Nonlinear Behavior of Ductile Iron Pipeline Joints
Experiments were performed on 4 in. (100 mm), 6 in. (150 mm), 8 in. (200 mm), and 10 in. (250 mm) pipelines with rubber gasket joints to determine their structural and stiffness characteristics...

State-of-the-Art Report on Steel Embedments
The basic philosophy underlying the design of steel embedments may be summarized as follows: (1) If an attachment can be located such that a group of cast-in-place anchors can be used...

Bending Mechanism for Rubber Gasketed Pipe Joints

Fracture Properties of a Pearlitic Nodular Iron

Retaining Walls: Competition or Anarchy?
Until the last 10 years, when a retaining wall was needed a cast-in-place concrete gravity or cantilever wall was used. Then along came Reinforced Earth, and this proprietary system began...

Evaluating External Pipeline Corrosion

Bellefonte Primary Containment Structure
Construction of the reactor building primary containment structure at the Bellefonte Nuclear Plant involved several specialized construction techniques. This two unit plant is one of the...

Design and Selection Considerations for Concrete Falsework
Modern cast-in-place concrete construction often requires the use of sophisticated falsework systems which carry significant and complex loadings. Since these falsework systems must satisfy...

Repair of Waterstop Failures
Various methods of repairing failed waterstops or creating new waterstops where the old ones have failed have been examined. The work considered primarily relates to high pressure conditions...

A Study of Downdrag on a Cast-in-Place Concrete Pile

Southeast Harbor Fill Project, Seattle, Washington

Concrete Microwave Tower is Award Winner
A microwave tower in Florida was built of cast-in-place concrete instead of steel, because: (1)Concrete was considered more esthetic than steel; and (2)concrete was more resistant than...

World's First Iron Bridge
In 1779, using a new man-made material, skilled English workmen built a single-span bridge of cast iron over a steep river gorge about 140 miles northwest of London. The result was a 424-ton...

Infilled Walls for Earthquake Strengthening
Five one-half scale reinforced concrete frames were constructed and tested under static reversed cycle loads to determine experimentally the effectiveness of infilled walls in strengthening...

Structural Performance of Cast-in-Place Pipe
Results of studies of the structural behavior of cast-in-place pipe under typical loads and field conditions are presented. Analyses include a simplified method along with studies based...

Modern Concrete Structures Survive Romanian Earthquake
On March 4, 1977, 35 buildings collapsed during a severe earthquake (7.2 on the Richter scale) in Bucharest, Romania. Thirty-two of the 35 were older structures, erected before World War...
