Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...

Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...

Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...

Effect of Seismic Wave Inclination on Structural Response
A new procedure is developed using the computer program SASSI to evaluate the effects of inclined propagating shear waves on three-dimensional seismic soil-structure interaction (SSI)...

A Stochastic Source Spectrum for Engineering Application
The solution of a point source (double couple) combined with K. Aki/A. S. Papageorgiou's stochastic source model is used to establish the power spectrum at the acceleration...

Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....

Design of Wharf Facilities, Guam, M.I., to Accommodate Difficult Site Conditions
A wharf facility currently under construction in Guam, Mariana Islands, for the U. S. Navy utilizes precast concrete box caisson construction to satisfy difficult site conditions. To reduce...

An OCEANWHEEL Breakwater
The compression wall and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...

Perforated Wave Barriers in Small Boat Piers
Perforated breakwaters can be used to reduce the energy and the height of waves entering small boat harbors. By not extending the breakwater to the bottom interference with littoral drift...

Design Concepts for Floating Breakwaters
This paper describes a fundamental approach to the design of a floating breakwater based on the concepts of dynamic analysis of floating bodies. The process results in a relatively simple...

Ship Wave Prediction for Port and Channel Design
Several laboratory and field investigations of ship-generated waves have been conducted during the past twenty-five years. Typically, for a given ship, reported data consists of the height...

Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...

Seismic Cone Penetration Test
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...

Comparison of the SPT,CPT, SV and Electrical Methods of Evaluating Earthquake Induced Liquefaction Susceptibility in Ying Kou City During the Haicheng Earthquake
The capability of SPT, CPT, Shear Wave Velocity and Electrical methods to evaluate earthquake induced liquefaction susceptibility of soil deposits consisting of sensitive clayey silts...

Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...

Analysis of Liquefaction Potential by Insitu Testing
This paper describes the results of insitu testing performed to assess the liquefaction potential of a sand formation at a site for a proposed large industrial facility in East Central...

In Situ P and S Wave Velocity Measurement
A review of the in situ techniques to measure P and S wave velocities by seismic wave propagation is presented. A relatively new technique, the suspension PS logging method, is described...

North American Standard Penetration Test Practice: An Essay
The Standard Penetration Test (SPT) is the in situ mechanical soil test most used by North American geotechnical practitioners. The equipment and procedures of the test have periodically...

Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...

Sediment Penetration in Lakes as a Result of Dredged Material Disposal and River Sediment Loads
Pollutant transport within the coastal boundary layer is highly sensitive to the vertical current structure and to the magnitude of the vertical current, especially during upwelling and...
