Bibliography of Steel Columns
This book, which was prepared by the Committee on Compression Members of the Structural Division of the American Society of Civil Engineers, attempts to provide a complete bibliography...
Rehabilitating West Point's Tunnel
Conrail, the Northeast's largest freight railway, had a problem with a tunnel carrying the fastest freight line between the New York area and the Pacific. The 1882 tunnel...
Building Blocks for the Future
In the near term, advanced, conventional materials�namely higher-strength steel and concrete�will dominate infrastructure rehab. New steels of higher strengths and toughness are increasingly...
Cleaning Up: The Second Decade
Endless media coverage and a high level of public anxiety make it seem as though the U.S. has been attempting to clean toxic waste sites for decades. In fact, the 1980s were our first...
A Possible Paradigm
`We work only on a lump sum basis, with work guaranteed on time, and no extras. We help you define the scope of work, using our experience and unmatched computerized databases, then guarantee...
Remediation Technologies in Use for Groundwater and Soil Contamination in the Santa Clara Valley
Silicon Valley is known as the origin and the heart of the high technology (Hitech) industry. However, tech-nologies used for soils and groundwater remediation in the valley are not necessarily...
Leveling the Playing Field
As professional sports grow, so does the market for elaborate multi-use sports arenas. The new Target Center in Minneapolis features a unique movable floor, 68 luxury suites and a state-of-the-art...
Building Moon Bases
It is widely accepted that the U.S. will begin to build a base on the moon at the turn of the century, and much of the design work has already been done. Based on papers presented at Space...
Diatomaceous Soils: A New Approach
Diatomaceous soils are formed over long periods of time when the skeletal remains of plankton and other single-celled marine creatures sink and accumulate in lakes, estuaries and oceans....
High Tech on Campus
Hannan Hall, the new laboratory building at The Catholic University of America, has a structure entirely made up of precast concrete panels and 24 in. deep double tees. The loadbearing...
Repair and Rehabilitation of Damaged Steel Flexural Members
In earlier years, the primary method for repairing steel flexural members was to replace the member. However, with the cost of labor and material increasing dramatically over the last...
Local Buckling Behavior of Plate Elements
In the elastic post-local buckling range, the stress distribution across the width of compression elements of light gauge steel shapes is nonlinear. For code implementations, these stress...
Strength of Biaxially Crooked Jumbo Columns
The ultimate strength of axially loaded jumbo columns with biaxial initial out-of-straightnesses is analyzed by the finite element method. The analysis makes use of the measured residual...
Analysis of the Non-Planar Response of a Cantilever, with the Aid of Computerized Symbolic Manipulation
The nonlinear differential equations governing the static deformations of a cantilever with a tip mass are formulated and analyzed with the aid of computerized symbolic manipulation. The...
High Strength Concrete: Proportioning, Behavior and Applications
Generally, concrete with a cylinder compressive strength higher than 6000 psi (41.4 MPa) is designated as high strength concrete. High strengths are achieved using stronger coarse aggregates,...
Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Freezing and Thawing Durability of High Strength Silica Fume Concrete
Specimens from 27 batches of concrete with a water to cementitious (cement plus silica fume) ratio of 0.25 to 0.32, with and without entrained air, were tested for freeze-thaw durability...
Surface Treatments for Concrete
The US Army Corps of Engineers initiated in 1984 a research program designated Repair, Evaluation, Maintenance, and Rehabilitation (REMR), one of the work units being the evaluation of...
High Molecular Weight Methacrylate for Sealing Cracked Concrete
The sealing of cracks in concrete surfaces has been one of the most difficult types of repair to accomplish. Epoxy injection has been widely used, but due to its relatively high cost,...
