In this paper, an efficient method for structural damage detection is developed based on model refinement theory. First, a submatrix approach using modal test data to stiffhess matrix correction is described. Then a damage assessment methed that has its basis in both dynamic and static measurements is derived from the submatrix approach.Loss of shiffness, both its location and extent, is identified by detemining the reduction factors corresponding to the submatrices being examined.

In this paper, an efficient method for structural damage detection is developed based on model refinement theory. First, a submatrix approach using modal test data to stiffhess matrix correction is described. Then a damage assessment methed that has its basis in both dynamic and static measurements is derived from the submatrix approach.Loss of shiffness, both its location and extent, is identified by detemining the reduction factors corresponding to the submatrices being examined. Order - reduced analytical model is utilized to match experimental model, the dimension of which is insufficient due to practical testing limitations. Finally, a computer simulated case is studied on a cantilever beam to illustrate the damage evaluating capability and to investigate the feasibility of the proposed technique for bridge structures' health monitoring.

Based on the analysis of the mechanism of damage to concrete dams, the concept, theory and methods are introduced for damage calculation, damage field calculation, and damage simulation, and damage simulation calculation is carried out for a concrete dam. In consideration of the difference between thermal damage and load-induced damage, a thermal damage model and its corresponding damage development equation are used in calculation. In addition, an equivalence coefficient of tension damage and compression damage of concrete under equal strains is introduced into calculation due to the equivalence of tension damage and compression damage.
