Desinging Bridge

Once again, we need to do the challenging project asking us to do the pedestrian bridge in the civil engineers way. Am going to take the mechanical stream, but still to learn some of the civil engineering thing. The project asked us to design a pedestrian bridge using the equivalent trusses due to the load the bridge will have. The design should be accurate and may be able to face the worst-case scenario, let say there's lots of people staying on the bridge. Obviously I hate the calculating part but there's a thing I like - doing the sketch of the bridge on the computer. I were recommended bu the tutor to use the Autocad but since I dont have the basics, I use Google SketchUp Pro 7 and still the 3D model doesnt created very well, it suppose to provide grids on the sketching pad. Luckily the Google layOut provides what we want. And here's our first attempt using this kinda software. should be better, hopefully.

We did some research to some of the pedestrian bridges around Sunway to get the real imaginery of our bridge.
