This in turn affects reliability. Construction of this kind of bridge is based on smart use of compression and tension. Truss bridges utilise a number of shapes and are built using different materials. The objective of this study is to evaluate the potential benefit of secondary elements on the system reliability of girder bridges, if these elements are designed with the structural system to participate resisting vehicular live loads. This is because the vertical members are in compression. However, low structures may be founded on alluvial foundations provided with adequate cutoffs. The truss utilizes Newton’s laws of motion especially statics that forms an important part of the laws. Trusses are capable of supporting considerable external loads over a large span and use a relatively small amount of material, … Built 1909 by the Kansas City Bridge Co.; made obsolete by new bridge 2008, but remains open to traffic. Truss bridge is very strong because they are completed of triangles that are ridged. This is why they are also known as braced wall lines in some region. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by nineteenth and early twentieth century engineers. The traditional design of a bridge incorporates arches because of the amount of strength this design offers. A truss is used because it’s a very rigid structure that transfers the load from a single point on a bridge to a much wider area. Pratt Truss Bridge. Twenty six predate 1888 and represent the era of experimentation that evolved into standardized designs by about 1888. Walls must be connected to the roof because walls and roofs can strengthen each other if connected properly (Zhou, 2008). A truss bridge requires high levels of ongoing maintenance.

The options make the truss bridge both versatile and economical to build. An arch bridge can only be of a certain size, so it is either multiple arches are needed for the foundation of the structure or other reinforcement materials should be included to support the loads it will face. Economy: Though bridges, as a rule, do not earn much by way of toll taxes, they nevertheless can help decide whether to invest in a particular city or not. I read up on it: A K-Truss is usually used for reinforcing members with high axial compression, not so much for bending; this is because the diagonals take almost nothing of the axial force. Structural engineering can be defined as the design of structural support systems for buildings and other structures. Camelback Truss in Oklahoma Historcal Camelback Bridges Pros and Cons to the Camelback Truss Design Camelback Truss History advantages Scale Design less material able to span long distances without sacrificing strength evenly distributes tension and compression throughout the. The iron could be transported to the building site where it would be assembled with only semiskilled labor. The advantages of truss bridges is that it is economical, light, strong and uses short timbers. In trusses, this transfers the entire weight of the roof to the outer walls, and has the advantage of allowing the interior walls to be built arbitrarily, or even moved or omitted.
