High Performance Dampers for Bridges
A multi-disciplinary research study investigates the use of shape memory alloys as seismic dampers in bridges. Shape memory alloys are a class of alloys that display several unique characteristics,...
Cyclic Behavior of Three-Dimensional Partially-Restrained Composite Connections
This paper describes the test of a full-scale, bi-directional, PR composite beam-to-column connection. The PR connection consisted of continuous reinforcement bars across the column and...
Under the Microscope
Forensic engineering is typically more complex than engineering design because it requires the integration of specialized knowledge of materials science, structural analysis and design,...

Terminal Island Turnaround
The Pier T marine terminal at the Port of Long Beach is a new 375-acre (152 ha) container terminal being developed at the former Long Beach Naval Station and Naval Shipyard. The $525-million...
Concrete Delivers
The latest addition to the skyline of Shanghai, China, is a strikingly slender all-concrete 62-story office tower. It is the city's tallest all-concrete building, achieving...
Composites Enhance Timber Bridges
Two relatively new technologies are available for reinforcing or strengthening timber bridges with fiber-reinforced polymers (FRPs). The first consists in reinforcing the tension side...
Dual Benefits
When the Port of Houston needed to be dredged to accommodate larger commercial vessels, engineers decided to put the dredged material to use to create wetlands and islands that will serve...
The Road to Reuse
Many types of wastes and by-products have potential uses in the highway environment. Applications for recycled materials include asphalt pavement, portland cement concrete pavement, granular...
Liner Lessons
The County Sanitation Districts of Los Angeles County comprise 25 independent special districts that cover a service area of approximately 770 sq mi (1,990 km�). Since the early 1990s...
Bridge to the Future
An arched footbridge under construction in Seoul, South Korea, that is reconnecting the metropolis with a tranquil island, will demonstrate the compressive strength and sleek design potential...
Megaproject Management
By the dredging and landfill project manager for the Port of Los Angeles and Alan E. Alcorn, P.E., an associate vice president of Moffat and Nichol Engineers in Los Angeles. The Pier 400...
New Navigation Channel
Among the facilities needed to accommodate Pier 400 at the Port of Los Angeles (POLA) was a new navigation channel to handle the increased container and liquid bulk traffic that the port...
Twenty-First Century Terminal
The Port of Los Angeles is already the busiest container facility in the United States, and the eighth busiest in the world. In 2000 it handled some 112 million tons (102 million Mg) of...
Gap Analysis for Durability of Fiber Reinforced Polymer Composite in Civil Infrastructure
Prepared by the Civil Engineering Research Foundation. This report provides the results of a study on what is known and not known about the use of...
Moving Mountains
The earthmoving and rock-crushing operations at the Eastside Reservoir represented one of the largest such projects in the history of the United States. The earth and rock-fill dams required...
Experimental Approach
One of the best kept secrets during World War II, the K-25 facility in the Cumberland Mountains of East Tennessee prepared uranium for use in nuclear weapons. By 1987, the 13 million sq...
On Martian Soil
Discussions are ongoing about how and when to build human settlements on other worlds. Many scientific discussions have focused on settlements on Mars, and how the initial colonists would...
Road Test
The National Center for Asphalt Technology at Auburn University is building a $7 million, 1.8 mi (2.9 km) oval test track to perform accelerated pavement loading experiments. At least...
On the Cutting Edge
Smart materials, innovative monitoring systems and sensors, exotic tunnel-boring machines, and self-sustaining treatment systems are among the latest technology advancements that are helping...
