Intermittent Operation of Water Distribution Networks Considering Equanimity and Justice Principles
(American Society of Civil Engineers, 2015)Water shortages cause intermittent operation of distribution networks in many developing countries. Under limited economic resources and frequent water shortages, the expansion of water supply for municipal use is slow and ... -
Fluidic Drag Estimation in Horizontal Directional Drilling Based on Flow Equations
(American Society of Civil Engineers, 2015)Horizontal directional drilling (HDD) is a trenchless technology used to install underground utilities. The force required to pull a pipe through the borehole during installation is crucial to design engineers. Various ... -
Role of Grout Strength and Liners on the Performance of Slip-Lined Pipes
(American Society of Civil Engineers, 2015)As infrastructure built during the 20th century reaches the end of its service life, engineers and managers are increasingly turning to rehabilitation rather than replacement to potentially reduce costs. For corrugated ... -
Long-Term Maintenance of Culvert Networks
(American Society of Civil Engineers, 2015)Infrastructure systems in the United States are in need of urgent maintenance and rehabilitations. Preservation of culvert networks, a major component of U.S. infrastructure systems, at an acceptable level of serviceability ... -
Minimum Effective Length and Modified Criteria for Damage Evaluation of Continuous Buried Straight Steel Pipelines Subjected to Seismic Waves
(American Society of Civil Engineers, 2015)It is impractical in the dynamic analysis of pipelines to consider the whole length of the pipe in a numerical model. Therefore, a minimum length is desired for the pipe model so that its midpoint responses are not affected ... -
Industry Perceptions of Alternative Project Delivery Methods Applied to Trenchless Pipeline Projects
(American Society of Civil Engineers, 2016)The majority of trenchless pipeline projects delivered today use the traditional design-bid-build (DBB) system. Alternative project delivery methods (APDM) have been introduced to increase stakeholder integration and ... -
Experimental Study of the Effects Produced by a Backfilling Process on Full-Scale Buried Corrugated HDPE Pipes in Fine-Grained Soils
(American Society of Civil Engineers, 2016)High-density polyethylene (HDPE) pipes are widely used throughout the world due to their significant advantages. Most of the previous studies have focused on the behavior of the pipe-soil system under live loading and the ... -
Jointed Pipeline Response to Large Ground Deformation
(American Society of Civil Engineers, 2016)The performance of segmental pipelines under large ground deformation is strongly influenced by the axial pullout and compressive load capacity of their joints, as well as by the limits on joint rotation during permanent ... -
Study on the Seepage Field and Underground Erosion of a Loess Pipeline Foundation
(American Society of Civil Engineers, 2015)Because loess underground erosion is one of the major engineering geological problems in loess areas of China, foundation loess of the Zichang-Yongping section of West-East Gas Pipelines is taken as the research object. ... -
Buckling Strength of a Thin-Wall Stainless Steel Liner Used to Rehabilitate Water Supply Pipelines
(American Society of Civil Engineers, 2016)Stainless steel liners are being used with increasing frequency for the trenchless rehabilitation of damaged water supply pipelines in China. At present, there is little research on the buckling resistance of stainless ... -
Signature Failure Modes of Pipelines Constructed of Different Materials When Subjected to Earthquakes
(American Society of Civil Engineers, 2016)The 2010/2011 Canterbury (New Zealand) earthquakes caused significant damage to buried pipeline infrastructure. Observations of damaged pipes that were made during either repair or replacement were used to define representative ... -
Comparison of Statistical Models for Predicting Pipe Failures: Illustrative Example with the City of Calgary Water Main Failure
(American Society of Civil Engineers, 2015)Several statistical models have been proposed to study effects of different covariates in the failure of water pipes. In this paper, three statistical models, the Weibull proportional hazard model (WPHM), the Cox proportional ... -
Undrained Load-Displacement Behavior of Partially Embedded Pipeline on Seabed
(American Society of Civil Engineers, 2016)The initial embedment of as-laid offshore pipeline is one of the important design considerations for on-bottom stability analysis. Despite the significant advancement in the use of numerical and analytical methods to predict ... -
Vibration and Stress Analyses of Positive Displacement Pump Pipeline Systems in Oil Transportation Stations
(American Society of Civil Engineers, 2016)In oil transportation stations, the plunger motion exhibited by positive displacement pumps can cause a great deal of vibration that can influence the secure operations of the equipment and pipelines. If resonance between ... -
Neurofuzzy-Based GMDH-PSO to Predict Maximum Scour Depth at Equilibrium at Culvert Outlets
(American Society of Civil Engineers, 2016)In this study, the neurofuzzy-based group method of data handling (NF-GMDH) as an adaptive learning network was utilized to predict the maximum scour depth at equilibrium downstream of culvert outlet structures. The NF-GMDH ... -
Numerical and Experimental Study of Uplift Mobilization of Buried Pipelines in Sands
(American Society of Civil Engineers, 2015)Offshore oil and gas pipelines are commonly buried in seabed to provide environmental stability, thermal insulation and mechanical protection. These pipelines are frequently subjected to high thermal and pressure loadings ... -
Modulus of Soil Reaction Values Measured in Ohio Thermoplastic Pipe Deep Burial Project
