471-5 Design Criteria.
471-5.1 Wales: Wales must meet the following minimum design criteria:
1.Be structurally continuous across a minimum of two spans.
2.Recess all at tachment hardware.
3.Provide sufficient creep resistance to prevent loosening of attachments over time.
4.Provide adequate stiffness to distribute vessel impact loading so as to achieve the maximum efficiency of the system.
5.For hollow wale secti ons, provide a minimum bolt pull -through and crushing resistance greater than or equal to the maximum connection reaction force. Pull -through and crushing resistance is defined at the point of first yield and/or the load at which an audible crack occurs.
6.Hollow w ale sections must be capable of resisting crushing loads perpendicular to the axis of the member as required for the impact force applied to fender in the analysis used to determine the associated energy absorption capacity of the system. This impact force may be equally distributed between two lines of wales and over a longitudinal distance of five feet.
7.Provide black wales unless otherwise shown in the Plans.
8.Wales must meet the RTSS minimum requirements in Section 973, Table 973-4.
471-5.2 Piles: Piles must meet the following minimum design criteria:
1.Recess all attachment hardware.
2.Provide sufficient creep resistance to prevent loosening of attachments over time.
3.For hollow pile sections, provide a minimum bolt pull -through and crushing resistance greater than or equal to the maximum connection reaction force . Pull-through and crushing resistance is defined at the point of first yield and/or the load at which first crack occurs.
4.Provide black p iles unless otherwise shown in the Plans. FY 2023-24 Return to Table of Contents
471-6 Storage, Handling and Installation .
Unless otherwise shown in the manufacturer’s approved field construction manual, use the following construction details. Protect materials at all times against exposure to extreme he at or impact. Transport products in a manner that will minimize scratching or damage to the outer surfaces, stack on dunnage above ground so that it may be easily inspected and store in a manner that will avoid damage. Handle and lift products with nylon s lings. Do not use sharp instruments in handling the product. Products damaged in shipping or handling will be rejected. Products containing cracks in the reinforcing rods , or cracks or splits (partial or full depth) across the section will be rejected. Cut, bevel, drill, countersink and otherwise install products in accordance with the manufacturer’s recommendations. Set all material accurately to required levels and lines, with members plumb and true and accurately cut and fitted. Securely attach all mat erials to substrate by anchoring and fastening as shown in the shop drawings . Perform all cutting and drilling in a manner that allows for the collection of all debris and dispose of properly. Install piles in accordance with Section 455.
