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....
Dependence of Fatigue Damage on Loading Amplitude Variability
Welded steel specimens have been tested under variable amplitude loadings to determine the extent to which fatigue life is affected by the rate of amplitude variability of the loading...
Probabilistic Fatigue Crack Growth Analysis with Reliability Updating
A randomized fatigue crack growth model based on the Paris and Erdogan crack growth equation is used to estimate the reliability of fatigue sensitive details in steel bridges. This model...
Fracture Control for Arctic Vessels and Structures
Materials used for construction of Arctic structures and vessels are exposed to low ambient temperatures, high local ice loads and intermediate to high loading rates. All these factors...
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 Methods for Steel Members Subjected to Axial Load and Moment
There has been a significant amount of research performed on determining the reliability of elastic-plastic frames where failure is through the formation of a plastic collapse mechanism....
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...
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....
Resolving Reliability Issues for an Offshore Platform Code
A fixed steel offshore platform design specification based on reliability concepts has been developed which could become an alternate to the existing working stress code, American Petroleum...
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...
