海外工程十五年之一0三——美标混凝土结构设计概述(2)

《美国建筑混凝土结构规范》(含条文说明)最新版本为 ACI318-19,英文名字为Building Code Requirements for Structural Concrete (ACI 318-19)。318-19版国内无翻译版发行。为使大家更好的理解,特别翻译其关键章节,不妥之处,敬请读者提出宝贵意见。本文为扉页的部分重点翻译。


ACI 318-19前言

The “Building CodeRequirements for Structural Concrete” (“Code”) provides minimum requirementsfor the materials, design, and detailing of structural concrete buildings and,where applicable, nonbuilding structures. This Code was developedby anANSI-approved consensus process and addresses structural systems, members, andconnections, including cast-in-place, precast, shotcrete, plain, nonprestressed,prestressed, and composite construction. Among the subjects covered are: designandconstruction for strength, serviceability, and durability; loadcombinations, load factors, and strength reduction factors; structural analysismethod; deflection limits, mechanical and adhesive anchorage to concrete;development and splicing of reinforcement; constructon document information;field inspection and testing; and methods to evaluatethestrength of existingstructures.

    《建筑混凝土结构规范》(“规范”)规定了建筑和非建筑结构混凝土结构(如适用)的材料、设计和构造的最低要求。本规范是由ANSI批准的共识过程制定的,涉及结构系统、构件和连接,包括现浇、预制、喷射混凝土、素混凝土、无预应力、预应力和组合结构。课程包括:强度、适用性和耐久性的设计和施工;荷载组合、荷载系数和强度折减系数;结构分析法;挠度限值、混凝土机械锚固和粘结锚固;钢筋的锚固和搭接;施工文件信息;现场检查和测试;以及评估现有结构强度的方法。

The Code was substantiallyreorganized and reformatted in 2014, and this Code continues and expands thatsame organizational philosophy. The principal objectives of the reorganizationwere to present all design and detailing requirements forstructural systems orfor individual members in chapters devoted to those individual subjects, and toarrange the chapters in a manner that generally follows the process andchronology of design and construction. Information and procedures that are commonto the design of multiple members are located in utility chapters. Additional enhancementsimplemented in this Code to provide greater clarity and east of use include thefirst use of color illustrations and the use of color to help the user navigatethe Code and quickly find the information they need. Special thanks to BentleySystems, incorporated, for use of their Pfoconcrete software to produce many ofthe figures found in this Commentary.

本规范于2014年版进行了实质性重组和排版,本版规范继续并扩展了相同的组织理念。重组的主要目标是在专门讨论这些个别主题的章节中提出结构体系或构件的所有设计和构造要求,并遵循设计和建造过程和顺序的方式布置章节。构件设计的通用信息和方法,请参阅相应章节。本规范实现的其他增强功能提供了更高的清晰度和使用效率,包括首次使用彩色插图和使用彩色来帮助用户浏览规范并快速找到所需的信息。特别感谢Bentley Systemsincorporated使用他们的Pfoconcrete软件制作了本条文说明中的许多内容。

Uses of the Code includeadoption by reference in a general building code, and earlier editions havebeen widely used in this manner. The Code is written in a format that allowssuch reference without change to its language. Therefore, backgrounddetails orsuggestions for carrying out the requirements or intent of the Code provisionscannot be included within the Code

itself.The Commentary is provided for this purpose.

本规范可以作为一般建筑规范的参考,并且先前版本已经广泛被其他的规范所引用。本规范按照特定的格式进行编写,使得其参考的部分无须以规范的语言进行描述。因此,本规范不包括对于任何背景的详细描述、执行规范要求的建议或规范的目的。而规范的条文说明对此进行了说明。

Some considerations of thecommittee in developing the Code are discussed in the Commentary, with emphasisgiven to the explanation of new or revised provisions. Much of the researchdata referenced in preparing the Code is cited for the userdesiring to studyindividual questions in greater detail. Other documents that providesuggestions for carrying out the requirements of the Code are also cited.

为了强调对新编或者修订规定进行,条文说明还包括委员会对规范相关看法的讨论。编写规范时,所引用的大多数研究数据则是为了方便使用者更详细地进行学习和参考。同时规范中还引用了其他关于执行规范要求的建议性文件。

Technical changes from ACI318-14 to ACI 318-19 are outlined in the August 2019 issue of ConcreteInternational and are marked in the text of this Code with change bars in themargins.

ACI318-14ACI 318-19的技术变更在20198月发行的《国际混凝土》中进行了说明,在本规范的文本中用变更栏标记。
