ENG1020 – ENGINEERING STRUCTURESProject 3Investigation of an Alternative Elevated Pedestrian BridgeSandani Manjana Jayaratne – 24848352Eranda Sampath Kulatunge – 24717150Muhammed Akif Mazlan – 2584903430 May 2014SummaryThis report examines the calculations performed to make an informed decision on which design is best suited for an elevated pedestrian bridge. The bridge will be built between Building 5A and Building 4 at Monash University Malaysia. The client requested an alternative girder design for the bridge to the initial truss design. This report shows an overview of the calculations, plans and methods involved in the design of the elevated pedestrian bridge.

The initial design of the bridge was truss. However, the customer requested an alternative beam design. The report explains the two projects in detail and which project is best suited for purpose. Project 2 (beam project) shall be constructed with steel beams, with a column in the midspan. For this reason, the beams were optimized before designing the column. Safety was considered a top priority among other vital factors carefully planned during the design of the bridge. To ensure safety, the initial estimate of the beam's self-weight of 50 kg/m was repeated several times until an adequate value was obtained. The beams were checked for...... half of the paper ......ion is less than the maximum allowable deflection of 0.048 m, so the beam does not break Center Column Design Force/Area < σ stress (102 .37 x 〖 10〗^3)/A < 350A > 292.48 mm^2To test the deformation effect:F < (ELπ^2)/L^2I > (FL^2)/(π^2 E )I > (102.37 x 〖10〗 ^3 x 〖5400〗^2)/(π x 200 x 〖10〗^3 )I > 1.90 x 10^6 mm^4So 114.3 was chosen x 3.6 CHSConclusionThe final conclusion was reached by calculating and measuring which radius would be best suited to support the bridge. The suitable beam was found to be 310UB: 32kg/m while the central column was found to be 114.3 x 3. 6CHS Overall, the final conclusion we reached was that using a truss bridge is a more suitable design for the connecting bridge.ReferencesLesson notes: Sunway and ClaytonAppendix 1 – Sections with I-beamsAppendix 2 – Circular hollow sectionsAppendix 3 – Square hollow sectionsStudy guide ENG1020
