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...
Simulated Field Trials of Non-Destructive Concrete Test Methods for Highway Structures
The data presented results from a two year Strategic Highway Research Program investigation into suitable NDT methods for determining the early age, and residual strengths of highway structures....
Review of NPP Concrete Degradation Factors and Assessment Methods
Degradation of concrete in nuclear power plant (NPP) structures can be an age-related phenomena. Several research programs have been initiated by the U.S. Nuclear Regulatory Commission...
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...
Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...
Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...

Grouting, Soil Improvement and Geosynthetics
The proceedings of the 1992 ASCE Specialty Conference on Grouting, Soil Improvement and Geosynthetics, addresses advances in the state-of-practice, research and technological developments...
Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...
Geomechanics of Subsidence Due to Pumping of Groundwater
In this talk we describe a nonlinear theory for the classical problem of pumping of groundwater from a layered soil. The model soil system consists of three horizontal layers where a very...
Probabilistic Mechanics in Civil Engineering
This paper describes the background, purpose and activities associated with the ASCE Engineering Mechanics Division and its technical committees. This includes research in probabilistic,...
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...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...
On the Diffusional Stress Transmission
A probabilistic diffusional mechanism for the propagation of intergranular forces has been formulated as a set of three mathematical assumptions. The equilibrium equations are complemented...
Particle Analysis of Material Behavior?A Note on Continuum Assumptions
Continuum models of materials have dominated our approach to the analysis of material behavior. Recently a number of discrete particle methods have been proposed which offer a different...
Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...
3D Frequency Domain Analysis of Offshore Structures
This paper reports the application of three-dimensional (3D) frequency domain computational tools to the dynamic analysis of offshore structure systems. Previous applications of 3D frequency...
