The time series analysis approach for damage detection employed by Los Alamos National Laboratory (LANL) is modified and applied to the benchmark building designed by ASCE task group for damage detection and localization. A two-tier prediction model, using the auto-regressive (AR) and the autoregressive model with exogenous inputs (ARX) is used for obtaining the damage sensitive feature. The da...

In this paper, A flexibility-based method for damage identification of cantilever-type structures is proposed. Using the linear relation between flexibility matrix element and structure parameter, the damage equation involving modal parameter and damage coefficient of each structure element is established firstly. Then, using the free vibration response signal of structure and the time-frequenc...

The Norgett-Robinson-Torrens displacements per atom function is commonly used to estimate the amount of atomic displacement produced by incident energetic particles. At low energy, this defined as a step presenting single threshold damage energy. But materials have different crystallographic orientation. Molecular dynamic simulations show that continuously varying energy probability best suited...

This study investigates the mechanical performance and a constitutive model of basalt-fiber-reinforced cemented soil (BFRCS) containing 0%, 0.1%, 0.3%, 0.5%, 0.7% basalt fibers with lengths 3, 6, 12, 20, 35 mm, respectively. Unconfined compressive strength tests were used to examine BFRCS varying fiber contents lengths. The test results demonstrate that content optimal quality is distribution u...
