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...
Box Girder Balancing Act
On November 18, 1999, cranes lowered into place the last of 202 precast concrete segments that form the main span of the new Sagadahoc Bridge, a $46.6 million crossing that boasts the...
State of the Arts
The complicated structural engineering that went into the Nancy Lee and Perry R. Bass Performance Hall in Fort Worth, Texas, allows patrons and performers to focus fully on the arts, and...
Talmadge Bridge Replacement
This paper discusses the design of the main spans and approach spans for the replacement of the Talmadge Bridge for the Georgia Department of Transportation. The design of the concrete...
Monitoring Stay Cable Forces During Construction of the Natchez Trace Parkway Arch Bridge
This paper describes how cable-stay forces were indirectly quantified through the use of simple field measurements. A system was developed and delivered to the contractor and used to make...
The Normandie Bridge
The Normandie Bridge will have one of the longest cable-stayed spans in the world, i.e. 856 m long. This paper briefly describes the design of the bridge, with the concrete access spans...
Design of Frames Using Notional Horizontal Force
The cantilever columns and portal frames are studied by using the notional horizontal force design concept. This concept intends to eliminate K-factor in the frame design. It was found...
Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....
Superlong Cable-Stayed Bridges
Superlong cable-stayed bridge span is defined as one over 1000 meters. Problems requiring special attention regarding these bridges are discussed, namely: excessive cable sag; high axial...
Ambient Vibration Response of a Long Span Bridge
Natural frequencies, mode shapes and damping characteristics for a long-span cable-stayed bridge were experimentally determined from a series of ambient vibration tests for both the cantilever...
Time-Dependent Analysis of Nonprismatic Curved PC Box Girder Bridges
The purpose of this paper is to present a step-by-step computer method for predicting the deflection and stress distribution duo to creep and shrinkage of concrete in nonprismatic, curved,...
Concrete Arch Bridges Using Composite Techniques
Use of composite structure is an advantageous method to construct concrete arch bridges. This paper reports two successful examples of concrete arch bridges of composite construction using...
A Second Order Analysis Technique for Nonprismatic Bridge Piers
An approximate second order method is presented for the analysis and design of cantilever compression members. Prismatic members with nonconstant reinforcement, and nonprismatic members...
Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...
Vibrations of Linearly Tapered Cantilever Beams
Originally published in: Journal of the Engineering Mechanics Division, ASCE, EM2, April 1962, pp. 95-123...
Analysis of Tapered and Stepped Columns by Analogy to Cantilever Deflection
An analysis is developed for handling the buckling design of tapered and stepped columns with the aid of the so called 'amplification factors'. When these factors...
Analysis of the Non-Planar Response of a Cantilever, with the Aid of Computerized Symbolic Manipulation
The nonlinear differential equations governing the static deformations of a cantilever with a tip mass are formulated and analyzed with the aid of computerized symbolic manipulation. The...
Analysis and Design of Wind- and Earthquake-Resistance of an S-Curved Cable-Stayed Bridge
Just recently, in January of 1987, the first S-curved cable-stayed bridge in the world has been completed as a part of Metropolitan Expressway's Katsushika-Edogawa Route in...
Vancouver's Skytrain Cable-Stayed Bridge?Dynamic Behaviour
This paper focuses on the dynamic behaviour of the Skytrain cable-stayed bridge under the action of earthquakes and wind. The 340 m span railway bridge is located on the west coast of...
Sunshine Skyway Ship Collision Criteria
The 'new' crossing of Sunshine Skyway was born, not only to replace the previous crossings and improve the regional economy but also with increased clearances...
