Measuring the Spatial Characteristics of Unsteady Pressures
This paper has reviewed current methods of determining spatially-averaged time-varying wind loads on wind tunnel building models. Some of the possibilities opened by simultaneous multi-channel...
Field Experiments for Wind Pressures
A project is underway at Texas Tech University to acquire wind and building surface pressure data in the field. Objectives of the project are to obtain a reliable data base for external...
Sewers Get a Breath of Fresh Air
Domestic sewage pump stations and treatment facilities have long been plagued by corrosion and odor problems caused by hydrogen sulfide. It is also extremely toxic. Sulfide production...
Wave Energy Research in Ireland
Measurements taken at several locations off the Irish coast show that the average power intensity available to Ireland well exceeds 20 kW/m. Several projects have been undertaken in an...
Solution to a Waterhammer Problem: A Case Study
Waterhammer is caused by a rapid change in the flow velocity of liquid in a pressurized pipeline. Therefore, the potential for waterhammer exists in almost every pressurized liquid piping...
Milan's Model Metro
A number of innovative geotechnical methods were used at the extension of the Milan, Italy, subway. Jet grouting, a technique used only a few times in the United States, was notable among...
Shake-Proof Dams
Seismic trouble spots in California and along the Pacific Coast usually get the most publicity. But many people don't realize that Wyoming, Illinois, South Carolina, Utah...
Leakage from Pressure Tunnels and Shafts
Several issues related to leakage from unlined pressure tunnels and shafts are reviewed and discussed. They include confinement, or cover requirements relative to hydraulic jacking of...
Analysis and Testing of Transient Pressures at Camp Far West Hydroelectric Project
The objective of this paper is to present a comparative discussion of the results of theoretical analysis of transient pressures and of field tests performed on the Camp Far West Hydroelectric...
Monitoring Techniques for Thermosyphons
Two-phase thermosyphons used for passive soil refrigeration are monitored using a variety of techniques ranging from visual infrared scanning to measurement of internal pressures. Methods...
Lateral Pressure in a Stiff Clay
A series of consolidated undrained and drained triaxial tests and oedometer tests were performed on horizontal and vertical specimens taken from an overconsolidated cretaceous clay. An...
Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...
Excavation in Hard Clays of the Keuper Formation
For the construction of a lock on the Main-Danube-Canal in South Germany a 30 m deep cut had to be excavated in the overconsolidated clays and claystones of the Keuper formation. The strength...
New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
Cladding Design for Tall Buildings
In the past twenty years, glass cladding has emerged as a popular and economic building material. Its use in tall buildings which are constructed in high-risk wind and seismic geographical...
Pressuremeter and Shallow Foundations on Sand
The settlement and bearing capacity rules for the design of shallow foundations on sands using the results of pressuremeter tests are reviewed. The results of four footing tests to failure...
Seismic Design of Earth Retaining Wharf Structures
Seismic design considerations pertinent to earth retaining wharf structures are reviewed. These considerations include: evaluation of the seismic environment and design earthquake ground...
Deformation Characteristics of Cohesionless Soils from In Situ Tests
This paper is a summary of seven years experience gained by the National Electricity Board of Italy (ENEL), ISMES and Technological University of Turin in assessing these parameters using...
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...
Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
