Full Description

D1.1 spells out the requirements for design, procedures, qualifications, fabrication, inspection and repair of steel structures made of tubes, plate and structural shapes that are subject to either static or cyclic loading.

In addition to the editorial changes to the text and commentary to improve clarity and understanding of the provisions of the code, the following have been undertaken in the D1.1:2015 edition:

General:All tubular provisions, tables, and figures moved to a new "Tubular Structures" Clause and corresponding new section of commentaryIncorporation of AWS A5.36, Specification for Carbon and Low-Alloy Steel Flux Cored Electrodes for Flux Cored Arc Welding and Metal Cored Electrodes for Gas Metal Arc WeldingSteels not recommended for PWHT: added ASTM A709 Grade HPS 100W [HPS 690W] and deleted ASTM A709 100 (690) and 100W (690W)Design:Clarification regarding calculation of effective throat of a combination PJP flare bevel groove weld and fillet weldAdditional provisions for wrapping welds on opposite sides of a common plane to permit seal weldingFatigue curve cases and figures revised to align with AISC 360Qualification and prequalification:Clarification of conditions for backing other than steel in prequalified WPSsReorganization and update of tables for prequalified base metals and filler metals and alignment with table for prequalified preheat and interpass temperatureNew figure for prequalified fillet weld joint detailsNew figure for prequalified CJP groove, T-, and corner jointsClarification of CVN Test requirements for sub-sized specimensFabrication:Clarification of baking requirements for low-hydrogen electrodes for ASTM A514 and A517 steelsClarification of preheat and interpass temperature requirements for combinations of base metalsUpdated requirements fo rbacking and for substrate cleanlinessClarification of provisions for oxygen gougingClarification when locations of the depth of the web from tension flanges of beams or girders are considered outside the tension zone for tack welds and construction aid weldsRevisions to the location and sequence of member and element splicesClarification of weld profile requirementsInspection:Clarification regarding retesting based on quality of workNew table for qualification and calibrations requirements of U/T equipmentClarification regarding calibration for sensitivity and horizontal sweep of U/T equipmentAnnexes:New figures to clarify effective throat for various joint types and combinationsTerms and definitions are now normativeSample welding forms extensively revisedSafe practices has been deleted - Clause 1 includes references for safety
