CFRC梁拉敏性试验研究

碳纤维混凝土（CFRC）是在普通混凝土中均匀加入一定形状、尺寸和掺量的短切碳纤维而构成的一种同时具有良好力学性能和机敏性能的本征型智能材料．由于碳纤维具有导电性能，把碳纤维加入混凝土中能改善混凝土的导电性。通过试验，研究了将碳纤维加入普通的钢筋混凝土梁后构件的拉敏性能，试验结果表明，CFRC构件的电阻变化与荷载、应变、挠度、裂缝发展具有相应的对应关系，并通过试验数据，回归出CFRC电阻变化与构件荷载之间的对应关系，为CFRC在结构健康监测中的应用提供了理论依据和量化关系。

Testing research of the dexterity character of pull in cfrc beam

Carbon fiber reinforced concrete is a kind of multifunctional concrete that uniformly admixing with the finite shapes, sizes and volume of stick carbon fibers. And it simultaneously possesses the character of dexterity performance and good mechanical performance. It can improve the electric performance of concrete by putting the carbon fibers into the concrete as a result of electric performance of carbon fiber. Researching the character of sensing ability in reinforced concrete test, change of resistance is related to stress, flexibility, crack and strain in CFRC girder. And analyze the corresponding connection of this four, regress the corresponding connection by data, founding definite theory basic and scale for the application of CFRC in health monitoring of structure.
