Design Brief �Design a bridge in West. Point bridge builder. �Minimal overall cost. �If bridge is below 24 m, excavation of river banks is required. �The highest point must not exceed 8. 5 m 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 10 m 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 480 k. N 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
