Difference Between Deck Type and Through Type Bridge and Their Components Difference between Deck Type and Through Type Bridge and their Components Naveen Choudhary 1 DEFERENCE BETWEEN DECK TYPE AND THROUGH TYPE RAILWAY BRIDGES • Deck-type bridges refer to those in which the road deck is carried on the top flange or on top of the supporting girders. • Through type bridge - The carriageway rests at the bottom level of the main load carrying members. In the through type plate girder bridge, the roadway or railway is placed at the level of bottom flanges.

  • Polydron-Bridges-Work-Cards.Pdf
    Getting Started You will need: A Polydron Bridges Set ❑ This activity introduces you to the parts in the set and explains what each of them does. A variety of traditional Polydron and Frameworks pieces are used in each of the activities. However, they are coloured to produce more realistic effects. For example, the traditional squares are black and used to represent the road on the bridge deck. Plinth ❑ On the right you can see the plinth or bridge base. All of the bridges use one or two of these. They give each bridge a firm base and allow special parts to be connected easily. Notice the two holes in the top on the plinth. These holes are for long struts. These can be seen in place below. ❑ The second picture shows the plinth with two right-angled triangles and a rectangle connected. All three of these parts clip into the plinth. Struts ❑ There are three different lengths of strut in the set. There are 80mm short struts that are used with the pulleys with lugs to carry cables. These are shown on the left. The lugs fit into long struts. On the Drawbridge 110mm short struts are used with ordinary pulleys and a winding handle. ❑ Long struts are also used to support the cable assembly of the Suspension Bridge and the Cable Stay Bridge. This idea can be seen in the picture on the right. ❑ Long struts are also used to connect the two sections of the Drawbridge. ® ©Bob Ansell Special Rectangles ❑ Special rectangles can be used in a variety of ways.

All the times it is not possible to have 0 degree skew bridge or straight bridge, therefore at certain Construction of bridges is not a new science. Since as situations it is necessary to provide certain amount of skew to per reference earliest bridge available across Nile-river built the bridge. In such situations special attention required to in about 2650 BC. The giant trees felling across natural understand the behavior of bridge. The stresses distribution in streams were the simple bridges to cross streams for ancient the bridge is not uniform and it varies with the skew angle. peoples and that was the basic idea for them to development Few studies shows that up to 20 degree skew angle the of bridges. From this idea they started using timber as basic behavior of the bridge is similar to the straight bridge, but material for bridge building and this has been followed by beyond 20 degree the behavior is quite different.
