Application of classroom skills + necessary career management skills in the field

Areas of JudgmentOral PresentationDesign PaperFinal ProductThe College of New Jersey Department of Civil EngineeringProblem StatementGeneral: Create a canoe that is suitable for transportation and competition

Design a suitable hull that will hold the required passengers

Design a concrete mix that will meet the structural requirements

Build a canoe in an efficient and timely manner

Structural SpecificationsAnalyzed the canoe as a beam with symmetric point loads against a distributed buoyant force

Used an average weight of 160lbs for each scenario

Analyzed with a buoyant force of 31.22 lb./ft. (4 rowers)

Center of Gravity (x direction)= 10.04 from sternCenter of Gravity (y direction) = 0Center of Gravity (z direction) = 0.577 = 6.9The College of New Jersey Department of Civil EngineeringStructural Analysis2 Rowers

The College of New Jersey Department of Civil EngineeringWhat is Shotcrete?Invented in the 20th Century for taxidermy Concrete is conveyed through a hose and pneumatically projected at high velocity onto a surfaceUses: infrastructure repair, slope stabilization, artificial rockscapes, swimming poolsEase of application onto unique surfacesThe College of New Jersey Department of Civil EngineeringShotcrete vs. Hand-PlacementShotcreteSelf-compacting Increases the strengthEfficiency of placement for reinforcing fibersHigher density due to loss of air voidsSmaller aggregate used in order to make the mix flowableWater is added at the nozzle Hand-PlacementCompacted and placed by many handsReinforcing fibers are applied in a 2D fashionDensity remains closer to theoretical densityLarger aggregate able to be usedWater is added with the batch before applicationThe College of New Jersey Department of Civil EngineeringBenefits and DrawbacksBenefitsEase of ApplicationRequires one nozzlemanRequires same amount of material as other methods30-40% Increase in strength Alignment of reinforcing fibersNot widely used - Ingenuity!

DrawbacksRequires skilled nozzlemanASA Certified Nozzleman will be usedRequires specialized carousel hopper pumpDifficulty of keeping W/C ratio consistent
