Design Project 1 Replacement of Vehicle Bridge over

Design Project #1 Replacement of Vehicle Bridge over Spring Creek Centre County, PA Introduction to Engineering Design EDGSN 100 Section 001 This is Howe We Do It™ Design Team 6 Brianna Bannister Tim Hogan Eric Lopez Eric Johns Doug Pisarek E Presented to: Prof. Berezniak Spring 2017

Statement of the Problem ● Recent 100 year flood ● Destroyed a structurally deficient bridge ● located over Spring Creek, located near Puddintown Road in College Township, Centre County PA. ● bridge provided vital access to the Mount Nittany Medical Center for residences, ● hinders first responders as a 10 mile detour is required due to destruction of the bridge

Project Objective ● Pennsylvania Department of Transportation of (Penn. DOT) Engineering District 2 -0 ● requires a new bridge design to replace the one destroyed by the flood

Required Design Criteria Penn. DOT District 2 -0 requires that the bridge must include ● Standard abutments ● No piers ● Deck material made from. 23 meter thick medium strength concrete ● No cable anchorages ● Hold load of two AASHTO H 20 -44 trucks in each lane of traffic ● Deck elevation of 20 m and span of 40 m ● Design for both Warren and Howe truss bridge

The Technical Approach Phase 1: Economic Efficiency - Engineering Encounters Bridge Design 2016 - Price goal – Below 300, 000$

The Technical Approach Phase 2: Structural Efficiency Howe Truss Bridge Warren Truss Bridge ● Maximum of sixty standard Popsicle sticks ● Elmer’s white glue ● Hot glue to attach the eight struts

The Results Phase 1: Economic Efficiency Final Howe cost $261, 937 Final Warren cost $224, 033

The Results Phase 2: Structural Efficiency Howe truss bridge Warren truss bridge Average Structural Efficiency 316 266

The Best Solution ● Through testing of both the Warren and Howe designs, it was determined that the Howe design is the optimal replacement. ● This conclusion was made due to the Howe Bridge’s higher structural and design efficiency. Giving residences a safer, more stable, and structurally efficient bridge.

Our Conclusions -Howe Bridge: $37, 904. 06 more expensive than Warren Structural Efficiency -Both lower than $300, 000 limit Howe: 316 Warren: 266 Design Efficiency Howe: 666. 50($/SE) Warren: 1, 009. 16($/SE)

Our Recommendations Recommended bridge design: Howe -More stable, safer, and structurally efficient -Worth the higher price Next Steps -Finalize design and pricing with This is Howe We Do It™ ←-Howie Mandel, satisfied customer
