Strengthening and widening of steel pony truss bridges

Canadian Journal of Civil Engineering, 1977
There are many thousands of existing pony truss bridges in North America which were constructed in the earlier part of this century and are still serving as important traffic carriers. The present economic situation demands that these bridges should usefully serve their purpose for as long as is safely possible.These bridges could be found inadequate ...

Truss Bridge Rehabilitation Using Steel Arches

Journal of Structural Engineering, 1984
There are many bridges in North America that are inadequate for modern traffic loads because of deterioration or insufficient original design strength, or both. Although many of these bridges do not meet the present standards for roadway width and other geometrical considerations, they are serving well, probably because of low traffic volumes on these ...

Sunkou Steel Truss Railway Bridge, China

Structural Engineering International, 1997
The 2381 km long Beijing-Kowloon Railway Line, opened for traffic in September 1996, is the one of the largest civil engineering projects in China in recent years. It extends from Beijing to Shenzhen, where it connects with the Kowloon Railway Line to Hong Kong.

Rehabilitation of Tornionjoki Steel Truss Bridge, Finland

Structural Engineering International, 2002
An old steel truss bridge located in North Finland was rehabilitated by replacing the old wooden deck with a steel orthotropic deck. The deck was prefabricated in the workshop and installed in its final position by the launching method. All structures and joints of the steel deck are simple and accessible to avoid corrosion problems in the future.

Dynamic Performance Analysis of Steel Truss Bridge

Applied Mechanics and Materials, 2013
Steel truss bridge is an important part of transportation hub and lifeline engineering, it recently has attracted more attention on dynamic performance of steel truss bridge. In this paper, the ANSYS software is used to perform the modal analysis of steel truss bridge, and we find that the main bridge are more sensitive to the vertical earthquake (i.e.,

Structural Health Indices for Steel Truss Bridges

2011
Steel bridges represent a significant portion of the nation’s aging bridge inventory. The United States Army’s inventory has over two hundred steel bridges that are vital to the operation of nearly every Army Installation. The Army regularly inspects their bridges to ensure the continued functionality of the bridges.

Behaviour and evaluation of pin-connected steel truss bridges

Canadian Journal of Civil Engineering, 1987
Two posted bridges, with pin-connected steel trusses, were recently proof tested in Ontario. This paper presents some results of the tests and draws conclusions, which are also applicable to other similar structures. It is concluded that, unlike other bridge types, this type of bridge does not possess reserve strengths beyond those ascertained ...

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 ...
