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...
Analysis
This section presents theoretical and practical concepts for the analysis of guyed transmission structures. The concepts are further illustrated in the examples of Section 8. The term...
Small Inocula Can Effect
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...
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...
Implementation of Watershed Planning in Chester County Pennsylvania
The author presents portions of a study into the current watershed regulatory framework in Pennsylvania, and how effectively this framework supports watershed sustainability when faced...
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...
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...
The Northridge Fractures: Are We Learning the Right Lessons?
After the Northridge earthquake in January 1994, engineers found problems with special moment-resisting frames. There were multiple facture modes, and typical damage involved primary crack...
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,...
Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...
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...
