FRP混凝土结构力学性能的实验研究

An Experimental Study on the Mechanical Properties of FRP-Concrete Structure

本文首次引入基于马赫-曾德(Mech-Zehnder)原理的全光纤应变传感器系统到FRP混凝土结构的力学性能研究中,通过四点弯曲试验来测量试件内部的应力应变状态,并结合电测结果进行综合分析,为进一步的理论分析和计算奠定了实验基础.

The fiber optic strain sensor system based on the MechZehnder interferometer is introduced into the study on mechanical properties of FRPconcrete structure, for measuring the internal stressstrain state of the specimen in the fourpoint bending test. The results of fiber optic sensor combined with the results of electrical measurement are comprehensively analyzed, and used to establish the base for the further theoretical analysis.
