Railway under bridges are specific structures requiring a deep knowledge not only of structural engineering but also of the operations and safety requirements of lines used daily by great number of passengers. It is also important that the cost for the construction is feasible and the structure withstands a maximum of load.Otherwise it may result in great human loss and also economical loss.Thereby,Buildcon provides you an opportunity to put your civil engineering concepts into the practical world by making a model railway under bridge which can withstand large load.
Round 1: Quiz round
Round 2: Here is a challenge to design a RAILWAY UNDER BRIDGE Popsicle sticks and white glueand cardboardas base according to the following constraints which can sustain the maximum load
Construction of given Railway under Bridge involves construction of 4 components i.e,base with railway lines,approach roads,deck and the connections
BASE SPECIFICATIONS It should be basically a simple base structure with railway lines. There is no dimension constraint.
APPROACH ROAD Approach roads are the inclined roads which connect the actual deck making a complete pathway for the running traffic.
1. The approach roads should have a minimum width of 150 mm with maximum 10 mm as the thickness of the road. 2. The horizontal length of the approach roads on both sides is 300mm. 3. These roads are inclined with a slope of 150mm(V):300mm(H) DECK STRUCTURE Deck is the straight portion of the roadway. 1. The minimum width of the deck at any point must be 150 mm.This width does not include the side railing (if at all the side railing is provided). 2. A block of 100 mm X 100 mm will be passed through the space below the deck. 3. The length of the deck must be 700 mm with the maximum thickness of the deck as 10mm.
4. The load will be applied on the middle portion of the deck.
CONNECTIONS Connections will have to made to connect the deck with the approach roads so that they seem to be complete pathway.
The connections are to be made with stated materials only.Any other material used for making the connections stronger will result in elimination of the team. Scoring Criteria 1. Passing of block under the bridge=10 points. 2. Maximum load carrying capacity =30 points. 3. Bridge sustaining the impact load = 20 points. 4. Structural efficiency =40 points. Total marks= 100.
1.How much is the prize money? At the end of the event everyone will be given certificate of participation and the winners will be awarded with prize money.Prize money will be disclosed at the event.
2.Whether the materials will be provided or we need to bring them by ourselves? We will provide all the materials required at the event
3.How will the structural efficiency be calculated? The structural efficiency will be calculated by the following equation. E=Fu/m Where, Fu= Ultimate load attained in competition m=Dead weight of bridge as measured at the competition
4.What should be the shape of the structure? Structure could be of absolutely any shape satisfying the above constraints.
