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)...

The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...

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...

Dynamic Response Correlation Using Simplified Models
A simplified model for building response which has a W. Ramberg-W. R. Osgood hysteresis is developed in a discrete sense. It is then used to evaluate the response of an instrumented, bearing...

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...

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...

Expansion of the Electro-Coal Transfer Terminal
This paper briefly describes renovation and expansion of the coal and phosphate marine terminal in Davant, La. The program included: replacement of existing berths damaged by marine accident;...

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...

Use of In Situ Tests for Foundation Design on Clay
Years of evaluated experience with the field vane test in soft clays have resulted in empirical correction factors well suited for design practice. An extension of L. Bjerrum's...

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...

Borehole Shear Test and Slope Stability
Three Iowa landslides analyzed on the basis of Borehole Shear Test (BST) data are reported. The soils included CL and ML loess and glacial till, and CH clay shale. Back-calculations from...

Pressuremeter Correlations for Preconsolidated Clay
Conventional triaxial compression and consolidation tests are often utilized to obtain parameters for design of foundations. More recently, Menard pressuremeter test results have been...

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...

In Situ Tests Aid Design of a Cylinder Pile Wall
In situ testing was used to verify geotechnical design parameters and modify construction for a 22 million dollar slope stabilization project near a major highway interchange. The project...

Correlation of Soil Parameters From In Situ and Laboratory Tests for Building 333
Pressuremeter, plate bearing and cone penetration tests were performed on the prepared foundation soil for Building 333 located in the Red River Army Depot near Texarkana, TX. The results...

Pore Pressure Effects in Borehole Shear Testing
The effects of excess pore pressures on shear strength results obtained using the Borehole Shear Test (BST) were investigated. Pore pressures were measured during the consolidation, shear,...
