Tall Order
Successive earthquakes have damaged the 32-story, 460 ft (140 m) tall Los Angeles City Hall, built in 1926. Masonry infill and concrete walls have cracked, and the terra cotta cladding...
Evaluation of the SSL MSE PlusTM Retaining Wall System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF service center. This report describes a HITEC evaluation designed to...
Ground Attack
Buried surfaces made of concrete, ductile iron and carbon steel are susceptible to corrosion by the soil that surrounds them, but there are numerous ways that these surfaces may be protected....
Muscle Made of Carbon Fiber
Carbon fiber reinforced plastic (CFRP) extends service life and increases load-bearing capacity when applied to concrete structures. CFRP is less expensive than traditional strengthening...
Repeated Loading of Stabilized Recycled Aggregate Base Course
The fatigue behavior, resilient properties, and progressive accumulation of damage due to repeated flexural loads on a fiber-reinforced pavement base course material composed of cement-stabilized...
Do Coated Pipes Last Longer?
Field studies have revealed that polymer coated steel pipe resists corrosion longer than pipe coated with other materials. Corrosion is the most common failure mechanism of pipe culvert,...
Bridge Within a Bridge
A multinational consortium retrofitted the Tagus River suspension bridge in Lisbon, Portugal. The retrofit included widening the roadway deck from five to six lanes, installing a railroad...
Superfund Success, Superfast
After 15 years of indecision, unprecedented cooperation among regulatory agencies, community action groups, and Potentially Responsible Parties (PRPs) resulted in the completion of remedial...
A Race to Innovate
The annual Concrete Canoe Competition, which is co-sponsored by the ASCE and Cleveland-based Master Builders, fosters several engineering breakthroughs that are ignored or forgotten by...
Better Salt Storage
Facing tighter maintenance budgets and stringent environmental regulations, many highway departments are designing and building innovative structures to store road salt. One such structure...

Comparison of Blast and Earthquake Effects on Reinforced Concrete Frame Structures
This chapter compares the damage done by an explosive blast and an earthquake....
Catching Up on Composites
Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials...
Boston's Third Harbor Tunnel (Available only in
Boston's immersed marine tube, the Third Harbor Tunnel, connecting South Boston and Logan Airport, is a $226 million component of the multi-billion dollar Central Artery/Third...
Recover Inorganic Solids from Obsolete Propellants
A feasible process was developed to recover inorganic solids (energetics and metallic fuel) from obsolete polyurethane-based propellants in order to solve their associated long-term disposal...
