Failure Characterization of Structural FRP Bars
A combined experimental and theoretical investigation on the structural behavior of fiber reinforced plastic (FRP) bars is presented. Test results indicate that the ultimate strength decreases...

On the Design of Laminated Composite Flange: A Model with Experimental Verification
A parametric model has been developed for the optimum design of laminated composite flange. The study focuses on the evaluation and performance optimization of composite flanges with the...

Bond Strength of Reinforcing Bars in SIFCON
This paper presents a brief summary of an ongoing investigation on the bond characteristics of deformed reinforcing bars embedded in a SIFCON matrix. A significant increase in bond strength,...

Simulation of Failure Processes in Cementitious Particle Composites
Progressive failure analysis in cementitious particle composites such as concrete requires a realistic description of the topology of the composite structure and the interaction of the...

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...

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...

Geotechnical Database Management Systems for Boston's Central Artery/Harbor Tunnel Project
This paper presents a geotechnical computer application currently in use on Boston's Central Artery/Harbor Tunnel (CA/T) Project. The application is designed to manage subsurface...

A Hybrid Expert System for Design with Geosynthetics
A prototype hybrid expert system is presented that selects geosynthetic materials and performs detailed designs for different geotechnical applications. An expert system is used to give...

Geotextile Edge Drain Design and Specification by Expert System
Expert systems can be developed and operated on personal computers to aid in the design of the geotextile filter component of pavement edge drains. The expanding use of geotextiles in...

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....
