中文摘要：
利用碳纤维水泥基（CFRC）材料的电热效应，通过对埋置于普通混凝土梁中的CFRC材料通电加热后产生的热膨胀可以实现对混凝土梁应变或挠度变形的主动调节和控制．实验验证了这个方案的可行性．根据弹性力学推导的理论值与混凝土梁挠度变形实测值非常吻合．通过改变内埋CFRC材料的输入功率和通电时间可以控制CFRC材料的升温速率和终点温度，继而控制混凝土梁的变形速率和最大变形值．
英文摘要：
Based on the Joule heating effect of carbon fiber-reinforced cement （CFRC） based materials, the strain or deflections of normal concrete beams can be actively adjusted and controlled by heating up the CFRC to thermal expansion, which is validated by an experimental study. The theoretical values of deformation of concrete beams calculated according to elastic mechanics agree well with the experimental data. By changing the input power and conduction time, the temperature increasing ratio and the terminal temperature of CFRC can be controlled. Therefore, the deformation ratio and the maximum deformation of concrete beam can also be controlled and adjusted.
