Damage Detection in Periodic Structures
Nondestructive damage detection in periodic structures using continuum analogues of the discrete structure is studied. Algebraic equations relating changes in eigenfrequencies to the fractional...
Cyclic Simple Shear, Torsional Shear and Triaxial�A Comparative Study
Many different testing apparatus are used to duplicate in laboratory soil samples the stress state generated in situ by earthquakes. A wide diversity of data has been generated and this...
Uplift Behavior of Shallow Soil Anchors?An Overview
An overview is presented of the static uplift (tensile) behavior of shallow anchors used for foundations in soil. Basic anchor types are described, and their general installation and behavioral...
Uplift Capacity of Shallow Offshore Foundations
Soil failure under upward loading is investigated by experimental laboratory tests. The problem of uplift capacity is considered in terms of effective stresses in soil skeleton and pore...
Resistance of Shallow Inclined Anchors in Clay
Some recent laboratory model test results for the ultimate pullout resistance of a square anchor inclined at angles of 0, 20, 50, 75, and 90 degrees with respect to the horizontal have...
New Cables for Old
In an eingineering first, the main suspension cables will be replaced on New York City's Williamsburg Bridge without closing it to traffic at any time. According to the design...
Hurricane Alicia
One Year Later
In the pre-dawn hours of August 28, 2983, Hurricane Alicia ripped its way ashore at the western tip of Galveston Island and moved northward to the Greater Houston area. This storm caused...
Composite and Mixed Construction
Steel and reinforced concrete are frequently combined in composite or mixed structural systems. This combination generally results isn greater economy and safety than could be achieved...
Coastal Zone '85
Coastal Zone '85 was a multidisciplinary conference for professionals, interested citizens, and decision-makers to exchange information and views. Coastal zone management...
Performance of Cogoti Dam Under Seismic Loading
At the time of its completion in 1938, the 280 ft (85 m) high Cogoti concrete face rockfill dam was exceeded in height by only one other dam of its type in the world, Salt Springs Dam....
The Outardes 2 Concrete-Faced Rockfill Dam
The main dam of the Outardes 2 development consists of a rockfill embankment, built against an old water-retaining structure, and faced with an upstream concrete membrane. The interface...
Foz do Areia Dam?Design, Construction, and Behaviour
The 525 ft (160 m) high Foz do Areia dam in the Iguacu River, Parana, Brazil, built by 'Companhia Paranaense de Energia - COPEL', between 1975-1980, is part of...
Design Features of Salvajina Dam
Salvajina dam is the second highest concrete face rockfill dam currently in service in the world. The characteristics of the foundation of the toe slab vary from fresh, sound and little...
Design and Construction of Terror Lake Dam
Terror Lake Dam is a central feature of the 189 million Terror Lake Hydroelectric Project, located on Kodiak Island Alaska. The dam is a 193-feet (59 m) high concrete-faced zoned rockfill...
Kotmale Dam and Observations on CFRD
A concrete faced rockfill dam was the type selected for the 300 ft (90 m) dam at Kotmale in Sri Lanka for reasons of economy and speed in construction. Standard design concepts were tailored...
Seismic Design of Concrete Faced Rockfill Dams
The results of analytical studies of the stability of the slopes of concrete-faced rockfill dams under different levels of earthquake shaking are presented and used to propose desirable...
Seismic Analysis of Concrete Face Rockfill Dams
In this article, the observed behavior of existing rockfill dams during earthquakes is compared with published data regarding the estimated seismic performance of several recently designed...
Design and Stability Evaluation of Balsam Meadow Dam
The proposed Balsam Meadow Dam is a 126 feet high concrete-faced rolled rockfill dam currently under construction for the Balsam Meadow hydroelectric project in California. Detailed field...
Design of Deer Creek Dam
The Deer Creek Dam is proposed to be a concrete face rockfill structure (CFRD) with upstream and downstream slopes nominally 1. 3 horizontal to 1 vertical. The embankment will rise 280...
Rockfill Compression Tests and Other Aspects of the Design of Miel I Dam
The Miel I Dam, a high concrete face rockfill dam, is one of the main structures designed for the Miel I Hydroelectric Project in Colombia. Selection of dam type was based on technical...
