System-wide seismic vulnerability of aging multiple-span multiple-girder bridges in low-to-moderate seismic hazard regions
Autor: Mandar M. Dewoolkar, Eric M Hernandez M.Eeri, John E Lens M.Eeri
Publikováno v: Earthquake Spectra. 37:1626-1651
This article describes the approach, methods, and findings of a quantitative analysis of the seismic vulnerability in low-to-moderate seismic hazard regions of the Central and Eastern United States for system-wide assessment of typical multiple span

Risk of Cascading Blackouts Given Correlated Component Outages
Autor: Eric M. Hernandez, Margaret J. Eppstein, Paul Hines, Laurence A. Clarfeld
Publikováno v: IEEE Transactions on Network Science and Engineering. 7:1133-1144
Cascading blackouts typically occur when nearly simultaneous outages occur in $k$ out of $N$ components in a power system, triggering subsequent failures that propagate through the network and cause significant load shedding. While large cascades are

Performance-based post-earthquake decision making for instrumented buildings
Autor: Milad Roohi, Eric M. Hernandez
Publikováno v: Journal of Civil Structural Health Monitoring. 10:775-792
This paper develops a decision making framework for post-earthquake assessment of instrumented buildings in a manner consistent with performance-based design criteria. This framework is achieved by simultaneously combining and advancing existing know

Non-negative constrained inverse eigenvalue problems – Application to damage identification
Autor: Chandler B. Smith, Eric M. Hernandez
Publikováno v: Mechanical Systems and Signal Processing. 129:629-644
Damage identification using eigenvalue shifts is ill-posed because the number of identifiable eigenvalues is typically far less than the number of potential damage locations. This paper shows that if damage is defined by sparse and non-negative vecto

Reconstructing Element-by-Element Dissipated Hysteretic Energy in Instrumented Buildings: Application to the Van Nuys Hotel Testbed
Autor: David V. Rosowsky, Eric M. Hernandez, Milad Roohi
The authors propose a seismic monitoring framework for instrumented buildings that employs dissipated energy as a feature for damage detection and localization. The proposed framework employs a nonlinear model-based state observer, which combines a n

Detection of spatially sparse damage using impulse response sensitivity and LASSO regularization
Autor: Chandler B. Smith, Eric M. Hernandez
Publikováno v: Inverse Problems in Science and Engineering. 27:1-16
This paper presents an impulse response sensitivity approach enhanced with a least absolute shrinkage and selection operator regularization in order to detect spatially sparse (localized) damage. The analytical expression for impulse response sensiti

Efficient sensor placement for state estimation in structural dynamics
Autor: Eric M. Hernandez
Publikováno v: Mechanical Systems and Signal Processing. 85:789-800
This paper derives a computationally efficient algorithm to determine optimal sequential sensor placement for state estimation in linear structural systems subjected to unmeasured excitations and noise contaminated measurements. The proposed algorith
