Abstract: Civil infrastructures are subjected to various loads over their lifetime, which leads to structural degradation. To understand and predict these dynamic behaviors of physical infrastructures, many mathematical structural ...

Abstract: Abnormalities of human walking are critical indicators for the early detection of the risk of trips and falls and of neuromusculoskeletal disorders such as joint impairments, Parkinson’s, and stroke. Understanding the ...

Abstract: This paper presents a structure- and sampling-adaptive approach for analyzing human footstep-induced structural floor vibrations to estimate footstep ground reaction forces (GRFs) and gait balance symmetry. Balance symmetry ...

Abstract: This paper presents a floor-vibration-based step-level occupant-detection approach that enables detection across different structures through model transfer. Detecting the occupants through detecting their footsteps ...

Abstract: This paper introduces three wavelet-based damage-sensitive features (DSFs) extracted from structural responses recorded during earthquakes to diagnose structural damage. Because earthquake excitations are nonstationary, ...
