Research on Smart Concrete Structure Embedded with Piezoelectric Device

GUO Hao~(1,2),LI Ping~(1,2),WEN Yu-mei~(2*),CHEN Yu~21.College of Optoelectronic Engineering,Chongqing University,Chongqing 400030,China;2.The Key laboratory for Optoelectronic Technology & Systems,Ministry of Education,Chongqing 400030,China  
Under loading,the stress distribution in concrete specimen and PZT ceramic embedded are analyzed by the finite element method.A linear relationship between the loads and the stress produced on the embedded ceramic is found.According to the expressions of dissipation factors in terms of equivalent circuit parameters,the dissipation factors are obtained in stress experiments.It is shown that the dissipation factors perform some regularity with the loads.It demonstrates the validness of the method of structural health monitoring by embedded PZT ceramic.
