Section 1.2.1 of ACI 318 (318M), Building Code Require-ments for Structural Concrete, lists the information that shall be presented on the structural drawings or in the project specifications, which includes the following: 1. Anchorage length of reinforcing steel and location and length of lap splices; and 2.

technical definitions may be found in ACI 116R, “Cement and Concrete Terminology.” bar size number—a number used to designate the bar size. Reinforcing bars are manufactured in both International System (SI—commonly known as metric—measured in milli-meters), and U.S. customary (i n.-lb) sizes. The bar number for

Reinforcing Bars, Reinforcing Details & Tolerances. − Except for a steel‐filled coupling sleeve, ACI 318 requires that the ends of the bars be sawcut, or cut by some other means, within 1‐1/2 degrees of square to the bar longitudinal axis .

Nov 12, 2021 · ACI (American Concrete Institute) has developed guidelines to help in design of reinforced concrete beams. Some of them are given below. 1. Minimum clear spacing between parallel bars in a layer should be equal to diameter of the bar but not less than 1 inch.

Jan 1, 2013 · As per the ACI318 tables for the Development and Splice lengths in the thread http://forum.strukts.com/discussion/1/development-and-splice-length, Top bar in ACI318 is defined as the bar fixed on concrete that is 300mm thick or more.

Most ACI standards and committee reports are gathered together in the annually revised the ACI Collection of Concrete Codes, Specifications, and Practices. This guide provides practical information about the construction of residential concrete that …

Specified 28-day compressive strength of concrete in which the bar is to be developed. Yield strength of bar to be developed. More than 12 in. of fresh concrete placed below horizontal reinforcement. Epoxy-coated or zinc and epoxy dual-coated reinforcement with clear cover less than 3db or clear spacing less than 6db.

The nVent LENTON Headed Bar and Mechanical Anchor Design Aid is provided to facilitate designing reinforcing bar anchorage with the nVent LENTON Terminator and nVent LENTON Ultimate headed bar anchor systems. Since the issuing of ACI 318-08, relevant sections of ACI 318 have been utilized to provide

Fiber-reinforced polymer (FRP) materials have emerged as an alternative for producing reinforcing bars for concrete structures. Fiber-reinforced polymer reinforcing bars offer advantages over steel reinforcement because they are noncorrosive. Some FRP bars are nonconductive as well.

ACI 318-14 20.2.1.1 requires that all bars, except those used in spirals, be "deformed" bars. The deformations referred to are the "bumps" found on reinforcing steel. The presences of these deformations enhances the mechanical bond between the steel and concrete.
