Analysis of steel truss bridges without plans

2019
The bridge load rating provides a basis for determining the safe load carrying capacity of a bridge to ensure the bridge serviceability and safety. In New Jersey, a large number of steel truss bridges, including historical bridges, are currently in service.

Crack Research for Welded Joint of Steel Truss Bridge

Advanced Materials Research, 2011
Steel trusses are often used in the railway bridges.It is known that fatigue cracks may occour in the welded joints under the long-term dynamic loading. If the cracks are not detected and repaired in time, which may endanger the safety of bridges. This paper presents a solid element modeling method by the commercial finite element software package ...

Redundancy Analysis of Steel Truss Girder Bridge

2019
In this paper, the redundancy analysis of simply supported steel truss Girder Bridge has been studied. This paper presents a direct method to determine the redundancy level of the intact bridge using nonlinear analysis. The scope of the study includes checking the redundancy of an intact bridge under the effects of heavy loads as well as evaluating ...

Design of Prestressing Tendons for Strengthening Steel Truss Bridges

Journal of Bridge Engineering, 2008
The paper introduces a design space for the design of prestressing tendons concentric with members for strengthening steel truss bridges. The design space contains all feasible solutions for the cross-sectional area of the tendon and the level of prestressing that satisfy the following criteria: (1) tendon yielding; (2) member buckling; and (3) member ...

Inspection and Rehabilitation of Steel Trusses for Highway Bridges

1990
Steel trusses played an important role in the development of highway transportation in the United States between 1870 and 1940. In this period of time, numerous patented structural steel (and wrought iron) structures were designed and constructed by engineers/contractors on major state highways and rural county roads. Many of these structures have been

Full scale testing of old steel truss bridge

Journal of Constructional Steel Research, 2002
Abstract As part of an investigation to comprehend behavior of old steel truss bridges, ultimate load tests were carried out on a steel truss bridge that was transported to the structural laboratory. The first ultimate load test consisted of testing the bridge in its existing configuration without any retrofit.
