Development of health monitoring system becomes an important task for structure damage identification.The variation of structural frequency before and after the damage is believed to be a most available and widely used modal parameter because of its easy testability and high measure precision.The second-order sensitivity of structural frequency to variation of stiffness is for the first time to be deduced.Based on second-order frequency sensitivity analysis,a damage parameter identification method is presented.The method used only frequency measurement before and after damage to locate the damage location and quantify the severity of the damage.For a shear building,most of the frequencies can be measured.Several frame models were made and studied using vibration test.Many cases,including single-damage and multi-damage with different severity and locations,were considered.Test results show that for shear buildings,damage severity and location can be calculated using frequency change method from structural frequency measurement.Also,the identification method based on second-order frequency sensitivity analysis is more accurate than that based on first-order frequency sensitivity analysis.
