A Phenomenological Approach to Physico Chemical Phenomena Coupled with Damage in Massive Concrete
This paper presents the first experiments which have been done to support the bases of a thermomechanical model coupled with damage and to identify the characteristics parameters needed...
A Model to Predict Restrained Shrinkage Cracking of Fiber Reinforced Concrete
Cracking due to restrained shrinkage occurs very often in an engineering practice, causing serious problems such as increased water permeability of the structure and corrosion of the reinforcement....
Influence of Finite Deformations in the Stress-Strain Modelling of Granular Media
An incremental formulations of the stress-strain law is presented for quasi-static deformation of granular solids. The stress-strain relationship is derived for an element of granular...
Simulations of Gravity-Driven Channel Flows of Disks Floating on the Flowing Viscous Fluid
A two-dimensional discrete element model has been applied to the problem of gravity-driven channel flow of uniform disks. The particles are floating on the surface of the flowing fluid...
Interparticle Sliding and Rolling
Numerical experiments are done with a continuum plasticity program in order to study the initiation and evolution of shear bands. Many elements are used in order to resolve families of...
Distant Eyes
A remotely operated vehicle is a miniature unmanned submersible that contains lights, a video camera, other instrumentation, and motor thrusters to move it through the water. The operator,...
Hurricane Retrofit
Houston's Sheraton Hotel and Convention Center has been retrofitted to protect it from panel pop-out (separation from building curtain walls) and curtain-wall separation from...
Safeguarding History
Even monolithic marble monuments, such as the Thomas Jefferson Memorial, fall prey to materials deterioration. Now, sensitive instrumentation systems can document and analyze even the...
Recapturing Boston's Heritage
Structural upgrading of Boston's Old State House and Faneuil Hall is part of an extensive restoration project undertaken by the National Park Service at a cost of $10.6 million...
Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...
Pipeline Rehab: Underground Options
While simply digging up old pipes and replacing them is sometimes still best, other alternatives can give long life while easing the strain on the community. Trenchless methods for on-line...
Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...
Are We Ready to Face the Geotechnical Challenges of the 21st Century?
The geotechnical engineering profession faces a bright future as many of the issues of interest to society today relate in some form to knowledge of earth sciences. Hazardous waste, environmental...
The Pressuremeter: Some Special Applications
The preboring pressuremeter has been used for foundation design for many years. Some recent developments are presented which extend the applications of the pressuremeter. These developments...
Soil-Cement Mixed Wall Technique
This paper introduces the soil-cement mixed wall technique and its applications for the installation of cutoff walls, excavation support walls and soil-crete columns for soil stabilization....
KBES Applications to the Selection and Design of Retaining Structures
Knowledge-based expert systems (KBES) are computer programs, based on artificial intelligence (AI) techniques, designed to reach the level of performance of a human expert in some specialized...
Evaluation of Geotechnical Design Parameters by Expert System Techniques
This study refers to application of an artificial intelligence technique to evaluate geotechnical design parameters in the soil design definition. This complex evaluation is incorporeted...
Use of a Tie-Back Retaining Wall to Stabilize a Moving Landslide
After failure of a gravity retaining wall, a moving landslide was stopped and stabilized by a tie-back retaining wall. The design considered the active landslide and residual strength...
Watertight and Earthquake Resistant Joints for Diaphragm Walls
Different types of joints were constructed and tested in the field to evaluate the bond between concrete and partition plate, the effect of tremie pipe location to the quality of concrete...
Within the North Wall of Hugo (Personal Recollections of Being in the Wrong Place at the Wrong Time)
Our house is in Romain Retreat, a subdivision of lots of 1 1/2 -3 acres in Awendaw, S.C. approximately 20 miles northeast of Charleston off Route 17 and about the same distance from McClellanville...
