Graham Lake Dam Remedial Measures Project
Graham Lake Dam consists of a 550-foot long earth embankment and an 80-foot long concrete spillway. Several concerns were identified during project inspections including limited spillway...

Remedial Design and Construction to Improve a Sliding Embankment
The paper describes the studies made to identify the nature of possible remedial measures such as improved drainage, removal of the weak clay layer or a provision of a buttressed dam....

Seismic Stability Modification Designs for Embankment Dams
The Bureau of Reclamation (Reclamation) has recently designed rehabilitations for four embankment dams to ensure their seismic stability. A fifth project is scheduled for construction....

Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...

Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...

Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...

A Structural Engineering Education Image Database
An interactive multimedia environment has been developed to allow students and instructors access to digital images from case studies of structures and structural failures. In this multimedia...

Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...

A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...

Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...

Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...

A Graphics-Based System for Urban Roadway Management
This paper describes a graphics-based system for urban roadway management. The main objective of the system is to select the cost effective maintenance and rehabilitation (M&R)...

Large Truck Impacts on the Highway Infrastructure: The Bridge Dimension
Recent U.S. studies have explored the productivity gains of longer combination vehicles (LCV's) and their impacts on highway infrastructure. The area least explored is LCV operations and...

Estimating the Ground Transportation Impacts of the Maglev System
This paper will examine the planning process required to conduct a transportation analysis for a high speed ground transportation system, utilizing the Orlando experience as an example....

Storm Sewer Analysis & Design Utilizing Hydrographs
In this paper a computer model, designated STORM.HYD, for the analysis and design of storm sewer systems utilizing a hydrograph procedure is presented and discussed. This model which actually...

Stream Stability and Scour Training in Support of the NBIS
The Federal Highway Administration is now requiring a comprehensive evaluation of bridge scour as part of the National Bridge Inspection Standards (NBIS). To support the implementation...

Implementation of the NBIS Scour Evaluation Program?District 2, Florida
The Federal Highway Administration is now requiring a comprehensive evaluation of bridge scour as part of the National Bridge Inspection Standards (NBIS). District 2, Florida Department...

The Pipe/Soil Stiffness Ratio Variable
This paper reviews the factors which affect the reactions and defines performance limitations of buried flexible plastic pipe as a function of load-induced strains and deflections. The...

Ovality in Pipe Rehabilitation Design
Pipes in need of structural rehabilitation often have longitudinal cracks (at the crown and elsewhere) and exhibit significant ovality (5-10%). When these pipes are lined with current...

Microtunneling with PVC Pipe
PVC is a suitable and economical product for sewer system construction. However, in the past, utilization of PVC sewer pipe in microtunneling was impossible due to axial thrust load limitations...
