Japan Studies Floating Airport (Available only in Structural Engineering Special Issue)
Floating airport structures are being studied in Japan. Because of a severe shortage of land, the Japanese and U.S. governments are considering floating structures for civilian and military...
Historic Upgrades in San Francisco
The 1989 Loma Prieta earthquake seriously damaged many of the historical buildings that compose the San Francisco Civic Center complex. As the complex serves as a critical cultural and...
Old Aswan Dam
Egypt's Aswan Dam is almost 100 years old, and engineers performed tests of the masonry, conducting petrographic and chemical analyses. The High and Aswan Dam Authority of...
Numerical Modeling of Water Flow over Porous Media
The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the...
Synchronized Measurements of Bed-Shear Stress and Flow Velocity in Open Channels with Simulated Vegetation
Synchronized measurements of shear stresses at the bed and velocities both within and above a simulated plant canopy in an open-channel flow are presented. Traditional (hot-film sensors)...
Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...
Two- and Three-Dimensional Hydrodynamic Modeling of the Salton Sea, California
The Salton Sea, the largest surface water body in California, faces a myriad of problems related to rapidly changing water levels, rising salinity, accelerated eutrophication, fish kills,...
Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...
Seismic Design Doubles Lateral Resistance (Available only in
A veterans hospital in Palo Alto, Calif. had to be built under severe design constraints. The seismic code for hospitals is among the most stringent of codes and this facility was sited...
Engineered Contaminated Soils and Interaction of Soil Geomembranes
Due to liability issues, landfills are no longer considered the best method of waste disposal. Innovative, safe disposal methods for large quantities of contaminated soils and waste are...
Wave Forces on Inclined and Vertical Wall Structures
This monograph,
Rock Steady
Heavily damaged during the Loma Prieta earthquake, Oakland City Hall had to be repaired and retrofitted. Now Oakland boasts the tallest seismically isolated building in the world. The...
Static and Dynamic Properties of Gravelly Soils
The behavior of gravelly soils has been the focus of much research in recent years. Large-scale penetration and triaxial tests, shear-wave velocity measurements, insitu freezing and sampling,...
On the Dynamics and Control of Flexible Orbiting Systems: An Approach with Application
A relatively general formulation for studying the dynamics and control of an arbitrary spacecraft, with interconnected flexible, deployable and articulating structural members, is reviewed...
Modal Interaction in the Response of Laminates
A higher-order shear-deformation theory is used to analyze the interaction of two modes in the response of thick laminated rectangular plates to transverse harmonic loads. The case of...
Postbuckling Response of Doubly-Curved Shallow Panels Under Complex Loading Conditions
The static postbuckling of laminated doubly-curved shallow panels subjected to the complex action of a system of in-plane compressive edge loads and a transverse pressure field is investigated....
Snap Buckling of a Delaminated Layer in a Composite Cylinder
We investigate snap buckling of a thin delaminated layer on the inner surface of a contracting thick cylinder. Finite-deflection solutions of the layer with or without considering the...
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...
