Every year the members involved in American Society of Civil Engineers participate in multiple competitions such as steel bridge, concrete canoe, environmental, and more. The competitions aren’t until March; however, we have to begin working now so that our teams will be ready for competition.

This year I am captain of our steel bridge team. For the steel bridge competition we have to design a 1/10 scale model of a steel bridge and every year the criteria are changed. This year we have to design a bridge that has an 18-foot clear span which means that the supports are only on the ends of the span. During the competition we are challenged to subject our bridge to various forms of loading.

To begin design we have to carefully read the rules. As a group we all suggest different ideas and begin to build off of them. This year we decided to go with a beam bridge design. As a group we are planning that we will use a built up T-member made from two L-members for the bridge decking. Our biggest challenge so far is to design the way to brace the bridge laterally. Lateral bracing is used to prevent side sway. After we decide what we would like to do for bracing our next step will be to make all shop drawings and then next semester we will begin fabrication.
