In-Situ Shear Strength Testing
Dam stabilization requirements at the Upper Mechanicville Hydroelectric Project on the Hudson River in New York were significantly modified based on the results of an in-situ direct shear...
Comparison of Joint Shear Strengths for Conventional and Roller Compacted Concrete
Direct shear test data for parent material and bonded and unbonded jointed specimens of conventional and RCC (roller compacted concrete) are presented and compared. Results are discussed...
Mechanisms of Subsidence Induced Damage and Techniques for Analysis
Structural damage due to mining induced subsidence is a function of the nature of the structure and its position on the subsidence profile. A point on the profile may be in the tensile...
Probabilistic Model for Stability of Slopes
Presented herein is a probabilistic model based on derived distributions to predict shear strength of soils and the safety factor of slopes considering uncertain properties of soil, namely:...
Simulation with Ordered Discrete-Stochastic Samples
In order to account for the viscoplastic deformations, leading to the failure of structures, the nonlinear dynamic responses can be obtained with convenient spatially discretization schemes....
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Pressures on Prisms in Turbulent Shear Flows
Experimental results are presented which show that Melbourne's 'Small Scale Spectral Density Parameter,' S, controls the negative pressures on the...
Monitoring the Effects of the Pipe Insertion Machine Technique
The results of an experimental study of the pipe insertion machine are presented in this paper. Strains induced in an adjacent pipeline, soil displacement, pipe deflection and vibrations...
Stable Channels with Loose Boundary
Recently, G. Parker suggested that the lateral transport of downstream momentum due to Reynolds stresses should be included in the momentum balance used to calculate the boundary shear...
Microstructure of Cohesive Sediment Suspensions
In a shear flow field suspended fine sediments under relatively low concentrations and stable stratification conditions develop a step-wise profile. This is due to internal wave instability...
Prediction of Scour Depth Under Armoring Conditions
A simple procedure is proposed to compute scour depth on an alluvial bed having graded materials under flow conditions which produce armor layer at the bed surface. The procedure is based...
Measurements of Mean Velocity, Turbulence and Temperature in a Deflected, Heated Water Jet
A submerged heated water jet issuing from a vertical wall into a turbulent flow in a rectangular open channel is investigated experimentally to determine the mean velocity, turbulence...
Differential Gravitional Forces on Large Space Structures
Effects of the differential gravitational forces have been investigated simultaneously on the orbital motion, attitude motion, and axial deformation of a very large axially flexible space...
Thermal Effects on Large Space Structures with Fixed Attitude
Radiation thermal effects are studied simultaneously on the orbital motion and axial deformation of a very large axially flexible space structure executing planar pitch motion around the...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Preliminary Dynamic Analyses of the Ministry of Agriculture Building
The Ministry of Agriculture building on Avenida San Antonio Abad was originally constructed as a 17 story reinforced concrete structure using a waffle slab system with interior reinforced...
Implications of Structural Characteristics on Failure
Performance of buildings with two common structural types, many of which suffered heavy structural damage or collapse, are analyzed. Conclusions are drawn that no structural type is inadequate,...
Seismic Rehabilitation: Why, When and How
Common methods of seismic rehabilitation are: repair of cracks, reconstruction of structural elements, addition of stiffening elements, and addition of dampers. A major consideration is...
Settlement of Residual Soils
The method previously suggested by the author in 1977 for calculating settlement of non-plastic to slightly plastic Piedmont Physiographic Region residual soils is reviewed. Additional...
Geotechnical Properties and Landfill Disposal of FGD Sludge
Extensive test data from more than a decade of research are compiled on the geotechnical engineering properties of flue gas desulfurization (FGD) sludges with emphasis on double alkali...
