At least 1 inch clearance shall be provided between the bridge and lock walls. Bridge shall be designed in accordance with the AISC ??????Manual of Steel Construction: Allowable Stress Design?????? and AIS C ??????Hollow Structural Sections Connections Manual?????? latest edition. AASHTO ??????Standard Specifications for Highway Bridges?????? shall be used for live load distribution and loading combinations. In addition to normal dead loads, the bridge shal l be designed for the following: Pedestrian uniform live load of 85 pounds per square foot. Fully loaded Clark fork lift model CDP 30 using the following criteria for analysis: Combined fork lift and load weight of 14,000 pounds plus 10% impact applied to one axle, track dimension of 3'-4???? inch (center of tire to center of tire), tire footprint of 9 inches perpendicular to bridge span and 6 inches parallel to bridge span under full load with impact. Pedestrian live load and vehicle live load need not b e combined. Minimum wind load of 35 pounds per square foot. The wind shall be calculated on the entire vertical surface of the bridge as if fully enclosed. Temperature differential of 120 degrees Fahrenheit. Differential movement of ???? inch of the lock walls. The vertical deflection of the bridge due to pedestrian live load shall not exceed 1/400 of the span length. Deflections due to vehicular live load need not be considered. The horizontal deflection due to lateral wind load shall not exceed 1/500 o f the span length. The contractor shall specify the maximum load capacity for a two axle vehicle with equal loading to each axle, axles spaced at 7??????, wheel transverse spacing at 5??????. MATERIALS: All structural members shall have a minimum thicknes s of 3/16 inch.
