Location of Geologic Discontinuities by Geophysical Techniques
An overview of the seismic refraction method and resistivity methods is given. These two geophysical techniques are integrated into a systematic method for locating geologic discontinuities...
Ground Failure Damage to Buildings During Earthquakes
Several case histories are examined to evaluate building damage as a function of the foundation type and type and amount of ground displacement. Extensional or vertical ground displacements...
Effect of Site Soil Properties on Seismic SSI Response of Embedded Structures
In a series of two-dimensional soil-structure interaction (SSI) analyses, seismic responses, including the SSI effect of a deeply embedded reactor building of a standard plant in different...
Seismic Response Study of Two Memphis Sites
This paper presents a study to evaluate the soil effects on earthquake ground motion of two selected sites in the Memphis area. Twenty artificial bedrock acceleration time histories with...
Simplified Seismic Analysis of Pile Foundations
The determination of displacement of the pile cap and displacements and forces of individual piles is essential to the design of pile foundation subject to both static and/or dynamic loading....
Seismic Response Considerations in Foundation Design
There are no generally accepted procedures to determine the potential magnitude of reduction of footing bearing capacity that may result from soil strains or pore pressure changes during...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Nondestructive Testing of Deep Foundations with Sonic Methods
Nondestructive testing and evaluation (NDT&E) of deep foundations with three sonic methods is discussed. Case history investigations described include test records from drilled...
Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. The...
Management of Drumstick Barrier Islands
Three major problem areas exist on these barrier/inlet systems: 1) the updrift inlet which tends to migrate and erode the upland barrier, 2) the narrow, low and sediment-starved downdrift...
Sediment Transport Processes at Sandbridge, VA
Sandbridge Beach is a primarily residential community located along a 7 km reach of narrow barrier beach. Rates of erosion in this area historically have been high, reaching as much as...
Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...
Recent Erosion in the Stable Ipanema-Leblon Beach in Rio De Janeiro
This paper presents the findings of a diagnostic study contracted by the City Hall of Rio de Janeiro, concerning beach erosion problems. It first reviews the problem and existing data....
Computer Utilization in Structural Engineering
This volume contains the papers presented at the 1989 Structures Congress sponsored by the Structural Division of the American Society of Civil Engineers that deal directly with the application...
Seismic Engineering
Research and Practice
This volume of Seismic Engineering: Research and Practice contains papers from twenty-two sessions of the 1989 ASCE Structures Congress. These papers represent a wide-ranging interest...
Steel Structures
The seventy-eight papers included in this volume cover the fifteen sessions generally associated with steel structures presented at the Seventh Annual Structures Congress held on May 1-5,...
Potential Flow Over a Wavy Bed: A Persistent Error
The standard small-amplitude theory of potential flow over a wavy bed is briefly discussed, together with the three special values of the Froude Number which define four different flow...
Bed Waves Generated by Internal Waves in Alluvial Channels
The flow in an alluvial channel is conceived as a stratified flow both with respect to the velocity- and density-distribution. In such flows internal waves may occur which influence the...
Modelling of Sand Bars in Coastal Environments
A mathematical model describes the formation of sand bars by progressive wind-generated waves. The model decomposes into several constituents linked together in a two step morphological...
A Method to Treat Incident Wave Condition in Shallow Water Equation
A method to consider open boundary condition of the shallow water equation to analyze water surface wave and tide is employed in the finite element anaysis. This can be done by considering...
