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...
High Over Shanghai
In response to difficult design conditions, Shanghai's Jin Mao Tower's structural system harmoniously mixes building materials and strategically places them to...
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...
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...
Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...
Microgravity Research in a Space Station Environment
A broad class of scientific experiments have evolved which utilize extreme low acceleration environments. A space station can provide such a `microgravity' environment, in conjunction...
Wheel Space Station for 2025
The advantages and disadvantages of three basic space station designs are discussed. These designs are a zero-gravity can like Skylab, a tethered system, and the wheel. A design of a wheel...
The Effect of Zero Gravity on Bones
Zero-gravity has created many problems for astronauts and researchers in space. Calcium depletion is cited as a major health problem. There are many different theories as to why zero-gravity...
Seismic Behavior of Type PR Steel Frames
Type PR(partially restrained 'simple framing') is one of the methods of design specified in the AISC LRFD(1986) Design code for the design of unbraced steel building frames. In this method...
Seismic Behavior of Non-Ductile Concrete Frame Structures
Non-ductile reinforced concrete (RC) frame structures designed and constructed during the 1950's through 1970's exist in many regions of the United States. The frames of these structures...
Review of Cold-Formed Steel Purlin Design
The use of cold-formed steel members as roof purlins for single story industrial and commercial buildings is commonly recognized. These members typically have either a C- or Z-shaped cross...
Buckling of Single Layer Latticed Dome under Uniform Gravity Load
This paper reports on experiment and numerical analysis relating the buckling of a single layer latticed dome under uniformly distributed nodal gravity load at the dome central portion....
Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...
Nonlinear Earthquake Analysis of Concrete Gravity Dams Including Sliding
The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
On the Generation of Infragravity Waves by Shoaling Multidirectional Waves
The generation of long period waves in shallow water by shoaling multidirectional waves is investigate using both numerical simulations and laboratory experiments. The numerical model...
Measured Total Wave Climate of a Small Craft Harbor
Measurements of waves in a small craft harbor were analyzed for the purpose of determining the existing wave climate energy levels causing the excessive agitation of moored small craft...
