Buried Fiberglass Pipe Performance and Installation Requirements and Design Calculations in International Standardization
This paper elaborates on a proposed standard covering details of fiberglass pipe buried installation requirements and criteria for selection of pipe stiffness. It also discusses the selection...
Durability of Clay Pipe
Clay pipe, manufactured in accordance with ASTM C-700, has unusual resistance to attack by chemical agents. The pipe is highly stable in hydrochloric and sulfuric acid and subject to corrosive...
KEMCOR?A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...
Response of Buried Flexible Plastic Conduits Under Loading
Structural performance of 75 mm and 100 mm diameter plastic conduits embedded in Lloyd clay were examined experimentally in a laboratory soil bin, and numerically by the finite element...
Large Diameter Plastic Pipe Design
This paper presents a rationale for the design of large diameter plastic pipes for gravity flow applications. This procedure, applicable for all plastic pipes, adapts state-of-the-art...
Successful Use of Centrifugally Cast Glassfiber Reinforced Plastic (GRP) Pressure Pipes for Public Works in Sweden
Centrifugally cast GRP pipes were introduced in Sweden 17 years ago for industrial applications mainly as a gravity pipe. The process of pipe manufacturing as well as the pipe itself and...
Design of Non-Pressure Very Flexible Plastic Pipe
There is considerable debate about the correct structural design procedure to be used for very flexible plastic pipe (VFP) - typically glass-fiber reinforced pipe (GRP), reinforced plastic...
Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...
Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...
Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...
Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...
Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
Recent Developments in Hydrologic Instrumentation
The availability of space-age materials and implementation of state-of-the-art electronics is making possible the recent developments of hydrologic instrumentation. Material developments...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Ground-water Modeling on Small Computers: Past, Present, and Future
The paper reports on research that concerns the possible development of numerical models being able to simulate practical cases of Oil Spill Migration (OSPIM) in soils. Such models can...
An In-Plane Finite Element Model for Brick Masonry
A finite element model for brick masonry is reported. The model takes account of non linear deformations and progressive local failure. The failure may occur in the joints alone or in...
Behavior of Cavity Masonry Walls Under Out-of-Plane Lateral Loading: An Analytical Approach
In this paper, a finite element model is used to analyze cavity walls in an attempt to understand their complex behavior and to evaluate the adequacy of the assumptions embodied in the...
Shear Design of Masonry Walls
The paper presents a summary of a research project carried out at the Swiss Federal Institute of Technology Zurich to develop a design method based on the ultimate strength of masonry...
Wall/Floor-Slab Interaction in Brickwork Structures
The paper summarises the results of three series of tests on sections of brickwork structure carried out with a view to determining the characteristics of wall/floor slab joints in terms...
