Title
Incorrect Strength Reduction Factor of the Compression Member in the ACI 318 Code
Abstract
The ACI Committee 318 should correct the strength reduction factor of the compression member.
Keywords: Strength Reduction Factor
I. Introduction
Since 2002, the ACI 318 Codes (2002, 2005, 2008, 2011, 2014, and 2019) have adopted the un-fixed strength reduction factor of the compression member, and should be corrected to maintain the stable pre-defined failure probability.
II. Conclusion
The ACI Committee 318 should correct the strength reduction factor of the compression member.
