Corps of Engineers Experience with RCC Pavements
Roller compacted concrete pavements were first developed in the U. S. by the Corps of Engineers in 1975. Since that time, RCC pavements have been constructed throughout much of the U....
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...
Fly Ash Utilized in Concrete?Technology Update
Fly ash is frequently utilized as a pozzolanic substance in Portland cement concrete. Levels of such utilization, a reflection of current practice/technology, seem to have stabilized at...
Guidelines for Design and Construction of Pozzolanic Stabilized Base Course Mixtures
The American Coal Ash Association (ACAA) has developed a manual of recommended practice which contains guidelines for the design and construction of pozzolanic stabilized base course mixtures...
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....
Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...
Lateral Analysis of Drilled Piers Incorporating Soil Variability
In probabilistic studies, the mean or expected value of the parameter in question, along with its measured dispersion or standard deviation, are determined. In this study the Three Point...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
Prediction of Concrete Creep and Shrinkage by Sampling on the Basis of Correlated Random Material Parameters
There are many random parameters which influence creep and shrinkage of concrete. In all of the previous probabilistic studies the parameters are assumed to be mutually independent random...
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...
Actual Versus Assumed Behaviour of Girder Bridges
It is generally believed that the discrepancies between calculated and actual responses of bridges can diminish, to the point of being nonexistent, with refinement in the method of analysis....
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...
Reliability Analysis of Single-Headed Anchor Bolts
Several design equations for predicting the capacity of single-headed anchor bolts embedded in plain concrete have been recommended in the United States. The capacities predicted by these...
Dynamic Response of Tall Buildings to Wind Loads
The purpose of this study is to perform a probabilistic analysis of tall buildings subjected to wind excitation. A time domain simulation is first applied to the nonlinear problem. After...
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...
