Bridge Crossings with Ductile Iron Pipe

Ductile Iron Subaqueous Pipeline Crossings

Temporary Lateral Support System for Historic Building Facades in Boston
This paper describes a system of vertically cantilevered structural steel trusses, designed by the author, that provided temporary lateral support for a group of five and six story, 120...

Response of Ductile Iron Pipelines at Parkfield, CA to Loma Prieta Earthquake
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed at Owens' Pasture near Parkfield, CA. The site was...

Design of Ductile Iron Pipe on Supports
Design procedures for ductile iron pipe in normal underground service have been well established. The standard design considers hoop stresses in the pipe wall due to internal hydrostatic...

Corrosion Protection of Cast Iron and Ductile Iron Pipe, San Diego, California
This paper addresses the use of a loose unbonded plastic covering polyethylene encasement for protection of cast and ductile iron pipe in an extremely corrosive soil. The case study in...

Earth Retaining Structures - Developments Through 1970

Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...

An Expert System for Diagnosing and Repairing Cracks in Cast-in-Place Concrete Structures

The Use of Restrained Joint Ductile Iron Pipe
This paper addresses some of the problems we at U. S. Pipe have observed from restrained joint installations during the past several years and the solutions devised. The restrained joints...

Thrust Restraint of Buried Ductile Iron Pipe
It is the intent of this paper to present current state of the art thrust restraint design, present a basis for calculating required lengths of restraint, and to offer some practical suggestions...

Design of Ductile Iron Pipe Systems
To ensure a reliable, low maintenance infrastructure capable of withstanding the test of time, proper initial design is essential. The basis of the design standard for ductile iron pipe...

Sliplining with Ductile Iron Pipe
The utilization of Ductile Iron Pipe (DIP) as an alternative to be considered for sliplining rehabilitation of sewer pipelines is evaluated. A recent experience in sliplining a failing...

Effects of Ground Failure on Ductile Iron Pipe
The design studies and procedures outlined in this paper for pipelines that must cross earthquake fault zones are also applicable to similar ground disturbances resulting from landslides,...

Building Bridges the Old Way
Cast-in-place concrete bridges built on falsework, particularly post-tensioned box girders, are California's dominant structure type. Factors which have led to the popularity...

The Great Highway Coverup
Public opinion has forced changes in highway design since the first ones were built 30 years ago. In the Seattle area, this environmental sensitivity led to federal court action and to...

Tunnel Ceiling Replaced over traffic
The ceiling of the Holland Tunnel under the Hudson River, connecting New Jersey and Manhattan, was 59 years old and needed replacement, a big job because there are 3 miles of ceiling in...

A New Methodology for Modelling Water Pipe Breaks
A new methodology for modelling breaks in large diameter cast-iron water pipes is proposed. The need to consider two separate stages of deterioration (early stages with fewer breaks and...

Effect of Shallow Trench Construction on Cast Iron Pipelines
This paper summarizes the results of three-dimensional finite element analyses to evaluate the strains and displacements sustained by 4, 6, and 8-in. (100, 150, and 200 mm)-diameter cast...
