Design Brief Design a bridge in WestPoint bridge
builder. Minimal overall cost. If bridge is below 24m, excavation of
river banks is required. The highest point must not exceed
8.5m above the river banks. Must be constructed of no more than
50 joints and no more than 120 members.
Design Brief Bridge deck must be 10m wide to
accommodate traffic. May choose from different member
materials. May choose either hollow or solid
members. Must be able to support its own weight
along with a 480kN load from passing traffic.
Design Brief Bridge can either have one lane or
two lanes on the deck. The bridge must comply with safety
provisions of the 1994 LRFD AASHTO Bridge Design Specification.• Material densities• Load combinations• Tensile strength of members• Compressive strength of members
Research Summary Deck Elevation 8 meters- $75,200 High-Strength concrete- $5,000 Quenched Hollow tube- $32,764.18 Product cost- $6,000 Excavation cost- $67,000 Abutment cost- $24,800
Total cost- $165,764.18

Final Design This design of bridge was decided to
be the final design because it was the cheapest and most versatile bridge design.
it also follows all of the constraints listed in the design brief.
