In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object" (Costanzo, 2013). Trusses have been used in various applications like building bridges, roofs, etc. since 1800s. Before 1800, nearly all bridges and roof supports were made of stone arches. Bridges and roofs made out of stone arches are effective but very costly to build. Furthermore, stone arches are strong structures but they
A truss bridge is one that is composed of triangular patterns formed from either metal or wooden beams. Each individual member of the truss component of the bridge is subject to compression and tension from either ends of the actual structure. The top beam will always receive the most compression while the bottom beam receives the most tension. The triangular composition allows for the weight of the bridge and its load to be transferred because triangles are stable shapes. They have three lengths
I built a truss bridge. I built a truss bridge because I thought it would be the strongest under the weight of the bridge crusher. My bridge design was accepted. It was accepted because it held all of the weight without issue and it followed my design. The truss underneath the bridge added a lot of strength to the bridge. Layering the popsicle sticks also added a lot of strength. My bridge was designed to have a truss system below the deck with popsicle sticks going directly from the bottom into
with a river. The masses they convey are, with regards to toll road or railway bridges, pretty modest, and in most circumstances a reasonably light structure is needed. They are, but, often required to give a protracted clear span, and stiffness then becomes an crucial consideration. The bridges are frequently required very virtually on view to the general public and consequently the advent
