Retrofitting a Landmark
A decade after it was abandoned, a famous sixty year old tire factory has been rehabilitated as part of a $118 million adaptive mixed-reuse commercial-office mall known as the Citadel....
A Case of the Shakes
New York City's unusual Terrace on the Park offers dining and dancing in a catered ballroom that stands six stories above the ground on four supercolumns. But when guests...
Seismically Safe, Spectator-Friendly
As 50,000 frightened spectators at Candlestick Park can attest, the Loma Prieta earthquake in 1989 provided chilling evidence of the importance of seismic design in public structures....
Peaches and Concrete
One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also...
L'Ambiance Plaza: What Have We Learned
In April 1987, a structure called L'Ambiance Plaza collapsed during construction, killing 28 workers. The building, in Bridgeport, Conn., was being built using the lift-slab...
Engineering a Monument, Evoking a Nightmare
Rather than simply standing as a backdrop for exhibits, the $53.2 million U.S. Holocaust Memorial Museum is intended to be part of the fabric of the exhibition itself. Now under construction...
Real-Time Condition Monitoring of Concrete Structures by Embedded Optical Fibers
Fiber optic sensor methodology has matured to the point where the impact of this new technology is now evident, especially in aeronautics and space structure applications. External perturbations...
Concrete Beam Testing with Optical Fiber Sensors
The use of an embedded multimode optical fiber to monitor curing and load-to-failure testing of a reinforced concrete beam has been investigated. The embedding process used to network...
Condition Monitoring of Structures Using Transient Response
Condition monitoring of structures by measuring transient response and tracking the derived modal parameters has been applied with success in three laboratory studies. Where modal parameters...
Simulated Field Trials of Non-Destructive Concrete Test Methods for Highway Structures
The data presented results from a two year Strategic Highway Research Program investigation into suitable NDT methods for determining the early age, and residual strengths of highway structures....
Review of NPP Concrete Degradation Factors and Assessment Methods
Degradation of concrete in nuclear power plant (NPP) structures can be an age-related phenomena. Several research programs have been initiated by the U.S. Nuclear Regulatory Commission...
Pullout Testing of High-Strength Concrete Members
An experimental investigation of a high-strength concrete mixture was undertaken to measure and evaluate pullout and compressive strength properties. Two columns, a slab, and cylindrical...
VOCs: The New Effluent
The Clean Air Act of 1990, in addition to many state and local regulations, has officials of publicly-owned treatment works (POTWs) shifting their focus, and funds, to air toxic emissions...

Probabilistic Mechanics in Civil Engineering
This paper describes the background, purpose and activities associated with the ASCE Engineering Mechanics Division and its technical committees. This includes research in probabilistic,...
On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...
Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...
