Shore Protection Design—A Necessary Evil
Since much shore protection exists and further shore protection will be considered necessary in the future, this paper addresses the need for better design methods to replace the present...

A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...

Seismic Response of Composite Coupled Walls
In many structures, height restrictions may require coupling of reinforced concrete walls by structural steel beams rather than conventional reinforced concrete beams. Through an experimental...

Bending of Retrofitted Test Foundation Walls
New repair methodology has been developed for residential construction that can be used to retrofit foundation bearing walls damaged by mine subsidence. The repair strengthens the foundation...

Thin Walled Circular Concrete Filled Steel Tubular Columns
The thin walled steel tube filled with high strength concrete delivers the economies of a concrete column with the speed of construction and the constructability of a steel column resulting...

Steel Panel Encased R.C. Composite Shear Walls
In order to make clear the fundamental resisting mechanisms of composite shear walls, tests are carried out on the composite unit rigid frames with various infilled shear walls. Composite...

The Pipe/Soil Stiffness Ratio Variable
This paper reviews the factors which affect the reactions and defines performance limitations of buried flexible plastic pipe as a function of load-induced strains and deflections. The...

Generic Problems
Generic Problems are basic problems in structural mechanics that recur frequently, have been investigated experimentally and involve the behavior of elements or components found in many...

Seismic Design of Multi-Story, Wood-Framed Buildings
The seismic design and analysis of wood-framed structures is relatively simple; however, the challenges that present themselves within this design medium are shear and overturning force...

The Copper-Clad Library
The design vocabulary for the new Phoenix Central Library includes saddlebags, power bellies, tensegrity and corrugated siding. The saddlebags are copper-clad, steel-framed core structures...

Can Engineers Cut Curtain-Wall Failures?
For many reasons, including owners' false perception of economy engineers have abdicated responsibility for curtainwall design. Failures of curtainwall components are very...

Ups and Downs in Chicago
The Chicago Title and Trust Center—a 50-story mixed-use complex which opened late last year—offers 1.3 million sq ft of above-grade space, and three levels of below-grade parking. The...

The Crown and the Curtain Wall
Crowning the complex curtainwall of an 870 ft concrete tower with a 150 ft high crown of aluminum masts in concentric rings above the 60th floor required ingenuity and extraordinary cooperation...

Overhead and Profit on Change Orders
Have you ever wondered how many change orders it took to build the Egyptian pyramids or the Great Wall of China? The concepts of overhead, profit, and change orders have been around for...

Backfill-Stiffened Foundation Wall Construction

Gabions and Geogrids
The century-old gabion concept can be improved upon by adding geogrid reinforcement to the soil embankments the gabion wall is designed to support. The grids add stability to the embankment...

Design Loads for Sloshing in TLP Pontoons Tanks
Impact of fluid inside the Auger TLP ballast tanks on tank walls was investigated and changes made to the structural design in an accelerated fashion through the use of model testing....

The Design and Construction of Shuikou Project RCC Diversion Wall
Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101...
