Actual Versus Assumed Behaviour of Girder Bridges
It is generally believed that the discrepancies between calculated and actual responses of bridges can diminish, to the point of being nonexistent, with refinement in the method of analysis....

Reliability of Cracked, Prestressed Girders
For prestressed concrete structures in non-aggressive environments or where corrosion-protected prestressing strands are used, it may be possible to allow flexural cracking into the precompressed...

Variability Analysis of Bridge Responses Using the Semi-Continuum Method
The semi-continuum method is used for Monte Carlo simulation of a large number of bridges. It is confirmed that the mean values of responses can be obtained deterministically, and their...

Applying the Time-Reliability Equation
This paper presents a methodology for rigorously including time-varying elements of reliability through the use of the time-reliability equation. An example reliability analysis which...

Fatigue Reliability of Ship Hull Girder
Based on estimates on uncertainties in wave loading and fatigue capacity the fatigue reliability of ship hull girder is calculated with respect to global vertical wave bending moment....

Swiss Cheese Box Girders
Now going up in the French Alps, the Sylans and Glacieres viaducts have decks supported by three-dimensional arrays of concrete trusses. The superstructures look like concrete box girders...

Corrosion Damage Models for Steel Girder Bridges

Design of a Post Tensioned Segmental Swing Bridge

Steel Plate Girder Alternate I-10/I-17 Interchange
The scope of the Phoenix I-10 Viaduct allowed extensive study for the optimization of this moderate span steel plate girder bridge. The value engineering studies lead to the use of the...

Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...

Structural Systems for Multispan Cable Suspended Bridges
Multispan cable suspended bridges, i. e. , cable-stayed or suspension bridges with a large number of consecutive main spans of equal size, must be carefully designed to become economical...

Development of a Double Tee Structural System for Highway Bridges
The fully precast, prestressed double tee beams are tied together by transverse post-tensioning through simple grout filled V-joints. The system provides for complete transversal continuity...

Prediction and Control of the Wind Response of Long-Span Bridges with Plate Girder Decks
The aerodynamic stability of plate girder decks and methods of improving it are discussed. The selection of an appropriate design wind speed for flutter is reviewed including the effect...

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...

Wind Buffeting of Long Span Bridges with Reference to Erection Phase Behaviour
The balanced cantilever technique for cable-stayed bridge erection can lead to an unacceptable buffeting response at high wind speeds unless the erection scheme is carefully studied. The...

Safety of Long Span Highway Bridges Based on Dynamic Response
This paper consists of an analytical study regarding the dynamic response of highway bridges subjected to heavy vehicle loads, with emphasis on long span low fundamental frequency bridges....
