Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
Success or Failure: A Tale of Two Projects
Twenty city blocks and a ten year period separated two projects of similar purposes, but with completely different endings. The first one, the Delancey Street Project, took place in 1984...
Engineering Mechanics
This proceedings contains keynote and summary papers presented at the 11th ASCE Engineering Mechanics Conference held in Fort Lauderdale, Florida, May 20-22, 1996. The keynote papers address...
Quake Proofing a Palace
A $36.5 million renovation of the California Palace of the Legion of Honor included a two-level underground expansion on a very sensitive site and the largest-ever seismic retrofit for...
Uncertainty in the Geologic Environment
from Theory to Practice
The state-of-the-art is presented with respect to analytical and design methods incorporating uncertainty in the geologic environment. Particular emphasis is placed on practical applications...
Sound Way to Save Fish
Fish protection need not cost an arm and a fin. Using light and sound to spare fragile blueback herring and other species a harrowing fate, the U.S. Army Corps of Engineers devised a fish...
Asphalt-Concrete Water Barriers for Embankment Dams
Because of its simplicity in design and construction, the asphalt concrete core is rapidly becoming the water barrier of choice for embankment dams in many parts of the world. This is...
Lessons From Kobe
On Jan. 17, Kobe, Japan became the first post-World War II, heavily populated, industrialized area to bear the full brunt of a high-magnitude earthquake. Engineers hope the resulting destruction...
Failures in Civil Engineering
Structural, Foundation and Geoenvironmental Case Studies
This special publication consists of a collection of short descriptions of failures case studies in Civil Engineering. The descriptions cover cases in structural, foundation and geoenvironmental...
Hydraulic Design of Spillways
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 12. This manual presents guidance for the hydraulic...
Divided We Fall
This article examines the aftermath of a falsework failure during the construction of a Mississippi River bridge in Minnesota. The author reviews the legal issues that arose from the collapse,...
Do Civil Engineers Have an Ethical Responsibility to their Client at the Expense of the Environment?
The application of engineering ethics to the environment is at the center of the debate regarding sustainable development. If the environment is to be held above client needs, say many,...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
Design Techniques for Rectangular Lunar Modules
This paper discusses relevant issues concerning the design and performance of cubical lunar modules. Previously, these modules have shown to be a possible solution for living and working...
Mechanics of Curved Fiber Bundles in Composites
Fiber undulations are inherent to manufacturing processes like braiding and filament-winding, and sometimes occur as defects in other composite structures. This paper summarizes the status...
Implementation of a Viscoplastic, Kinematic Hardening Constitutive Model for Impact Prediction
This paper reports on a preliminary study to determine the significance of the Bauschinger effect on modeling impact and other large deformation events. Such events have significant implications...
Nonlinear Collapse of Offshore Jacket Structures
The Joint Industry Tubular Frames Project was established with ten oil industry sponsors to investigate the reserve and residual strength of frames typical of offshore structures. To date...
Comprehensive Reliability Analysis of Prestressed Concrete Beams
Using second moment methods, the reliability with respect to several limit states for seventy three prestressed concrete beams is assessed. These beams that are extensively used in the...
Human Error Models for Structural Reliability
This paper presents models for human errors to be used along with reliability analyses. The models account for the occurrence of errors, their magnitude, and the detection of the errors....
Steel Compression Member Design in the 1994 Canadian Standard
The 1994 edition of CSA Standard S 16.1-M94, Limit states design of steel structures (CSA 1994) contains explicit methods for computing the compressive resistance of monosymmetric and...
