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...

Bell's Bridge Rehabilitation
Bell's Bridge carries Tidewater Drive, a major urban arterial in the City of Norfolk, Virginia, over Wayne Creek, a tributary of the Lafayette River. During a routine inspection in 1995,...

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...
