加固梁有可靠的粘结、锚固的基础上,加固梁刚度会有较大幅度的提高,通过对混凝土、钢筋和碳纤维的本构关系和组合受力分析,给出了适用于工程设计的简化刚度公式。

It points out that on base of it has the firm bonding and anchor of carbon cloth and strength beams, the stiffness of strength beams may have big increase. Through analyzing the constitutive relation of concrete, steel bars and carbon fiber and the composite stress, it gives out the simple stiffness formula that adapted to the design of projects.
