| 摘 要： | 从力学的观点,将被测对象混凝土构件和埋入其中的光纤光栅传感器看成是一种复合材料或复合体,首次将剪滞法理论(shear lag theory)应用于分析光栅传感器埋入混凝土构件时的应力传递规律,得到了光栅传感器的应力传递公式和应力传递系数.利用得到的光栅传感器的应力传递公式,计算了混凝土实验构件的应力变化情况,实验证明,理论计算结果和实测数据基本吻合.

| Abstract: | It is complex to analyze stress transferring rules of FBG sensor embedded in measured object, for example, concrete. The measured object, concrete, and the embedded FBG sensor are regarded as a composite. The shear lag theory is applied to analyze the stress transferring rule of FBG sensor embedded in measured object for the first time, and the stress transferring formula and the stress transferring coefficient of FBG sensor are obtained. The stress changing of the measured concrete component is calculated by using the stress transferring formula of FBG sensor. The experiment results are in general agreement with the theoretical analysis. |
