COMPARISON BETWEEN BAILEYS BRIDGE TRUSS AND SUSPENSION BRIDGES Name Institution Comparison between Baileys Bridge Truss and Suspension Bridges The Bailey bridge trusses are bridges that are portable and comprise of pre-fabricated trusses (Katohi‚ 2013). They were designed to assist the military to cross wide cliffs and gaps of up to 200 feet (Caney‚ 2006; McGloin‚ 2008). In the contemporary world‚ longer Bailey bridges have been constructed‚ and are able to function effectively to allow smooth transportation

Effects of wind-loading on bridges Wind Loading Wind is a word that used to describe the motion of the air. It is the natural phenomenon which caused by temperature differential that is resulted from solar radiation. A moving wind that comes in contact with a solid structure will be distracted. Although the wind structure is not fully stopped‚ it still loses some of its velocity. This is due to the frictional force faced by the wind flow and the surface of the bridge. This phenomenon is actually

Truss Analysis Introduction This report is writing about using the ANSYS 14.5 to help optimize the structure. To construct a structure in ANSYS‚ the most important thing is to define the node locations and the relations between nodes and elements. Each node‚ element‚ and cross-section area has to be matched up. All the data need to be entered in a text file. After the structure has been built‚ all the displacements on nodes and stress on the elements have to be solved. Use solutions

is a truss‚ which is a structure of associated components that shape triangular units. In the late nineteenth century and early twentieth century‚ more than half of the bridges that were made‚ were made out of stone. But since the United States had so much wood‚ they made a lot of wooden bridges in those times and a vast majority of them were truss bridges. As the years passed on‚ the real iron and steel organizations are gone‚ truss bridges stay as their legacy. One of the most famous truss bridges

n architecture‚ a truss is a structure comprising one or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes. External forces and reactions to those forces are considered to act only at the nodes and result in forces in the members which are either tensile or compressive forces. Moments (torques) are explicitly excluded because‚ and only because‚ all the joints in a truss are treated as revolutes. A planar truss is one where all the members

Name and describe the 3 most common types of bridge truss types: Warren: The Warren Truss uses equilateral triangles to spread out the loads. The triangles reduce the forces to only compression and tension. Pratt: A Pratt truss includes vertical members and diagonals that slope down to the center. The inner diagonals are under

figured out the best way to built it we would test it ourselves. The Pratt truss was first developed in 1844 under patent of Thomas and Caleb Pratt. Since the 1840s through the early twentieth century‚ the Pratt has diagonals in tension‚ verticals in compression‚ except for the hip verticals immediately adjacent to the inclined end posts of the bridge. Pratt trusses were initially built as a combination wood and iron truss‚ but were soon constructed in iron only. The Pratt type successfully survived
