WVU Fundamentals of Engineering Program Fall 2019 ENGR 101: Engineering Problem Solving I Project 1: Truss Bridge Design The first project in Engineering 101 this semester is to design a bridge in a variety of ways. One way is to physically test scale models to evaluate different truss configurations, with the results of this initial testing being utilized for a real world application using the West Point Bridge Designer software package. There are multiple deliverables for this project that will be submitted at various times during the 5 weeks over which the project will be completed. Several of these deliverables will be completed individually, while other aspects are team based. If a deliverable does not indicate, always assume it is a task that is to be completed as an individual PHASE ONE: INDIVIDUAL After coordinating with your team mates, each member of the team will design a truss bridge configuration that will span a 29 inch wide gap. The intent here is that there will be four different truss styles investigated by each team. The informatio n from this initial testing is to be used by the team to help in the team in the design of the bridge in Phase Two. Coordination between team members should extend beyond just the type of truss, other factors that should be agreed on include, but are not limited to, how much load to apply to the truss and the locations (minimum 3) that forces need to be measured. Each team member must evaluate a different truss style the following list is of potential designs but not inclusive of all possible designs: • • Warren truss • • Pratt truss • • K-truss • • Fink truss • • Parker truss • • Waddell “A” truss • • Pennsylvania truss In addition, the following topics must be divided such that each team member researches one item, thus the combined background research for the final project report address all four items. • • History of Truss Bridges • • Structural Analysis • • Pier/Bridge Abutment Designs • • Other Applications for Trusses Thus, each member of the team is expected to conduct background research on at least one truss style, and one of the additional topics at the beginning of the project. This background research is expected to cite at least 5 sources, using MLA 8 citation style. Before arriving in the lab to conduct your testing, please review the PASCO SparkVue Getting Started Guide handout. This preliminary testing should lead to a ranking of the four truss designs considered for application in Phase Two. And resulting in the second deliverable from the project, the intermediate report. In the FEP Build Lab (176 ESB, one floor above the Eugene Cilento Engineering Learning Center) are kits of the PASCO Structures System, along with Bluetooth force sensors that will connect with the SparkVue app that is a free app available in Apple and Android AppStores. Having the app installed on your phone would make getting the data faster as you could take it with you when you leave. An iPad with the app installed will be available but shared between all testing areas. In each of the component kits there will be a variety of beams as shown in Figure 1, and a variety of connectors. Before arriving in the lab to test, you need to document what you want to construct as entries in your engineering logbook (Honors Sections) or engineering/graph paper (Non-Honors Sections) as a minimum. Within a one-hour time span, you are expected to build, test, and disassemble your truss. Trusses typically do not have uniform forces in all of the beams, WVU Fundamentals of Engineering Program Fall 2019 thus the requirement for at least 3 different locations tested within the truss. Figure 1: PASCO Structural Beams (24, 17, 11.5, 8, and 5.5 cm) Available in 176 ESB PHASE TWO: In the second phase of this bridge design project your project team is responding to a request from the Department of Transportation, designing a new truss bridge to carry a two-lane highway across the river valley shown in Figure 2. The river valley is 24 meters deep, with an average incline of 63 degrees resulting in an opening at the top of 44 me ters. The results from Phase One are to be used as a means for selection of the basic truss configuration that is to be used in the bridge design. Figure 2: Elevation View of the Proposed Bridge Site The West Point Bridge Designer 2019 software (2016 or newer is sufficient) is to be used to estimate the loads within the truss bridge, as well as the total project cost. Both of these factors will be utilized in the evaluation of which design is the best in the class. Where the Force to Strength Ratio to be used in the calculation is going to be the furthest from a value of 0.5, which corresponds to the target factor of safety of 2.0 as the Force to Strength Ratio is the reciprocal of Factor of Safety. The design score for each bridge design, will be calculated for all bridges that has to successfully withstand the passage of the commercial vehicle at the completion of the project by the instructor. The bridge design software allows for the creation of nodes, or joints between beams, as well as the beams them selves. There are also, a variety of settings that can be changed in the software, such as the type of concrete, the size of the beam s used in the trusses, to name a few. It is up to the design team to choose which values to use for all settings in the West Point Bridge Designer software, as all parameters are factored into both the bridge cost and force to strength ratio.

Introduction
A truss is a structured system used in building or construction to channel the load carried
horizontally from one end to the other, or vertically from roof to the collection center on the
ground (Lianto et al. 2461). It is formed in a triangular configuration to offer a stable balance
that direct the bearded load to a truss force called compressive load. Stiffness and strength of the
truss are increased by combining truss space to space frame structure system widening coverage
space freeing columns in between the ends. This article aims at evaluating the fink truss design
and its application.
