(1) EN 1993‑1‑8 provides rules for structural design of joints subject to predominantly static loading using all steel grades from S235 up to and including S700, unless otherwise stated in individual clauses.
NOTE As an alternative to the design rules provided in Clause 9, the design rules given in CEN/TS 1993‑1‑8011 “Eurocode 3: Design of steel structures — Part 1-801: Hollow section joints design according to the component method” can be used.
(2) The provisions in this document apply to steels complying with the requirements given in EN 1993‑1‑1 and to material thickness greater than or equal to 3 mm, unless otherwise stated in individual clauses.

Classification and other requirements are specified for numerous grades of flux cored and metal cored stainless steel electrodes and rods. New classifications include a duplex alloy and three high carbon classifications not previously classified. New classifications also include all of the metal cored electrodes that are currently in A5.9/A5.9M. In the next revision of A5.9/A5.9M these metal cored electrodes will be deleted from that specification.
Designations for the flux cored electrodes and rods indicate the chemical composition of the weld metal, the position of welding, and the external shielding gas required (for those classifications for which one is required). Designations for the metal cored electrodes indicate the chemical composition of the weld metal only.
The requirements include general requirements, testing, and packaging. Annex A provides general application guidelines for individual alloys and other useful information about welding electrodes. ANSI Approved. approx. 70 pages. ISBN: 978-0-87171-800-6

This document presents a detailed discussion of the metallurgical characteristics and weldability of many grades of austenitic stainless steel used in piping and tubing. The delta ferrite content as expressed by ferrite number (FN) is explained, and its importance in minimizing hot cracking is discussed. Several figures and tables illustrate recommended joint designs and procedures. Annex A presents information on the welding of high-carbon stainless steel cast pipe and fittings.

This guide provides background and examples on the use of practical aggregate grading tools to improve aggregate performance in concrete and allow the paste content of a concrete mixture to be reduced while achieving satisfactory workability and physical properties. The aggregate grading of a concrete mixture impacts the workability, durability, strength, and sustainability of concrete. These grading tools can also be used to proportion concrete mixtures as well as troubleshoot issues associated with mixtures from high to low workability. This guide does not make recommendations, but it does describe and give examples on how to use these tools.

ACI PRC-(349-359)-24: Design of Nuclear Safety-Related Structures for Impactive and Impulsive Loads using ACI CODE-349 and ASME Section III, Division 2 Provisions
This guide is the work of the ACI 349/359 Task Group on Impulsive and Impactive Loading that established a proposal of updated design provisions for both ACI CODE-349 and ASME BPVC Section III, Division 2. The provisions of this guide are nonbinding on ACI CODE-349-23 Appendix F or ASME BPVC Section III, Division 2:2011 and may change if implemented.
This guide gives the genesis of the provisions that are proposed to be incorporated into these code documents and further explains why these provisions were adopted. Furthermore, the primary mandate of this guide was to align both aforementioned codes and to bring these codes up to date with current industry practices, using current references for the provisions of both code documents. This guide serves as an independent report of the task group’s work to the code committees. This guide is issued as a detailed commentary to the provisions of ACI CODE-349-23 Appendix F or ASME BPVC Section III, Division 2. The language of ACI CODE-349-13 and ASME BPVC Section III, Division 2:2011 form the starting point for the proposed nonbinding revisions already incorporated in the first two columns of this guide. The last column does not provide proposed changes but provides explanations of why such changes are proposed.

Size: 547.34 MB
NEW:
Piping Design
- Handling of ASME B31J is enhanced, giving the ability to control when to apply Note 3 from Table 1-1. This is applicable when calculating the flex factors for 90 degree bends and elbows that match the thickness of the adjacent pipes.
- ASME B31.12- 2023 has been added.
Drafting:
- Users can now select tees in the model based on the assigned tee type.
