RISSensitivity Analysis of Tsunami Evacuation Risk with Respect to Epistemic Uncertainty
Publisher: ASCE
Abstract: To assess tsunami evacuation risk accurately in order to guide effective evacuation planning, various uncertainties (including the aleatory and epistemic uncertainties) associated with the evacuation process need to be ...
Appropriate Wrapping Width of Expansive Soil Embankment Built by Enveloping Method
Publisher: American Society of Civil Engineers
Abstract: In two sections of expansive soil trial embankments of Guangxi Ningming area, four monitoring profiles were set and series of testing elements were buried for field monitoring to find out the appropriate wrapping width. ...
Bayesian Updating of Bridge Condition Deterioration Models Using Complete and Incomplete Inspection Data
Publisher: ASCE
Abstract: Estimation of the time that a bridge or bridge component stays in a specific condition can guide decision-making on bridge maintenance and preservation. Statistical models of the time-in-condition rating (TICR) for bridges ...
Multifidelity Gaussian Process Model Integrating Low- and High-Fidelity Data Considering Censoring
Publisher: ASCE
Abstract: To investigate the behavior of engineering systems in the context of uncertainty propagation, sensitivity analysis, and design optimization, where large numbers of system model evaluations are needed, direct adoption of ...
Efficient Evaluation of Sobol’ Indices Utilizing Samples from an Auxiliary Probability Density Function
Publisher: American Society of Civil Engineers
Abstract: A sample-based evaluation of Sobol’ sensitivity indices is discussed in this paper relying on Kernel Density Estimation (KDE) for achieving computational efficiency. The foundation of the approach is the definition of an ...
Borehole Stability Analysis in Fractured Porous Media Associated with Elastoplastic Damage Response
Publisher: American Society of Civil Engineers
Abstract: A dual-porosity finite-element model is presented for stability analysis of boreholes drilled in fractured porous media with the consideration of elastoplastic damage response. Governing differential equations adopted in ...
Strain Localization in Unsaturated Elastic-Plastic Materials Subjected to Plane Strain Compression
Publisher: American Society of Civil Engineers
Abstract: Analytical solutions have been derived for the onset of strain localization in a broad class of unsaturated elastic-plastic porous materials based on Bishop’s definition of effective stress. Critical hardening moduli for ...
Self-Excited Second-Order Azimuthal Thermoacoustic Instabilities in an Annular Combustor With Oblique-Injecting Swirling Burners
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we experimentally investigate the thermoacoustic instability issue in an annular combustor with 16 oblique-injecting premixed swirling burners. It is demonstrated that there exist three dominant modes in a ...
Extracting Design Rationale in Technical Literature to Provide Inspirational Design Stimuli
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Design rationale (DR) explains why the solution is designed the way it is, and can be used to stimulate creativity and facilitate the development of new solutions in the conceptual design phase. DR was mainly captured by ...
Stochastic Modeling of Deterioration and Time-Variant Performance of Reinforced Concrete Structures under Joint Effects of Earthquakes, Corrosion, and ASR
Publisher: ASCE
Abstract: To assess the time-variant performance of RC structures, it is important to model the various deterioration processes as well as their interactions in addition to the associated uncertainties. Besides earthquakes and ...
