Geotechnical Innovations: Why Seldom Used in Highways?
Ground improvement methods introduced within the past decade to American geotechnical engineers offer cost savings, ease of construction and reduced construction time. Amont these innovations...
ACI 349 Embedments: Code Provisions and Methods of Analysis
Steel embedments form the critical link between steel and concrete structures. Appendix B of ACT 349, Code Requirements for Nuclear Safety Related Concrete Structures, specifies the ultimate...
Vertical Behavior of Two 16-Year Old Drilled Shafts
Vertical load tests were performed on drilled shafts subject to lateral confining and heaving pressures from expansive soil over 16 years. Results indicated mobilized skin friction equal...
Consolidation-Strength Analysis for Soft Soils
A one-dimensional consolidation analysis including prediction of consequent shear strength increase for soft soils which exhibit large secondary compression is proposed. Consolidation...
Plunge Pool Erosion in Cohesive Soils at Two Dams in Kansas
Results of a field study of two plunge pools scoured by horizontal pipe outlets discharging on cohesive channels are analyzed. Formulas for critical tractive shear stress based on plasticity...
Cavitation in Various Types of Shear Flow
Cavitation in turbulent shear flow depends on the intensity and spectral characteristics of the pressure fluctuations in a Lagrangian frame of reference as well as depending on the concentration...
Restoration
After the San Fernando earthquake of 1971, California's State Capitol Building was declared an earthquake hazard and vacated. It took the most extensive structural and architectural...
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
Directional Wave Spectra Applications
These collected papers and their ensuing discussions presented at the September, 1981 symposium at the University of California on directional wave spectra applications examine the present...
Steel Plate Shear Walls Resist Lateral Load, Cut Costs
Two new buildings have a seldom-used stiffening system�� steel plate shear walls. Reasons for using them, rather than reinforced concrete shear walls or steel or concrete rigid frames,...
Los Angeles Reservoir is Safe From Earthquakes
The Los Angeles Reservoir was nominated for the 1978 Outstanding Civil Engineering Achievement Award. The reservoir, which replaces the Van Norman Reservoir damaged during the 1971 San...
Modern Concrete Structures Survive Romanian Earthquake
On March 4, 1977, 35 buildings collapsed during a severe earthquake (7.2 on the Richter scale) in Bucharest, Romania. Thirty-two of the 35 were older structures, erected before World War...
Pitfalls of Overconservatism in Geotechnical Engineering
The article cites at least three reasons why geotechnical engineers may be overconservative: (1) They may try to satisfy unreasonable standards established by themselves or others; (2)...
Methods of Structural Analysis
Proceedings of the National Structural Engineering Conference, Methods of Structural Analysis, an ASCE Structural Division Specialty Conference held at the University of Wisconsin, Madison,...
Bailey's Crossroads: A/E Liability Test
In March 1973, a 24-story reinforced concrete building under construction at Bailey's Crossroads, Va., partially collapsed causing a total collapse of an adjoining parking...
Stability of Rock Slopes
Proceedings of the Thirteenth Symposium on Rock Mechanics held at the University of Illinois, Urbana, Illinois, August 30 September 1, 1971. Sponsored by the U.S. National Committee for...
Research Conference on Shear Strength of Cohesive Soils
Proceedings of the Research Conference on Shear Strength of Cohesive Soils, held at the University of Colorado, Boulder, Colorado, June, 1960. Sponsored by the Soil Mechanics and Foundations...
