Rail Planning�Texas Style
The Dallas Area Rapid Transit (DART) Authority has a 25 year plan to build a 147 mile rail network�all without federal funds. When DART hits its 2010 target date for completing the rail...
Accounting for Every Pipe
The Norfolk Sanitary Sewer Inventory and Appraisal System contains individual records for each of the 20,000 pipe segments in the Norfolk sewer system. The data, assembled from construction...
Communication?A Common Vision
It is imperative that lines of communication remain open between those who represent the 'state of the art' in safety. The common goal of these interrelated disciplines...
Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
Pipe Laying Comes Out of the Trenches
Recent developments have shown that trenchless construction offers an effective and economically attractive alternative to conventional excavation. These findings are especially important...
Curved Sewers: Yes or No?
A study of curved sewer use in Southern California examines sewer design and maintenance of curved versus straight sewers. A telephone survey of personnel in design and maintenance of...
Repair�Don't Replace�Cracked Sewer Pipe
Approximately 0.5 mile (0.8 km) of 42 in. (1,07 m) diameter reinforced concrete was installed for a sanitary sewer project when the on site inspector discovered that numerous joints had...
The Sand Dam
Currently under construction is the 443 ft. high sand fill dam. Being erodible, pervious and liquefiable, sand would normally be considered as n unsuitable material to construct LaVueltosa...
Seismic Risk and Decision Analysis of Lifeline Systems
This paper provides general guidelines for performing lifeline seismic risk and decision analyses. Relevant input models are introduced as they support the performance of component and...
Performance of Water and Sewer Lifelines in the May 2, 1983 Coalinga, California Earthquake
Water supply and filtration systems for the City of Coalinga suffered little damage. The water transmission system suffered five breaks. The urban distribution system was disrupted, but...
Ocean Energy
The Ocean Thermal Energy Conversion (OTEC) component nominated this year as an ASCE Outstanding Civil Engineering Achievement involves the most critical design problem; the cold water...
Update on Impact Effects in Nuclear Plants Part I?Overview and Need for Integrated Approach
In this paper, an ASCE working group on impact effects in nuclear plants updates the review of this technology contained in a five-year-old ASCE report. In Part I, an overview is given...
Pipe Impact on Concrete Slabs
A series of pipe impact on concrete slab tests have been performed at the CEA's Cadarache Laboratory using the AQUITAINE II facility. The testing program was jointly sponsored...
Design for Whipping Pipe Impact on Reinforced Concrete Panels
This paper describes determination of local and overall effects on reinforced concrete panels due to whipping pipe impact in postulated pipe break events. Local damage includes the prediction...
Sensitivity of Peak Dynamic Responses to Input Factors
Responses have been calculated for the Zion Unit 1 plant, using the SSMRP computer code SMACS, as part of the seismic probabilistic risk assessment performed by the Seismic Safety Margins...
Piping Analysis: A Flexibility Approach
Design for the vertical and horizontal accelerations associated with a seismic event coupled with low allowable loads on equipment are two primary contributors to the current situation....
Update on Impact Effects in Nuclear Plants Part II?Review of Pipe Whip Impact
Current regulations require that pipe breaks be postulated in high-energy lines and measures be taken to prevent consequent damage to essential structures and systems. The paper addressed...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Design and Performance of Buried Fiberglass Pipes ? A New Perspective
The buried performance of fiberglass pipes was the subject of a comprehensive and multifaceted research program carried out in 1982 and 1983. Instrumentation, capable of accurately tracing...
