Discussion of “Prediction of River Pipeline Scour Depth Using Multivariate Adaptive Regression Splines” by Amir Hamzeh Haghiabi
(American Society of Civil Engineers, 2019) -
Effects of Using EPS Geofoam as Compressible Inclusion on HDPE Pipe Behavior
(American Society of Civil Engineers, 2019)This paper presents the results obtained from an experimental study investigating the effects of using expanded polystyrene (EPS) as compressible inclusion on buried high-density polyethylene (HDPE) pipe behavior. A series ... -
Ratcheting Effect of Pressurized 90° Elbow Pipe under In-Plane Opening, Closing, and Reverse Bending
(American Society of Civil Engineers, 2019)The effect of opening-bending, closing-bending, and reversed-bending loads on the ratcheting behavior of pressurized Z2CND18.12N stainless steel 90° long-radius elbow pipe was studied using finite-element (FE) analysis. ... -
Increasing Performance of Water Distribution Network by Using Pressure Management and Database Integration
(American Society of Civil Engineers, 2019)The performance of a water distribution networks (WDN) varies according to various factors such as physical, operational, and environmental and should be monitored to reduce and control the water losses. This study discussed ... -
Effects of Loading Sequences on Remaining Life of Plain Dents in Buried Liquid Pipelines
(American Society of Civil Engineers, 2019)The integrity assessment of dents in liquid pipelines, as regulated by codes and standards, is based mostly on depth and threat integration, with strain analysis incorporated as a nonmandatory recommendation for gas ... -
Laboratory and Field Investigations on Geofoam
(American Society of Civil Engineers, 2019)Lightweight fill materials are being increasingly used as a construction material for enhanced construction operations featuring construction on soft ground, in cold regions, and in earthen structures and above buried ... -
Use of EPS Bedding Materials in Pipeline Installation
(American Society of Civil Engineers, 2019)Pipeline construction in open trenches requires an appropriate degree of compaction of the soil around and below the springline, and especially in the haunches area, to ensure embedment on the contact surface of the trench. ... -
Using TDA as an Engineered Stress-Reduction Fill over Preexisting Buried Pipes
(American Society of Civil Engineers, 2019)Routing utility conduits underneath buildings is not always an avoidable situation, especially in densely populated and congested urban centers. Placing the pipe at a shallow depth attracts substantial additional earth ... -
Direct Observation of Odometer Trajectory When Passing over Weld in Oil and Gas Pipeline
(American Society of Civil Engineers, 2019)An odometer is an important part of a pipeline inspection gauge (pig) for measuring distance and defining the position of pipeline defects. Due to the peculiarity of their construction, odometers are prone to unbounded ... -
Response of Gasketed Bell and Spigot Joint in Small-Diameter HDPE Pipes Subjected to Expected Field Demands
(American Society of Civil Engineers, 2019)Gasketed bell and spigot joints in flexible pipelines are expected to be subjected to shear force, diameter change (or ovalization), and rotation under field conditions. Nonetheless, only some of these demands and their ... -
Topology Design and Component Selection in an Urban Gas Network: Simultaneous Optimization Approach
(American Society of Civil Engineers, 2019)Natural gas is generally transmitted from production to consumption areas through an infrastructure of pipelines consisting of three separate networks, namely transmission, feeding, and distribution. The transmission network ... -
Erosion Void Condition Prediction Models for Buried Linear Assets
(American Society of Civil Engineers, 2019)Sewer pipelines are a major component of any infrastructure. In fact, they are subject to deterioration through their service lives. Although researchers are pointing out the consequences of erosion voids in sewer pipelines, ... -
Exploring the Design Space Governing the Lateral Buckle Capacity of Subsea Pipelines
(American Society of Civil Engineers, 2019)Three analytical methods are used to evaluate the lateral buckle capacity of perfectly straight pipelines supported by a seafloor foundation: the beam-on-elastic-foundation method, the Kerr thermal buckling method, and the ... -
Effect of Geofoam on Vertical Stress Distribution on Buried Structures Subjected to Static and Cyclic Footing Loads
(American Society of Civil Engineers, 2019)Buried structures, such as pipes and culverts, are extensively used for transportation applications. The existence of these structures within the soil mass causes a redistribution of stresses. The stiffness of the buried ... -
Fracture Mechanics Lifetime Prediction of Polyethylene Pipes
(American Society of Civil Engineers, 2019)Polyethylene pressure pipes are designed for service lives of at least 50 years. While so far lifetimes have been assessed by pipe pressure tests, due to improved slow crack growth (SCG) resistance and increased testing ... -
Compressibility and Shear Strength Properties of Tire-Derived Aggregate Mixed with Lightweight Aggregate
(American Society of Civil Engineers, 2019)Lightweight materials such as expanded shale/clay/slate or tufts and slag are used in the construction of rigid culverts to mitigate high earth loads and settlements. However, the cost of using lightweight aggregate can ... -
Pipeline–Soil Separation Model for Natural Gas Pipelines Subjected to Parabolic Driving Force
(American Society of Civil Engineers, 2019)In view of the nonuniform landslide driving force in practical cases and the common landslide–pipeline separation phenomenon, a new pipeline–soil separation model under the action of a parabolic landslide driving force is ... -
Adapting 360-Degree Cameras for Culvert Inspection: Case Study
(American Society of Civil Engineers, 2019)Prior video technologies such as closed-circuit television (CCTV) cameras have been used for culvert inspection. They are limited by the range of the area scanned and by the direction in which the camera is oriented because ... -
