Economic Factors in Roller Compacted Concrete Dam Construction
This paper deals with some of the economic factors that designers and contractors need to consider in the design and execution of an RCC dam. Costs for the RCC portion of the Upper Stillwater...

Principles of Holistic Medicine Applied to Infrastructure Maintenance: A Test Case
A humorous consideration of the question of whether holistic medicine�that is, the treatment of the entire physical and emotional configuration of the patient instead of the solely medical...

Tomorrow's Schools
While what's wrong with education looms as a national concern, many communities are doing something positive about it. They're constructing new schools designed...

Field Monitoring of a Modular Detached Breakwater System
A pair of modular concrete detached breakwaters was installed at a site on the New Jersey shore. This paper describes an eighteen month field monitoring program of the beach response to...

Reformulation Efforts for Panama City Harbor, Florida
Panama City Harbor is on St. Andrew Bay, an arm of the Gulf of Mexico, about 105 miles east of Pensacola and 230 miles northwest of Tampa. At the request of the non-Federal sponsor, the...

Santa Barbara Harbor Assessment of Shoaling Frequency
The City of Santa Barbara is addressing the recurring problem of shoaling of its harbor entrance channel. The City relies on income generated from harbor businesses that in turn require...

Naval Pier Foundation Design and Construction, Pearl Harbor, Hawaii
The paper presents a case study of foundation design and construction for a pier in Pearl Harbor. The study covers a review of site investigations, laboratory testing, pile selection and...

Study of Three Dimensional Crack Tip Location of Mortar by Acoustic Emission
Plain mortar specimens were tested under three-point bending. Experimental variables include the width of the specimen and the notch-to-depth ratio. The experimental results of 12 specimens...

Condition Monitoring of Structures Using Transient Response
Condition monitoring of structures by measuring transient response and tracking the derived modal parameters has been applied with success in three laboratory studies. Where modal parameters...

Pullout Testing of High-Strength Concrete Members
An experimental investigation of a high-strength concrete mixture was undertaken to measure and evaluate pullout and compressive strength properties. Two columns, a slab, and cylindrical...

On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...

Refined Analysis of Load Distribution Factors for Bridges
This paper presents a new approach for calculating the distribution factors for slab-on-girder bridges. This method considers the coupling of longitudinal and transverse effects. The governing...

Determination of In-Situ Stresses From Acoustic Emissions
Acoustic emissions (AE) are microseismic activities that are generated in concrete by cracking and damage. The rate of Acoustic Emissions, called the 'Event Rate', can provide indication...

Dugdale Model Applied to Crack Interactions
It is doubtful that modelling crack interactions problem within the context of elasticity adequately reflects the physical aspects as the failure of brittle material is approached. A model...

Probabilistic Assessment of Composite Structures
Formal procedures are described which are used to computationally simulate the probabilistic behavior of composite structures. The computational simulation starts with the uncertainties...

Retrospect and Prospect: Micromechanics
In the mechanics community the term micromechanics is often used to identify scientific efforts in which certain overall macroscopic material response and failure modes are characterized...

The Theory of Elasticity: 1950-1992 and Beyond: Concluding Remarks
Forty years ago the theory of elasticity could be completely characterized by A.E.H.Love in his monumental treatise as an effort to reduce to calculation the internal state of stress produced...

The Microstructure of Hardened Cement Paste and Concrete
Concrete is a composite material created from a mixture of a binder (hardened portland cement paste) and a filler (fine and coarse aggregates). Like any other composite material the physical...

Shear Resistance Models for Concrete Bridges
Statistical models are developed for the shear resistance of concrete bridge girders. Two structural types are considered: reinforced concrete T-beams and prestressed concrete AASHTO girders....

Recent Findings in Active Structural Control
Over the past decade, tremendous advancements have been made in the development of structural control paradigms and in the necessary supporting technologies. The fundamental paradigm that...
