RISHigh-Dimensional Reliability Analysis with Error-Guided Active-Learning Probabilistic Support Vector Machine: Application to Wind-Reliability Analysis of Transmission Towers
Publisher: ASCE
Abstract: Adaptive reliability analysis methods based on surrogate models, especially kriging, have been successfully implemented in many problems. However, the application of kriging is limited to low-dimensional problems with ...
Parametrized Wind–Surge–Wave Fragility Functions for Wood Utility Poles
Publisher: ASCE
Abstract: Wood poles are among key components of the overhead grid infrastructure that are highly vulnerable to wind hazards. In coastal regions where hurricanes are often accompanied with a storm surge, in addition to high wind ...
Fractional Order Filter Enhanced LQR for Seismic Protection of Civil Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents fractional order filters to enhance the performance of the conventional linear quadratic regulator (LQR) method for optimal robust control of a simple civil structure. The ...
Data-Driven Model for Estimating the Probability of Riverine Levee Breach Due to Overtopping
Publisher: ASCE
Abstract: Breach due to overtopping is the most common failure mode of earthen levees. Historic records and future projections consistently show exacerbating patterns in the frequency and severity of floods in several regions, which ...
Exploring Passive and Active Metamodeling-Based Reliability Analysis Methods for Soil Slopes: A New Approach to Active Training
Publisher: ASCE
Abstract: For geotechnical systems involving complex behaviors and significant uncertainties, metamodeling-based reliability methods based on fixed designs of experiment (passive metamodeling methods) are frequently applied. However, ...
