Damage Detection Analysis of Reinforced Concrete Simple Beams Based on Three Dimensional Curvature Mode
The damage detection based on curvature mode was discussed in this paper, a three dimensional reinforced concrete simple beam model was established by finite element software, two models of before and after damage were compared also. The results showed that, before and after damage, the natural frequency, vibration modes and displacement modes had small difference, yet the curvature modes of model had great change in the location of damage.
