美国ACI钢筋混凝土结构设计规范不仅在美国而且在世界范围内均有广泛影响,许多国家的钢筋混凝土结构规范常引用其中某些公式。因此,学习美国ACI规范设计方法可收到触类旁通的效果。本文着重介绍美国ACI 318-83钢筋混凝土结构设计规范关于基本构件的设计方法,包括基本假定、公式来源和特点以及有关规定,配以计算例题,以便设计人员能尽快地熟悉并掌握这种设计方法。凡与我国设计方法不同之处,则详加叙述,并尽可能与我国新修订的规范以及“74”规范进行比较,以利掌握。——编者
The American ACI reinforced concrete structural design code has not only extensive influence in the United States but also in the world. In many countries, the reinforced concrete structure specifications often refer to some of the formulas. Therefore, learning the American ACI specification design method can receive the effect of analogy. This article focuses on the design method for the basic components of the US ACI 318-83 design specification for reinforced concrete structures, including basic assumptions, formula sources and characteristics, and related regulations, together with calculation examples, so that designers can quickly familiarize themselves with this design method. . Anything different from our country’s design method is described in detail, and as far as possible, it is compared with China’s newly revised norms and the “74” specification to facilitate the mastery. --editor
