WPBD Pros and Cons


          As a first time user of West Point Bridge Design I feel that it seems very realistic in most aspects. The ideas of problem solving and design are exemplified well. When given the template to start the bridge design restrictions are also given, with still enough freedom to come up with your own design. When building you can only build up to a certain span length; also our materials were limited, the forces that were able to be supported, and the limit put on cost all made the design project extremely realistic. The program also allows you to modify your design within the set restrictions. The efficiency of building the bridge a certain way was also realistic. If the depth was reduced, the shorter diagonal bars made the bridge more cost efficient.
            There are also some nonrealistic parts of West Point Bridge Design. The program does not take into account effects of weather or fatigue. It does not consider what could happen if there was torrential downpour or very heavy winds. In the program you are able to push the bridge to absolute limit.; to the point where it is barely holding up. In reality this would make a very bad bridge because the bridge would collapse after a year, if it even lasts that long.  Finally, this program only considers if one type of load were to cross at once. What if there are numerous cars or trucks with heavier loads? In that case the bridge would not stay up because the weight would be too much for it to carry.
            Even with these limitations of reality, this program is a good way to start in bridge design. As an individual who has had little to no experience with bridges prior to this, I have learned a lot. It has helped me to look at building and the idea that less is more in better more understandable way.
