The Relative Strain as a Design Criterion for Buried uPVC Gravity Sewer Pipes
When designing buried plastic sewer pipes, the relative strain caused by deflection of the circular pipe section is of particular interest. The reason for increased interest is the present...
Strains Induced by Combined Loading in Buried Pressurized Fiberglass Pipe
In 1983 Owens Corning Fiberglas and Utah State University collaborated on a study of combined strain behavior of fiberglass pipe to quantify the bending strain reduction as a function...
Field Testing of 84-Inch-Diameter Plastic Pipe
During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m)...
Girth Weld Defect Tolerance Criteria
This paper describes the following criteria proposed for setting allowable defect sizes in girth welds: PD 6493:1980, 'Guidance on Some Methods for the Derivation of Acceptance...
Continuum Modeling of Discrete Structures with Geometric Nonlinearities
The modeling of geometrically non-linear discrete structures by an equivalent continuum is presented. The discrete-continuum analogy is developed by first isolating a unit cell of the...
A Study of Deformations in Concrete Faced Rockfill Dams
This paper presents the results of studies on the behavior of certain concrete faced rockfill dams (CFRD), which were conducted during the Basic Design of Machadinho dam in Brazil. The...
Small Strain Measurements Using Triaxial Apparatus
This paper presents a detailed testing methodology which can be used to determine the cyclic properties of soils at very small strains using triaxial apparatus. A discussion of specific...
Stress and Strain Responses of a Soil-Pipe System to Vehicular Traffic
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe presented the opportunity...
The Calculation of Ice Forces on Arctic Structures
Results of tests conducted to determine the relationship between uniaxial compressive strength of ice and crushing force are presented. A plot of normalized uniaxial compressive strength...
Easing Strains in Partner-Managed Firms
The family-like nature of partnerships promotes shared management responsibilities but creates conflict. Partnerships, like families, are often taken for granted by the partners. Nonpartners...
The Theory of One-Dimensional Consolidation of Saturated Clays
The theory of nonlinear finite strain consolidation is reviewed. A modification of the effective stress equation to account of settling and consolidation as a unified phenomenon is proposed....
The Use of Soil Mechanics Capabilities in a General Purpose Finite Element Program
This paper describes capabilities, points out features of implementation in a general purpose code, and describes some numerical considerations. The paper makes use of illustrative solutions....
