Optimizing a simple bridge structure from a scratch Due date: 30 August 2019 Assessment submission file: PDF file preferred and a video file Assessment submission types: Online Submission for cach student 1. Brief introduction of the project Figure 1 Building site of the bridge in Melbourne CBD This is an individual task for cach student. You are required to conduct a structural optimisation design on a bridge structure using Abaqus to simulate its behaviour. This bridge is supposed to replace one span of an custing Princos Bridge on St Kild. RJ, Melbourne VIC 3(XXI as shown in Figure 1. Google map cowrdinates: -37.819251. 144.9683.40. You should measure the size of the bridge sites using images you snap-shot on google map. You should use the two red lines in Figure 1 as the sale reference. To personalise the assignment, the length of the ruline in Figure 1 is 2m - the last two digits of your student number, ic. if you student number is 33543485, then, the length of the red line is 2.85m. Please indicate the possible error in your measurement 2. Optimization design You should follow the optimization design cycle as illustrated in lecture #to do your design Generally, you will follow two routes. In the first routs, you will act as an optimizer with ESO principle and remove ineNicient materials-ic. regions with lower stress level. You will get an optimal design manually with at least 3 iterations. The second route is to use the 1/3 Matlab code with proper input parameters to get an optimal design. Some detailed guidance and requirements are listed in the following sections. 2.1 Expected design region for optimization You should determine the approximate sizes of the design region to be optimized. You should consider the following factors: . leave some space for the supports of other spans of the Princes Bridge: some decoration space for the handrail: cnough height for the passengers to travel under the designed span: the foundations are rigid enough to be considered as a fixed and support, no underground support will be considered in your optimization design: the bridge will not change along the out of plane direction of Ficure lit san be
