Failures and Problems with Lift-Slab Construction
This chapter provides an overview of failures and problems with lift-slab construction. Topics include jack systems with inadequate take-up devices; the Canadian wedge connection; Serra...

Lifting Collars and Lifting Equipment
The terms lifting collars and shear heads are used interchangeably in the industry. In this book the term lifting collar is used since it is a unique term applicable to lift-slab construction...

The Pentagon Project
The renovation of the Pentagon, now under way, is one of the most ambitious, complex, and challenging construction undertakings in contemporary history. It entails the equivalent of demolishing...

Pressure Tunnels in Fractured Rock: Minimum Cover Criteria from the Stability of Rock Wedges

Design Considerations for Use of Wedge Wire Screens at Surface Water Intake Structures
This paper provides the suggested guidelines for design, construction, operation and maintenance of wedge-shaped wire cylindrical screens used for aquatic biota and trash and debris screening...

Heavy Metal Accumulation in Subsurface, Estuarine Sediments and Inferences for Anthropogenic Enrichment: N.W. Florida Coast
In an attempt to quantify the degree of contamination and the thickness of the contaminated subsurface sedimentary wedge, approximately 100 samples were extracted from the cores and subjected...

Behavior of Thermal Wedges in Oscillating Reservoir Flow: A Case Investigation

Experimental Investigation of Density-Driven Hyperconcentrated Flows
Lock-exchange type of laboratory experiments have been conducted in order to evaluate the dynamical characteristics of density-driven hyperconcentrated fluid mud. Fluid mud, confined in...

Simple Methods for Design of Steel Gusset Plates
This paper presents two simple methods for design of steel gusset plates. In the first method, the wedge theories are applied to establish state of stress in steel gusset plates. In the...

Influence of Surface Finish on Thrust Bearing Life
The original pivoted pad thrust bearing installed and fitted at the Holtwood Power Station in 1912 by A. Kingsbury has been operating continuously since that time without any difficulty....

Gravity-Current in an Open-Channel Flow and Arrested Buoyant Wedge

Generation of Steady Density Currents Through Boundary Layer Control
The paper reports on a study to explore the conditions that trigger bifurcation of ambient flow/intrusion interaction into one of two drastically different regimes, i. e. current versus...

The Rapid Tearing of a Wedge

Effect of Abandoned Roles on Capacity of Wedge Bolts
Seventy, 5/8-in. diameter wedge anchors were tested in direct pull-out to determine the effect of various configurations of unused holes and different treatments of these holes on pull-out...

Field Installation of Concrete Anchorage Systems

Experiments on Arrested Saline Wedge
Experimental results are presented which show that the onset of interfacial wave breaking can be expressed by a stability parameter which is a function of the interfacial densimetric Froude...

Estuarine Front Formation and Propagation
Front conditions associated with estuarine saline wedges are investigated both theoretically and experimentally. It is deduced theoretically that two distinct front types should exist...

Wave Diffraction by Absorbing Wedge
Diffraction of waves by a vertical absorbing wedge is examined. A useful approximate solution, which is in contrast to previous results and is applicable when the two wedge faces have...

Diffraction of Waves by a Wedge
The problem of wave propagation past a vertical wedge has been examined with the intent of generalizing previous solutions and finding useful asymptotic results. Reflection, diffraction,...

Numerical Model of Stratified Estuary Flows
Salt-water intrusion in the Fraser River estuary was modeled numerically and compared with a field measurement program. The salt wedge was observed to have a highly dynamic behavior and...
