Design Guide - 152 pp.; 1st Edition
The objective of this guide is to provide comprehensive information on the design and detailing of reinforced concrete columns in buildings assigned to any Seismic Design Category. The design and detailing requirements in ACI 318-14 are clearly summarized in tables and figures for quick reference. Numerous design aids and flow charts are provided that can be used to determine the size of the cross-section and the required amounts of longitudinal and transverse reinforcement for members subjected to axial compression or combined flexure and axial compression. Slenderness effects are also covered, including methods on how to size a column so that such effects can be neglected. A collection of design strength interaction diagrams are given in an appendix that covers tied, rectangular columns ranging in size from 12 to 48 in.; tied and spiral circular columns ranging in diameter from 12 to 48 in.; Grade 60 and Grade 80 longitudinal reinforcement; concrete compressive strengths from 4,000 psi to 14,000 psi; and longitudinal reinforcement ratios from 1% to less than 2.5%. Numerous worked-out examples illustrate the proper application of the code provisions and demonstrate the use of the design aids.
