| 摘 要： | 在输入稳定通电功率条件下,利用热传导理论导出了碳纤维混凝土梁电热效应驱动下的内部稳定温度场及其位移理论公式,并导出了梁的上下表面温差及变形与输入功率的关系.通过碳纤维混凝土梁电热效应驱动下的变形实验,证明了理论模型的可信度,并由此确定了该混凝土的热导率和在该实验条件下的对流换热系数等有关物理参数,这将对机敏混凝土梁的变形自调节研究具有指导意义.

| Abstract: | The interior steady field of temperature and deformation of electrified CFRC beams are derived by using the theory about the conduction of heat. The relations of temperature gradient and the electric power are deduced and proved by the results of the experiments. Using the relations and the results of the experiments, the thermal conductivity and the convective heat transfer coefficient of concrete material are determined, which will be a guidance of deformation self adjustment for smart concrete beams. |
