Bond Strength of Roller Compacted Concrete
Roller compacted concrete, or RCC, is a dam construction method which consists of placing horizontal layers of no-slump concrete in 1- to 3-ft (0. 3- to 0. 9-m) lifts and compacting the...
Roller Compacted Concrete Mix Design for Pamo Dam
Pamo Dam is designed as a 265 foot (81M) high gravity dam that will be located on the Santa Isabel Creek in San Diego County, California. RCC volume will be approximately 491,000 cubic...
Evaluation of Cores From Two RCC Gravity Dams
Galesville Dam, Oregon, completed in August 1985, and Upper Stillwater Dam, Utah, completed in August 1987, are two RCC (roller compacted concrete) gravity dams featuring different approaches...
RCC Storage Pads at Tooele Army Depot, Utah
Two 30. 5 m (100 foot) by 91. 4 m (300 foot) ammunition storage pads, each 381 mm (15 inches) thick, were constructed by the Sacramento District of the U. S. Army Corps of Engineers in...
Rennick Yard RCC Pavement Design and Construction
Rennick Yard roller compacted concrete paving project consisting of 136,000 multiplied by (times) yd**2 (113,710 m**2) was completed in June 1986. The design load for this project was...
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Design of Roller Compacted Concrete Pavements
This paper reviews some of the differences between roller compacted concrete and conventionally constructed concrete pavements. These differences require additional consideration during...
Design of Ash Basin Dike across Cove
Embankments built over soft, unstable foundation materials had required that the materials either be removed or reinforced. With the introduction of geotextiles, it is now economically...
Low Permeability Liners Incorporating Fly Ash
This paper summarizes the results of a research study undertaken at West Virginia University to evaluate the feasibility of utilizing stabilized fly ash as a low permeability liner material....
Reliability Based Analysis of Contact Problems
The S.B. Batdorf model is modified to include the reduction in shear due to the effect of compressive stresses on the crack face. This new formulation was used to obtain the probability...
Probabilistic Model for Stability of Slopes
Presented herein is a probabilistic model based on derived distributions to predict shear strength of soils and the safety factor of slopes considering uncertain properties of soil, namely:...
Bridge Reliability Evaluation Using 3-D Analysis and Damage Scenarios
This paper reports analytical investigations into the system strength and reliability evaluation of existing bridges using 3-D inelastic analysis and damage scenarios. In this context,...
Damage Accumulation Models for Bridges
In the study summarized in this paper the serviceability and ultimate limit states were reviewed for concrete and steel girder bridges. A model is proposed to evaluate strength and remaining...
Reliability of Cracked, Prestressed Girders
For prestressed concrete structures in non-aggressive environments or where corrosion-protected prestressing strands are used, it may be possible to allow flexural cracking into the precompressed...
Applying the Time-Reliability Equation
This paper presents a methodology for rigorously including time-varying elements of reliability through the use of the time-reliability equation. An example reliability analysis which...
Quantifying Quality Improvement Programs
Structural codes are evolving to a limit state design basis in which the safety checks are derived from the underlying probability distributions of strength and loads. An example safety...
Fatigue Reliability of Ship Hull Girder
Based on estimates on uncertainties in wave loading and fatigue capacity the fatigue reliability of ship hull girder is calculated with respect to global vertical wave bending moment....
Diffusion Models of Crack Growth Due to Random Overloads
Stochastic diffusion models of crack growth are developed, reflecting uncertainty in applied loading and residual stresses near the crack tip. Applications are shown to (1) random vibration...
Dilatometers Settle In
The benefits of the dilatometer test DMT are described. This geotechnical in situ testing tool was developed and patented by an Italian professor and engineer named Silvano Marchetti....
Priority Integrated Pipe Evaluation
The selection of the most suitable pipe for a given site involves the consideration of many factors affecting pipe performance. The factors to consider in sewer pipe evaluation and selection...
