Analysis and Design Project There are small villages along the banks of the river Jhelum close to Sri Nagar Road in Azad Jammu and Kashmir (as shown in Figure 1). The people of these villages generally need to go across the river to meet their relatives living on the opposite side and to purchase grocery and related items as well. The previous means of bridge was an old bridge which has been damaged and is unreliable. A national charity organization with the support of the local government initiated the step to build a permanent pedestrian bridge comprising of steel trusses, keeping in view the safety and reliability. The river flows through this region in a gorge with a varying depth from 100-300 feet. The selected location of the bridge site at Chinari has a width of 30m between the two ends of the river as shown in the schematic sketch below (Figure 2). The bridge may comprise of two trusses as supporting structures for a deck made up of timber planks. Assume that the trusses are simply supported and the load on the deck is equally distributed between the two trusses. Therefore, only one truss needs to be designed which will be replicated on the other side of the deck. The load to be considered for the design of the pedestrian bridge is due to the people walking over it with their daily grocery items as well as occasional gifts for their relatives. To maintain safety for pedestrians, the side railings will be welded with the vertical/inclined members of the truss, making it necessary for the deck to be at the level of bottom chords of the trusses. Since this bridge is over a gorge; therefore, wind loads needs to be considered in the design accordingly. Further, this area lies in high seismic zone and has seen devastation in 2005 Kashmir earthquake. Your services are required for the design of the truss and its members only. You can happily leave the connections (welded connections) and supports design for another volunteer.
