Updating the New York City Water System
The New York City Bureau of Water Supply maintains extensive records of all water main breaks dating back at least as far as 1940. A computerized file of the main break records was prepared...
Advances in Underground Pipeline Engineering
The field of underground pipeline engineering has undergone a rapid growth during the last two decades. The analysis, design, construction, operation, and maintenance of underground pipelines...
Probabilistic Basis for Design Criteria in Reinforced Concrete
This collection of papers presents the results of research on the variability of reinforced concrete members carried out at the University of Alberta, Edmonton, Canada, during the period...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
Damage Mechanics and Continuum Modeling
Historically, the structural and mechanical engineers are conditioned to model a material in a purely phenomenological sense with little or no regard to underlying physical phenomenon...
Concrete Face Rockfill Dams?Design, Construction, and Performance
Concrete face rockfill dams are being used with greater frequency and to greater heights in the last decade. The developments leading to this progress are many and are addressed in the...
Predicting Sinkhole Collapse
Sinkholes erupt when a cavern or opening in the limestone rock below opens up to the surface. Florida's sinkholes have received most U.S. attention recently, but sinkhole geology is found...
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,...
Tunnel Shotcreting�Strength in Fibers
Steel fiber reinforced shotcrete (SFRS) costs less, has a lower rate of rebound and allows modern excavating equipment to advance with fewer interruptions than conventional shotcrete....
Watertightness and Seepage Control in Roller Compacted Concrete Dams
An unjointed mass of roller compacted concrete (RCC) can easily be proportioned and compacted so that it is essentially impermeable and 'watertight. ' Permeability tests of various field-placed...
Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
Simplified Design and Construction Control for Roller Compacted Concrete
This paper presents a simplified approach to the design and construction quality control of roller compacted concrete (RCC) based on research of previous projects, discussions with experienced...
Construction of Middle Fork Dam
Recently there has been increased interest in roller compacted concrete (RCC) for use in dams. However, to date there has been very little practical experience in construction. Middle...
Economic Considerations in Selection of a Roller Compacted Concrete Dam
Roller compacted concrete (RCC) has recently emerged as an economically attractive material for gravity dam construction, replacing the use of conventional concrete and even challenging...
USBR Design Considerations for Roller Compacted Concrete Dams
Current Bureau design criteria for concrete dams are based on analytical methods developed and improved over the years, evaluation of construction methods and post construction materials...
Engineering for Steel Construction
Establishing Patterns of Building Failures
Establishing statistical patterns of building failures can help engineers and architects prevent similar failures in the future and also reduce litigation. The Architecture and Engineering...
Innovative Engineering Completes Dredge Spoil Disposal Facility
A large dredge spoil facility was completed for the Fort McHenry Tunnel that received 3.5 million cu yds of dredged material, and was constructed so that it could be converted into a port...
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...
