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...
Getting to the Root of Sewer Problems
The ability to quantify and qualify work schedule in a clear, logical and precise manner can make the difference between an effective preventive maintenance program and one of 'trying'...
Internal Sealing of Large Diameter Pipelines
Underground piping has traditionally been repaired by making excavations at the joints and completing the repairs externally. However, with increasing labor costs, underground utility...
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,...
Water Pipeline Infrastructure; Design Now for Future Ease of Repair
This paper covers the general types of water pipe joints presently in the ground in the United States. It also covers the methods used to repair joints and damaged pipes, pipe cutting,...
Dynamic Analysis of the Joint Dominated Beam
A method is presented herein to determine the vibration modes of the Joint Dominated Beam. An example of a cantilever beam is selected for this purpose. The truss type beam is analysed...
Space Truss Construction Studies
The ACCESS Shuttle Flight Experiment, designed to evaluate EVA for on-orbit assembly of erectable truss structure, is reviewed and principal results are summarized. In addition, two on-going...
Pipe Jacking Advances
Pipe jacking is the remote placement of pipes underground by means of a tunneling machine that carries a train of pipe behind it. This is a relatively new technology in the United States,...
Development Activities: Albemarle-Pamlico Sound Area
Paper briefly describes historical and emerging development activities in the Albemarle-Pamlico Sound area selected for study by a joint State/U. S. Environmental Protection Agency Task...
Joint Review Panels ? A Cooperative Approach
The Joint Review Panel (JRP) developed out of a need to address the interests of various agencies on a local, state and federal level which have permit jurisdiction over offshore oil and...
Wastewater Technology Innovation for the Year 2000
The present state of wastewater technology research is on a decline because of shrinking funds. A national effort by professionals in all sectors of the wastewater establishment is encouraged...
Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
Changes in Management: International Great Lakes
Unprecedented changes in the binational management of the Great Lakes are underway. Problems and programs to solve them increasingly are being considered on an ecosystem (comprehensive,...
Avoiding Cracks in Brickwork
Many aspects of movement and differential movement have been discussed. However, other movements and effects of movement that have not been discussed may also affect the performance of...
Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...
Modern Methods for Automating Finite Element Mesh Generation
The collection of finite elements composing the finite element model is the finite element mesh. The five papers in this book describe computer aided methods for generating finite elements...
Research Needed for Civil Engineering in the Arctic
A survey is based on the work of the Research Committee of the ASCE Technical Council on Cold Region Engineering and findings in a number of previous reports on research needs in cold...
Recent Research on Composite Structures for Building and Bridge Applications
Continuing research has been carried out at Lehigh University on composite structural members, joints, and overall systems. This paper summarizes the results of research on four selected...
