A state-of-the-art training facility at a Texas community college is ready to train fire and rescue personnel to cope with disasters ranging from fuel fires and floods to collapsing structures...
Saving Saluda
One of the largest roller-compacted-concrete berms in the United States will stand sentinel in case South Carolina's Saluda Dam undergoes liquifaction in response to strong...
Using Tracer Response Curves to Quantify Hydraulic and Channel Complexity of Prairie Creek, Northwestern California: Implications for Over Wintering Habitat for Juvenile Coho Salmon
This study measured and compared aspects of channel structural complexity with hydraulic complexity at a range of flows including winter storm flows. Five 200-meter reaches containing...
A Grand New Bridge
Approximately 65 km south of Seoul, rising above the Asan Bay, the Seohae Grand Bridge now stands as the longest bridge in South Korea. The 9.4 km long cable-stayed bridge, which runs...
Effect of Column-to-Beam Strength Ratio on Seismic Performance of RC Moment Frames
Reinforced concrete (RC) moment frames are often used in building applications. During strong earthquake excitations, such buildings have been subject to soft-story or column sidesway...
The Effect of the Slab on Beam-Column Joint Behavior
The three-dimensional effect of slab interaction on frame behavior has been observed in lateral load tests on beam-column-slab elements....
New Concepts in Structural Strength Assessment for Large Buildings in Fire
This paper presents theoretical descriptions of the key phenomena that govern the behaviour of composite framed structures in fire. These descriptions have been developed in parallel with...
New Developments in the Field of Seismic Isolation
This paper will concentrate onwhat likely, is the most significant of these issues: changes in the mechanical properties ofseismic isolation and energy dissipation hardware as they are...
High-Tech Inspection
The Federal Highway Administration's National Bridge Inspection Program requires the states to report the condition of its bridges as determined by visual inspection, and...
Going Against the Grain
Conventional wisdom has it that granular soils perform better in mechanically stabilized earth (MSE) wall systems. Their properties are well known and simple to express in mathematical...
Dynamic Response of Lattice Towers and Guyed Masts
Prepared by the Task Committee on the Dynamic Response of Lattice Towers of the Technical Committee on Special Structures and the Technical Administrative Committee on Metals of the Structural...
Wind Load Provisions
This chapter explores the provisions of the Wind Load standard....
Examples
This chapter contains ten examples of determination of wind loads using the analytical procedure of the ASCE 7-98 standard....
Space Truss
The International Space Station will be more than 310 ft (94 m) long when it is completed sometime in the next decade. The backbone of the structure is a hexagonal truss system that will...
Design of Structure and Damping System to Control Motions of the Park Tower, Chicago
Park Tower, a 67 story condominium/hotel project currently under construction on the Magnificent Mile, Chicago, IL, will be the first building in North America in recent times that utilizes...
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...
Digging for Answers (Available in Geoenvironmental Engineering Special Issue only)
Research at the six facilities that make up the National Geotechnical Experimentation Sites (NGES) has included tests on minipiles, groups of driven piles, shafts drilled in rock, and...
Testing the Load (Available in Geoenvironmental Engineering Special Issue only)
The Pittsburgh District of the U.S. Army Corps of Engineers recently began construction of a new gated dam to replace a nearly 100-year-old concrete fixed-crest dam on the Monongahela...
Wireless Warnings
Formwork failures cause dozens of construction-related deaths per year, but most can be avoided by adequate monitoring. The problem is, most monitors must be hard-wired to a computer on...
Taking a New Approach (available in Structural Engineering Special Section only)
The first bridge rehabilitation project in Washington, DC to use the AASHTO Load and Resistant Factor Design (LRFD) specification reveals several lessons to be learned from using the newly...
