Performance Monitoring of Concrete Structures with Embedded Sensors
This paper describes the use of embedded fiber optic sensors to monitor the performance of reinforced concrete structures. The fiber optic sensors are capable of measuring vibrations,...
How to Optimize Reinforced Concrete Systems
A straightforward procedure for the optimization of member dimensions and reinforcement design in concrete structures consisting of beams, slabs, and columns is presented. The procedure...
How to Optimize Prestressed Concrete Systems?
Three common problems of prestressed concrete optimization, that involve only a single structural analysis and can readily be solved by available programs, are presented: 1. The problem...
Rock Structure in Relation to Concrete Dams on Granite
Granite is often considered to provide an excellent foundation for a concrete dam and a great many dams are thus founded on granitic rocks. Although granitic rocks lack the bedding of...
Numerical and Centrifuge Modeling of an Arch Dam on Jointed Rock
This paper addresses the stability of an arch dam built on highly fractured argillite. A large concrete thrust block combined with a wing dam forms the left dam abutment. The last FERC...
Three-Dimensional Stability Analysis of Carpenter Dam
This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect...
Reliability Analysis of Navigation Structures
Methods for probabilistic stability analyses of concrete monoliths at hydraulic structures were developed and tested. Numerous analyses were performed using data from six actual structures...
Roller Compacted Concrete for Embankment Overtopping Protection
In the first National Dam Safety Inventory and inspection performed by the Corps of Engineers, the majority of deficiencies found were related to the inability of the project to retain...
Construction of CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) systems have been installed as overtopping protection on three small embankment dams along the Blue Ridge Parkway. Based on field tests by others and on the...
Saylorville Spillway: Emergency to Service Spillway
The spillway for Saylorville Lake located on the Des Moines River, 12 miles north of the city of Des Moines, Iowa, a large metropolitan, was designed as an emergency spillway. Due to subsequent...
Mud Mountain Dam Concrete Cutoff Wall
Mud Mountain Dam is an earth and rockfill flood control dam on the White River. The dam is located approximately 50 km southeast of Seattle, Washington. The dam was constructed in 1941...
Landslide Stabilisation at the Clyde Power Project, New Zealand
The Clyde Power Project is a hydro electric development on the Clutha River in the South Island of New Zealand. A wide range of stabilization measures have been used to treat several large...
The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...
Bond Stress Test on Rock Anchor in Clayey Siltstone
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...
Rehabilitation of Crescent and Vischer Ferry Dams?Construction Techniques & Problem Solutions
This paper reviews some of the problems encountered during the rehabilitation of the Crescent & Vischer Ferry Dams and the techniques used to comply with strict water level regulations...
Prestwood Lake Dam Rehabilitation
The Prestwood Lake Dam located in Hartsville, South Carolina is owned by Sonoco Products Co. It originally was a wood structure built in 1895. That structure was washed out by a hurricane...
Testing and Evaluation of High Capacity, Multi-Strand Rock Anchors for Lake Lynn Dam
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
Conversion of a Concrete Slab and Buttress Dam to a Gravity Dam
The 58-foot high, 425-foot long, Ambursen-type, concrete slab and buttress, Gorge Plant Dam, which has a 120-foot long overflow spillway near the center, was converted to a concrete gravity...
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...
