ACI 318委员会，结构混凝土建筑规范，已经完成了“结构混凝土建筑规范要求（ACI 318-19）和评论（ACI 318 R-19）”1的技术工作，包括对即将完成的文件的公众意见的回应。这标志着现任委员会成员的五年周期圆满结束。本文介绍了一些变化，以便未来的代码用户知道会发生什么。在讨论这些变化之前，我想感谢委员会的成员们，他们努力工作，使我们走到了这一步（请参阅第25页的致谢）。在本准则周期内，ACI 318委员会由40名投票成员组成，其中包括11名小组委员会主席，他们保持了工作的顺利进行，并为本文中的材料做出了贡献。作为主席，我负责邀请成员加入，我小心地确保投票成员代表学术/教育工作者（32%），顾问（20%），承包商（5%），设计师（22%）和生产商（15%）利益之间的平衡，以及一般利益（5%）。投票成员得到了来自美国各地和ACI 318用户国际社会的72名小组委员会成员的支持。委员会成员包括14名联络委员和5名顾问委员。ACI工程师Greg Zeisler熟练地管理委员会的秘书和行政工作。我很荣幸能够与这样一个有才华、有奉献精神、和谐的团队合作。上一个规范周期的委员会投入了大量的精力和时间对规范进行了一代人一次的重组，导致ACI 318-14.2对于本规范周期，我们主要保留了组织的现状，而是专注于技术变革，以提高安全性，经济性和可持续性，同时引入新技术和想法来推动混凝土行业的发展。以下段落介绍了ACI 318-19的一些关键变化。为了帮助代码用户识别这些和其他更改，在ACI 318-19中，在发生更改的代码和注释文本旁边用竖线标记。
ACI Committee 318, Structural Concrete Building Code, has completed the technical work for “Building Code Requirements for Structural Concrete (ACI 318-19) and Commentary (ACI 318R-19),”1 including responses to public comments on the nearly completed document. This represents the successful completion of a 5-year cycle for the current committee members. This article introduces some of the changes so that prospective future users of the Code will know what to expect. Before getting to the changes, I want to recognize the committee members who worked so hard to get us to this point (refer to the Acknowledgments on p. 25 listing the members). During this Code cycle, ACI Committee 318 comprised 40 Voting Members, including 11 Subcommittee Chairs, who kept the work flowing and contributed to the material in this article. As Chair, I was responsible for inviting the members to join, and I was careful to ensure that the Voting Members represented a balance among Academic/ Educator (32%), Consultant (20%), Contractor (5%), Designer (22%), and Producer (15%) interests, and General interest (5%). The Voting Members were supported by a very active and well-balanced group of 72 Subcommittee Members drawn from across the United States and from the international community of ACI 318 users. Rounding out the committee were 14 Liaison Members and five Consulting Members. ACI Staff Engineer Greg Zeisler deftly managed the secretarial and administrative tasks of the committee. I have been honored to be able to work with such a talented, dedicated, and harmonious group of individuals. The committee from the previous Code cycle devoted significant energy and time to a once-in-a-generation reorganization of the Code, resulting in ACI 318-14.2 For the present Code cycle, we left the organization mainly as it was and focused instead on technical changes to improve safety, economy, and sustainability, while introducing new technologies and ideas to advance the concrete industry. The following paragraphs introduce some of the key changes for ACI 318-19. To help Code users identify these and other changes, they are marked within ACI 318-19 by vertical lines beside the Code and Commentary text where the changes occur.
