Probabilistic Model for Stability of Slopes
Presented herein is a probabilistic model based on derived distributions to predict shear strength of soils and the safety factor of slopes considering uncertain properties of soil, namely:...
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
Pressures on Prisms in Turbulent Shear Flows
Experimental results are presented which show that Melbourne's 'Small Scale Spectral Density Parameter,' S, controls the negative pressures on the...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
Stable Channels with Loose Boundary
Recently, G. Parker suggested that the lateral transport of downstream momentum due to Reynolds stresses should be included in the momentum balance used to calculate the boundary shear...
Microstructure of Cohesive Sediment Suspensions
In a shear flow field suspended fine sediments under relatively low concentrations and stable stratification conditions develop a step-wise profile. This is due to internal wave instability...
Prediction of Scour Depth Under Armoring Conditions
A simple procedure is proposed to compute scour depth on an alluvial bed having graded materials under flow conditions which produce armor layer at the bed surface. The procedure is based...
Measurements of Mean Velocity, Turbulence and Temperature in a Deflected, Heated Water Jet
A submerged heated water jet issuing from a vertical wall into a turbulent flow in a rectangular open channel is investigated experimentally to determine the mean velocity, turbulence...
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Solutions to Space Station Designs
Any space station that is to be designed for extended human use may require gravity. The artificial gravity field required can be produced by rotating the structure. As the Soviets have...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Preliminary Dynamic Analyses of the Ministry of Agriculture Building
The Ministry of Agriculture building on Avenida San Antonio Abad was originally constructed as a 17 story reinforced concrete structure using a waffle slab system with interior reinforced...
Implications of Structural Characteristics on Failure
Performance of buildings with two common structural types, many of which suffered heavy structural damage or collapse, are analyzed. Conclusions are drawn that no structural type is inadequate,...
Seismic Rehabilitation: Why, When and How
Common methods of seismic rehabilitation are: repair of cracks, reconstruction of structural elements, addition of stiffening elements, and addition of dampers. A major consideration is...
Cause and Elimination of the Deflation Zones Along the Atlantic City (New Jersey) Shoreline
After recent construction of several large hotels and apartment buildings directly fronting the Atlantic City boardwalk, large blowouts were observed to occur during the winter season...
U.S. Coast Guard Experience with Wave Turbines
Since 1980 the United States Coast Guard has been developing a lighted buoy for exposed areas and congested harbor entrances. The buoy hardware is of conventional design while the signal...
Geotechnical Properties and Landfill Disposal of FGD Sludge
Extensive test data from more than a decade of research are compiled on the geotechnical engineering properties of flue gas desulfurization (FGD) sludges with emphasis on double alkali...
Computer Aided Simulation of Fluid-Structure Interaction Problems
The papers included in this book represent state-of-the-art developments in and applications of computer aided simulation of fluid-structure interaction problems in both the terrestrial...
Flow Around Islands in Rupert Bay: An Investigation of the Bed Friction Effect
Aerial photographs of transverse shear flows around islands in Rupert Bay, a shallow and turbid estuary in northern Quebec, were studied for effect of bed friction. The island wake depends...
