RISFailure Mechanism and Bearing Capacity of Footings Buried at Various Depths in Spatially Random Soil
Publisher: American Society of Civil Engineers
Abstract: The objective of this paper is to demonstrate how the spatial variability of random soil affects the failure mechanism and the ultimate bearing capacity of foundations buried at various depths. A nonlinear finite-element ...
A Prediction Model of Casing Wear in Extended-Reach Drilling With Buckled Drillstring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Buckled drillstring easily existed in extended-reach drilling (ERD) engineering, causing casing wear more severe. However, the effect of the buckled drillstring on casing wear prediction is going unheeded in long-term ...
Using Bayesian Statistics to Estimate Chlorine Wall Decay Coefficients for Water Supply System
Publisher: American Society of Civil Engineers
Abstract: A model of pipe wall and hydraulic profile effects on free chlorine decay in a water distribution system is developed using a two-step parameter assignment method. The model employs a Bayesian statistical method and Monte ...
Data Mining to Identify Contaminant Event Locations in Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: To respond to growing concerns related to potential contamination ingress via backflow and/or terrorist threats to drinking water, a data mining approach is developed. Use of this data mining approach, in conjunction with ...
A Novel Classification Method to Random Samples for Efficient Reliability Sensitivity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reliability sensitivity analysis is important to measure how uncertainties influence the reliability of mechanical systems. This study aims to propose an efficient computational method for reliability sensitivity analysis ...
Evaluation Method of Track Vertical Irregularity on Bridges Based on Vehicle Running Status
Publisher: American Society of Civil Engineers
Abstract: Evaluating track irregularities is crucial for ensuring the safe operation of trains since they serve as the primary source of excitation for vehicle systems and track structures. In China’s high-speed railway networks, ...
Analysis and Validation of a Unified Slip Factor Model for Impellers at Design and Off-Design Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a unified slip model for axial, radial, and mixed-flow impellers. The core assumption of the model is that the flow deviation or the slip velocity at the impeller exit ...
Influence of the Cement Fineness on Strengths of Cement Pastes Containing High Phosphorus Slag
Publisher: American Society of Civil Engineers
Abstract: Mechanical grinding was used to increase the specific surface area of cement in order to increase the dosage of phosphorus slag (PS) in Type
Topology Optimization of Total Femur Structure: Application of Parameterized Level Set Method Under Geometric Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Optimization of the femur prosthesis is a key issue in femur replacement surgeries that provide a viable option for limb salvage rather than amputation. To overcome the drawback of the conventional techniques that do not ...
Static Behavior of Circumferential Stress-Releasing Anchor for Large-Capacity FRP Cable
Publisher: ASCE
Abstract: In this study, an optimized anchor system to enhance the anchor performance of multiple-tendon fiber-reinforced polymer (FRP) cables was proposed and evaluated. The manufacture of the cables comprised 37 basalt FRP (BFRP) ...
