STUDENT STEEL BRIDGE COMPETITION

2012 RULES

1

MISSION
The mission of the Student Steel Bridge Competition (SSBC) is to supplement the education of civil engineering students with a comprehensive, student-driven project experience from conception and design through fabrication, erection, and testing, culminating in a steel structure that meets client specifications and optimizesperformance and economy. The SSBC increases awareness of realworld engineering issues such as spatial constraints, material properties, strength, serviceability, fabrication and erection processes, safety, aesthetics, and cost. Success in inter-collegiate competition requires effective teamwork and project management. Future engineers are stimulated to innovate, practice professionalism, and usestructural steel efficiently.

WELCOME
ASCE and AISC support and encourage the equitable opportunity for participation by all interested and eligible individuals in the Student Steel Bridge Competition without regard to race, ethnicity, religion, age, gender, sexual orientation, nationality, or physical challenges. Bridge teams should be inclusive and open and fair to all interested and eligibleparticipants.

Section 1 INTRODUCTION
Students design and erect a steel bridge by themselves but may seek advice from faculty and student organization advisers. Students gain maximum benefit if they fabricate the entire bridge themselves. However, because appropriate shop facilities and supervision are not available at all universities,students may use the services of a commercial fabricator provided that they develop the work orders and shop drawings, and observe the operations. Students are encouraged to maximize their involvement in fabrication. Safety is of primary importance. AISC and ASCE request that competitors, advisers, hosts, and judges take all necessary precautions to prevent injury to competitors, judges, hostpersonnel, and spectators. This document describes the competition and states the rules for competitions conducted during 2012 at both conference and national levels. It is available at http://www.aisc.org/steelbridge, together with revisions, clarifications, other information, and the form for submitting requests for clarifications. Information at this site takes priority over any other source except asnoted herein. The rules are changed every year to enhance the competition and ensure that competitors design and build new bridges. The rules are intended to be prescriptive but may require some interpretation. The procedure for requesting clarification of the rules is described in section 14, “Interpretation of Rules.” Competitors, judges, and host personnel are encouraged to read this Rules...
