Strengthening Alaskan Beaufort Sea Soils with Portland Cement
Preliminary studies undertaken to assess the feasibility of utilizing gravity structures on soft arctic silts indicate that the available foundation capacity are insufficient. Therefore...
Sampling and Testing in Stiff Crustal Clays
In desiccated clays, the secondary structure consisting of fissures and slickensides greatly influence the measurement of soil strength. In a sampling study, such soils were found to be...
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...
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...
Attaching Steel Members to Reinforced Concrete Elements
A variety of structural systems have been devised to strengthen existing buildings for improved seismic resistance. Strengthening methods currently in use for reinforced concrete structures...
Strengthening of a Multi-Story Building with Deflection Constraints
Occasionally the existing structural or nonstructural systems of a building being strengthened require the imposition of deflection constraints or limits in order to avoid an undesirable...
Flexural Behavior of Reinforced Masonry Walls and Beams
Many reinforced masonry walls and beams were tested as a part of the U. S. -Japan cooperative research program on masonry building structures. Six concrete block and two clay brick masonry...
Research on the Strength Characteristics of Timber Piling
Research on the strength characteristics of wet Southern Pine and Douglas Fir piling and poles is presented. Included are background information on wood's strength characteristics,...
The Mile High Dream
For the 1986 Tall Buildings Conference in Chicago, a group of experts studied the implications of a mile high skyscraper to be built of concrete. It is 500 ft square at the base, designed...
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...
ECPT Investigation of a Slurry Trench Cutoff Wall
ECPT (electronic cone penetration testing) was used to investigate a soil-bentonite backfilled slurry trench cutoff wall at Calamus Dam in Nebraska, The wall was tested shortly after its...
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...
Strength of Fine-Grained Soils Using the Piezocone
Evaluation has been made of several theories and methods for deducing the undrained and effective stress strength of saturated fine-grained soil from piezocone test results. Bearing capacity...
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,...
Determining Sand Strength by Cone Penetrometer
