APPLICATION OF THE DAMAGE INDEX METHOD TO PHASE II OF THE ANALYTICAL SHM BENCHMARK PROBLEM

Abstract eng:
This paper presents research that utilizes the Damage Index Method to detect the location and severity of damage to the Second Phase of Analytical Studies of the Structural Health Monitoring Benchmark Problem developed by the ASCE Task Group on Structural Health Monitoring (TGoSHM). This method utilizes the ratio of curvature in the mode shape of the damaged structure vs. the undamaged structure. A shear-building model is utilized for damage detection of the unbraced frame system, both with full and partial sensor data. The location and severity of damage is carried out using the Damage Index Method for both existing damage patterns established by TGoSHM.
