RISOutcrossing Rate Method for Nonstationary Non-Gaussian Performance Functions and Its Application to Time-Dependent Reliability Assessment
Publisher: American Society of Civil Engineers
Abstract: In recent decades, the outcrossing rate method has gained popularity for structural time-dependent reliability assessments (TRA). Despite numerous efforts, developing a general analytical outcrossing rate method for a ...
Sensitivity Analysis of Parameters Affecting Bearing Capacity of Silt Soil Bridge Pile Foundation
Publisher: ASCE
Abstract: To study the bearing capacity of a silt soil bridge pile foundation in a river estuary, the pile foundation of the Nangang River Bridge in Hainan Province was chosen as the research object of this paper. ABAQUS finite-element ...
Comparative Analysis of Temperature Field Model and Design of Cooling System Structure Parameters of Submersible Motor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The reliability of submersible motors is directly related to the operational life of offshore oil-gas resources exploration and development equipment, crude oil production, and drilling costs. Temperature field model and ...
Optimal Sensor Placement Strategy Considering Bayesian Identification Uncertainty and State Change in Bridge Health Monitoring
Publisher: American Society of Civil Engineers
Abstract: AbstractIn structural health monitoring (SHM) projects, sensor placement is critically linked
to the uncertainty of identification outcomes, directly determining the reliability
of monitoring results. Although existing ...
Explicit Model of Outcrossing Rate for Time-Variant Reliability
Publisher: ASCE
Abstract: The usual approach to time-variant reliability problems is PHI2 method, which defines the outcrossing rate as a two-component parallel system problem and calculates it through a two-dimensional numerical integration. To ...
