Touchdown for O-Cell Test
The Los Angeles Memorial Coliseum was badly damaged by the Northridge earthquake. There was seven months to complete 3 years of work to be ready in time for football season. The project...
The Northridge Fractures: Are We Learning the Right Lessons?
After the Northridge earthquake in January 1994, engineers found problems with special moment-resisting frames. There were multiple facture modes, and typical damage involved primary crack...
Guidelines for Evaluating Aging Penstocks
Lessons From Kobe
On Jan. 17, Kobe, Japan became the first post-World War II, heavily populated, industrialized area to bear the full brunt of a high-magnitude earthquake. Engineers hope the resulting destruction...
Northridge Postscript: Lesson on Steel Connections
Immediately after the Northridge earthquake in January 1994, the general concensus was that steel-framed buildings performed extremely well. Later, inspectors were surprised to find weld...
In the Wet
The concept of using large diameter vertical cylinder piles of steel and concrete is not new. Vertical cylinders constructed in pneumatic caissons go back at least 70 years. Steel cylinders...
NDE for Steel Bridges
Nondestructive evaluation (NDE) is the only way to detect fatigue cracks hidden by the paint on steel bridges, and FHWA-sponsored research into the problem has been given highest priority....
Composite Sketch
Composite materials from the aerospace and military sectors are showing promise in highway, bridge and transportation applications. Some of the current and potential applications of composites...
Engineering a Landslide
A slope failure in northwest Alabama has been stabilized using a system of grouted INSERT piles to provide load transfer across the failure surface of the slide. This system, referred...
Advances in Underground Pipeline Engineering II
The first international conference on Advances in Underground Pipeline Engineering was held in 1985. Some 50 authors and over 300 delegates from 20 countries took part in the presentations...
Designing for Drama
Near the Passaic River in Newark, N.J., not far from the famous Iron Bound restaurant district and Newark's Penn Station, construction crews swarm around the steel skeleton...

A Primer on Micropiles
A major study of micropile technology has recently been funded by the Federal Highway Authority and completed by the authors. The subject is defined as a drilled and grouted, cast-in-place,...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
Real-Time Control for a Robotic Rebar Bender
Job conditions and variability in the properties of the stock material combine in a rebar bending operation to create a challenging environment for a robotic bender. This paper reports...
Analysis of Inflating Habitable Space Structures with neomass (near-Earth-object mass)
The discovery of near Earth objects (NEOs), during August 1992, and that one of them is a dormant comet, dramatically changed the potential availability of near-Earth resources. NEOs provide...
Biosphere II - Its Effects on Space Colonization
In the middle of the Arizona desert, a strange sight can be seen. A small world with ecosystems and different climate zones, just like Earth, is enclosed in glass and steel. The 3.15 acre...
