The Basics of Water-Resistant Brick Walls
Water-resistant masonry walls of burned clay or shale brick are the result of a conscious effort to produce them, by everyone involved in their creation. Furthermore, owner maintenance...
Rehabbing Research
Because a growing share of Corps of Engineers' effort is going int rehabilitation, likewise a growing share of its research is too. This shift in emphasis is encouraged by...
Soil Nailing a Wall
Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting...
Complexity in Concrete
Centrust Tower in Miami, Fla., is a $95 million, 37 story, 600,000 sq ft tower rising from one side of a block-square 11 story parking garage. Columns on the curved side of the triangular...
Ice Forces Due to Impact Loading on a Sloping Structure
Two approximate methods are presented for determining Dynamic Magnification Factors due to floe impact on sloping structures. Some of the physical processes involved are treated simplistically,...
Ice Loads on Structures With Compound Slopes
Many of the offshore drilling structures proposed for use in the Arctic have sides with multiple slopes. Sloping walls are used at the waterline to cause the ice sheet to fail in bending...
Look Back and Learn
The cancellations of some nuclear power plants are being attributed in part to cost overruns due to construction-related problems. The experienced civil construction engineer involved...
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
Hydraulic Fracturing in Embankment Dams
There is now sufficient evidence to conclude that concentrated leaks occur commonly through the impervious sections of embankment dams by hydraulic fracturing without being observed, even...
The Use and Performance of Seepage Reduction Measures
The utilization and performance of various foundation seepage reduction measures from over 100 dams situated on pervious soils throughout the world has been reviewed. Summary discussions...
Design of Framed Steel Structures with Infill Reinforced Concrete Walls
It is a well-known fact that an infill shear wall in a frame acts as a compressive diagonal strut, giving strength and inflexibility to the frame. Recently the Architectural Institute...
Monitoring Saves a Site
A comparison is made of two supported excavations that were similarly designed and constructed. Both excavation support systems consisted of a soldier pile and lagging sheeting wall supported...
Optimization of Variable Volume Diaphragm Filter Presses
The St. Paul, MN, Metropolitan Waste Control Commission Wastewater Treatment Plant has installed and operated eight variable volume diaphragm filter presses for four years. During this...
Foreshore Treatment as a Method of Coastal Protection
This paper describes the damages sustained by a small section of the Vancouver, British Columbia coastline during the passage of a storm in December, 1982. This stretch of protected coastline...
Erosion Control Measures for Shoreline Property
Numerous Federal acts relating to beach erosion and shoreline protection have been enacted impacting Hawaii's ocean and shoreline. In an effort to protect the shoreline, many...
Myrtle Beach, S.C. A Shorefront Management Plan
