7、3FABRICATION OF HYDRAULIC STEEL STRUCTURES08/09*NOTE: This guide specification covers the requirements for general workmanship applicable to the fabrication, assembly and testing of fracture critical Hydraulic Steel StructuresEdit this guide specification for project specific requirements by adding,

8、 deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, whether or not brackets are present.Comments and suggestions on this guide specification are welcome and should be di

9、rected to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).*PART 1 GENERAL*NOTE: This specification i

10、s intended for the fabrication of NEW Hydraulic Steel Structures. Fracture critical hydraulic steel structures (HSS) are critical life safety structures that require added quality control. Fracture critical HSS or components of HSS are those portions whose failure would lead to collapse of the struc

11、ture and potential life loss.The results of the Hydraulic Steel Structures inspection program, undertaken by USACE, has shown that fracture critical fabrication without added oversite has led to a lack of understanding of the techniques required to ensure life safety.SECTION 05 59 13 Page 3Provided

12、by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-This guide specification is intended to ensure fracture critical structures are properly manufactured according to updated welding criteria and ensures that quality control is exercised throughout the fabricatio

13、n process in accordance with ER 1110-2-8157. This specification should be used for the design of fracture critical HSS structures and HSS strutures subjected to dynamic loads. Bulkheads/stoplogs or other HSS structures, not fabricated with fracture critical compoents or subject to static load only,

14、may be fabricated to this specification when an added level of quality control is required. Use of this specification for the repair of existing structures is not recommended and would require numerous modifications to ensure compatibility of existing steel with fracture critical requirements.As of

15、May 2009 all references have been updated to the current edition. The version of the reference being selected is critical considering the need for certain supplements. Changing the version of the ASTM reference such as ASTM A709 will affect the supplement required for toughness testing. For example,

16、 the supplement requirements in the older editions of A709 was S83 and S84. The current edition of A709-08 does not have supplement S83 or S84, S83 applied toughness requirements for non-fracture critical elements, or S84 applied toughness requirements for fracture critical elements. These requireme

17、nts are defined in ASTM A6 Supplement S5 (Charpy Testing) and Section 10 of ASTM A709. Do not change reference years specified without verifying requirements. SPECSINTACT may require the use of an older version depending on the reference database your version of SPECSINTACT is checking against. Be c

18、areful when checking your references.Take great care in adding references to additional steels (ASTM A36, A572, A992 etc.) as these steels do not provide toughness requirements for fracture critical structures and are NOT addressed as acceptable base metals in AWS D1.5. The following items are likel

19、y manufactured from steels that do not comply with AWS D1.5 and must be specifically addressed with a weld procedure generated for qualification such as:1. Rub/Guide Blocks2. Chain3. Pipe or Tubing for Guardrail etc.4. Ancillary items such as anode attachments etc.In all instances where alternate ma

20、terials, other than A709 steel are used, specific weld procedures must be generated to address the mixing of base metals in a given joint configuration. If the engineer chooses to add alternate basemetals to the SECTION 05 59 13 Page 4Provided by IHSNot for ResaleNo reproduction or networking permit

21、ted without license from IHS-,-,-list of approved basemetals then he/she must ensure that these metals are only permitted for individual components where these materials are required and must additionally ensure that pre-qualification records and qualified weld procedures for mixing basemetals are s

22、pecifically required in the submittal section of this guide specification.Note that AASHTO HB-17, Standard Specifications for Highway Bridges, needs to be added to the list of references if slip critical connections and testing are required. See the slip critical testing requirements as defined in t

23、he note provided in the paragraph Bolted Connections. In addition, add reference to ASTM A490 REVA if A490 bolts are specified under that same paragraph. The references to A490 and HB-17 have been removed from this guide specification in order to ensure that the specification compiles properly.*1.1
