Notes:
A damage detection method reflecting initial damage of the elastic structure is presented.It is based on the idea that the damage will decrease the structure stiffness. From eigenvalue issue,regard Poison ratio and elastic modulus as a constant and a random variable, respectively, and interms of known data and a combination of the FEM, then equations solving random modulus of theundamaged and the damaged structure are obtained, respectively. Based on the element damageindicator, initial damage of the structure can be detected. At last, a five-storey shearing structure issimulated, and the results indicate that initial damage situation can be accurately calculated, andinitial damage locations can be estimated based on the proposed method, which is simple andeffective, and contributes to the application in Engineering
