Repeat Performance
Working with a budget of $10 million, engineers designing a new high-rise residential structure in New York City had to find creative ways to control costs. One budget-saving idea was...
Quality Control Test for Prestressing Wires in Concrete Pressure Pipe
Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts...
Making the Most of HPC
Developing high-performance concrete (HPC) was only the first step toward bringing a material with improved durability, strength, constructability, and mechanical properties to the bridge...
Ancient Concept, Modern Context
For several centuries, Bibliotheca Alexandrina was the cultural center of the Western world. It was built by the heirs of Alexander the Great some 2,400 years ago and burned, some say...
Modeling of Inelastic Behavior of RC Structures under Seismic Loads
Proceedings of the U.S.?Japan Seminar on Post-Peak Behavior of Reinforced Concrete Structures Subjected to Seismic Loads: Recent Advances and Challenges on Analysis and Design, held in...
Stronger Longer
Like many older concrete bridges, the Sierrita de la Cruz Creek Bridge, a 1957 crossing near Amarillo, Texas, suffered from concrete deterioration. When the Texas Department of Transportation...
The Many Faces of RCC
The Chinese government, under an aggressive move to boost its hydroelectric power output, is building an extensive system of dams nationwide. Chinese engineers have developed innovative...
Magnetic Perturbation Imaging for Prestressed Concrete Evaluation
Many prestressed concrete bridge structures in the United States and other parts of the world are over thirty years old and have shown various signs of distress. Corrosion or fracture...
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...
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...
Rehabilitation of the Packers Falls Bridge
The Packers Falls Bridge was constructed in 1912 and consists of a 42' (12.8m) single span, reinforced concrete arch structure. This bridge was constructed using a unique forming system...
Evolution of Composite Floor Systems in the United States
Composite floor systems, which combine structural steel beams with a cast-in-place concrete slab, have grown in popularity in the U.S. during the past 40 years. In most early applications,...
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,...
Long-Term Performance Program
Making Something of It: Papers from the International Contest on LTPP Data Analysis 1998-1999
Sponsored by the Highway Division of ASCE; Long-Term Performance Program of the Federal Highway Administration. This collection contains papers from...
Turning with the Wind
A 125-m high tower built at the site of the Glasgow Science Center in the United Kingdom required some innovative design methods. To reduce the aerodynamic effects imposed on the slender...
Holding Steady
The San Diego�Coronado Bay Bridge is an unmistakable landmark that frames the skyline of downtown San Diego, providing a vital link between the mainland and the Coronado peninsula. The...
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...
Extended Life Span
The Harlem River Lift Span�part of New York City's Triborough Bridge System�was the largest vertical span in the country at the time of its construction in 1936. The lift...
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...
