Overview of Structural Behavior of Members Subjected to Torsion
The torsion strength of concrete beams depends on many factors, such as the amount of reinforcement, the volumetric ratios of longitudinal and transverse steel bars, the concrete strength,...

Advances in Analytical Modeling of Torsional Members
The basic formula for calculating the torsional strength of reinforced concrete members was developed by Rausch (1929) using the space truss concept. Unfortunately, Rausch's equation may...

Members Subjected to Torsion Combined with Other Actions
The combination of torsion with bending and shear (T-M-V) in members with both transverse and longitudinal reinforcement is the most commonly encountered combination in practical cases....

Detailing and Design Examples for Torsional Members
The nature of the internal force flow in a concrete member subject to torsion brings about both longitudinal and transverse force components. The resulting tension brought about by the...

A New Identity
By repairing and relocating steel trusses, replacing deteriorating approach spans, and replacing what, at the time of its construction, was regarded as a daring concrete truss, engineers...

Outside the Box
Employing an innovative design that made construction quick and economical, the box girder structure carrying Highway N-2 over interstate 80 near Grand Island, Nebraska, became the first...

Case Studies in Steel
An innovative project delivery system for structural steel buildings enables the structural engineer to provide complete structural design services on conventional contractor-led design/build...

Par Excellence
A 50-year-old Brownfield with a mountainous pile of steel slag has been remediate and developed into a recreational site that boasts a free golf course for inner-city youth, a championship-quality...

Evaluation of the CON-ARCH reinforced Concrete Buried Arch System
Final Report
This report summarizes the evaluation of the Con-Arch culvert system marketed by Hunter Contracting, Co. of Tucson, Arizona. The evaluation consisted of computer analysis and field testing of two Con-Arch...

Reconstructed With Precision
Rehabilitating a heavily traveled crossing while traffic continues to flow is a complicated endeavor. Add the attention to detail required to preserve the character of a historic 1920's...

Shell of Steel
To create a saddle-shaped bandstand in a newly developed park in St. Paul, Minnesota, engineers designed a glass-covered, stainless steel lattice grid that makes use of a unique system...

Use of Fiber Reinforced Polymer Composites as Reinforcing Material for Concrete
Although the potential of continuous fiber reinforced polymers (FRPs) was recognized more than 50 years ago, bottlenecks such as vulnerability to static fatigue, ultraviolet radiation,...

Atmospheric Corrosion Resistance of Structural Steels
The main objective of this paper is to provide engineers with data on thickness loss of structural steel members resulting from corrosion. To this end, the writers have collected atmospheric...

Fiber-Reinforced Polymer Composites for Construction—State-of-the-Art Review
A concise state-of-the-art survey of fiber-reinforced polymer (also known as fiber-reinforced plastic) composites for construction applications in civil engineering is presented. The paper...

Work of Art
Cincinnati's new art center is being lauded for its structural animation and innovative use of form. Rendering this sculptural edifice in concrete and steel within a limited...

Island in the Mur
Floating atop an immense pontoon like a shimmering seashell, this elliptical island of steel and glass in the middle of an Austrian river—an inventive, unconventional bridge—was designed...

Advancing Under London
Bored tunnels account for more than 20 percent of the Channel Tunnel Rail Link, the high-speed rail line that will connect the Channel Tunnel with London upon its completion in 2007. In...

An Unconventional Approach
Conceived to resemble a series of covered suspension bridges, Pittsburgh's new $370-million David L. Lawrence Convention Center boasts a cable-supported stainless steel roof...

Can Less Be More?
With its higher strength and improved performance characteristics, high-performance steel is indeed an alluring materials. Its cost, however, also is higher, a factor that cannot be ignored....

Progressive Collapse
This chapter examines progressive collapse. Topics include current practice and integrity steel for loss of support of a lifting collar....
