 The team just submitted the Report for the Supplemental Competition. In this report, the team goes over teh design process, design innovations, analysis, and construction sequence of the project. For the analysis, free body diagrams, shear and moment diagrams, internal load effects, load stability, and vertical deflection were all calculated. All of these calculations are seen in the appendix of the report, after the fabrication drawings.

The Team met to film the video about our design that is required for the Supplemental Report. The video displays the Design, Analysis, and the Construction Plan for the bridge. The Team will continue to polishing the report and finish the hand calculations.

The team has been preparing for the Supplemental Report. The group has been focusing on creating the CADD drawing for each member as well as a CADD drawing for the our construction plan. The CADD drawings for each member is a more detailed depiction of the bridge compared to the Visual Analysis bridge. These files would also be used if the bridge would be manufactured. Sofia Zapata would create the stringers while Hunter Kelly would create the overhead truss and footings. The CADD drawing for the construction process is used to visualize the planned process if we were to participate in the in-person competition. This CADD drawing was created by Steven Hippauf.

American Institute of Steel Construction released the rules for the compete from home competition. The main change of the rules was that deflection was no longer used in the scoring and was instead a requirement for competition. The bridge had to maintain a deflection of less than 3". Andrew Agresto created a new design that would be optimized for the rule change that was similar to Matthew Chaber's original design. The team decided to participate in the Supplement Competition as we have faith in Andrew's Design.

A final design for the Stringer and Overhead Truss connection. For the string connection, we have designed a Twist - Lock Connection with simple dimensions which will allow for easy manufacturability. For the Overhead Truss we will be using a sleeve connection for its simplicity and low weight.

Over the course of the past month, the Team has been talking with Penn Steel Fabrication Inc. about a possible sponsorship. Last week, Penn Steel Fabrication Inc., responded back that they would sponsor the project. The team has sent out the materials list for our bridge design which will take up to three weeks to be ready to be picked up.

The Team met on campus at the Stem building to discuss and test the strength of the connections used in last years design. The team, along with the supervision of Joseph Zanetti, loaded the previous years design with five barrels of water that had a total load of 1000 lbs. The deflection at the center point of the bridge was close to 1.7 inches. We understand the quick construction of last years connections but the large deflection has discouraged the Team from using that design.

The Team has finished working on our alternative designs. Each member has created a design, two under-trusses and three over-trusses, focusing on the deflection, weight, and constructability. Alternative Design #1 was created by Steven Hippauf focusing on getting an under-truss with a low enough deflection to compete with over-trusses. Alternative Design #2 was created by Andrew Agresto focusing on the simplicity of previous years winners. Alternative Design #3 was created by Sofia Zapata focusing on using the leftover materials from last year. Alternative Design #4 was created by Matthew Chaber focusing on creating the simplest bridge possible. Alternative Design #5 was created by Hunter Kelly focusing on constructability around the river.  These designs were analyzed and presented to the Civil Engineering Faculty. The team has determined Alternative Design #2 was the best and we will continue improving and optimizing the design.

The Team has begun creating their different bridge designs. To create the designs the team is using Visual Analysis, version 19. The program can display the weight and displacement of the bridge. Displayed below is a screenshot of Hunter's design so far.

The fundraising letter is being revised, hopefully to be sent out soon. The team has begun talks with a possible sponsor and with AISC in hopes of getting a company to assist in manufacturing.

The team has begun a fundraising draft to obtain the $6,750 that was estimated to construct the bridge and participate in Regional and National Competition. The letter is planned to be sent out to 20 companies in the area or that the members have contact with. To aid in fundraising, the Team Leader Steven Hippauf, has contacted the American Institute of Steel Construction about possible fundraising and fabrication opportunities.
