Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...
Effect of Joint Rigidity on Buckling Strength of Single Layer Lattice Domes
The present paper discusses the effect of the joint rigidity on the buckling strength of single layer lattice domes, with regular three way grids, under vertical loading. The effect of...
Joint Probability of Superelevated Water Levels and Wave Heights at Duck, North Carolina
Storm events are typically classified as a percent occurrence or return interval based on their peak storm elevation. The stage is the combination of storm surge, astronomical tide and...
Joint Probability Distribution of Rainfall Intensity and Duration
Intensity-duration-frequency (IDF) curves are widely used for peak discharge estimation in designing hydraulic structures. Accurate interpolated and extrapolated intensity values are difficult...
Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...

Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
In Situ Treatment of VOCs by Recirculation Technologies
Confronted with contaminated land from the world wars and the postwar industrialization period, German researchers and practicing professionals have worked to develop processes for effective...
Hydraulic Model Studies of Recessed Curb Inlets and Bridge Drains
A large hydraulic model (64 ft long by 10.5 ft wide) was used to test several geometries of recessed curb inlets and three types of bridge drains. Testing was at 3/4 scale for the recessed...
Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
Laplace Valve Stroking for Complex Piping Systems
LaPlace valve stroking to control water hammer is applied in complex piping systems with friction and without friction. Two types of system are analyzed. The law of operation of the valves...
Partnering for Success
Partnering as a method of doing business is spreading throughout the construction industry. With everyone fed up with the litigious nature of the industry, partnering represents an opportunity...
Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD)
This publication, Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD), (ASCE 15-93), is applicable to buried concrete precast pipe intended...
Upgrading Dubai's Sewers
The sewerage system serving the city of Dubai in the United Arab Emirates, is plagued with odor and corrosion problems. System elements were deteriorating and failure rates were increasing....
America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...
Offshore Rescue
Restoration of wastewater ocean outfalls can be difficult, dangerous and environmentally challenging. Two recent projects, however, serve as examples of innovative outfall rehab. The first...

Rebuilding the Former Soviet States: Perspectives on the Construction Market
The ex-Soviet republics' potential cannot be ignored, but history has placed formidable obstacles in the way of transforming their construction industries. The author, who...
Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...
