Designing Reinforced Concrete Columns

摘要

The 2002 edition of ACI 318, "Building Code Requirements for Structural Concrete and Commentary," adopted the Unified Design Method, which may be used to analyze both reinforced and prestressed concrete members. ACI Committee 318 also changed the load factors and modified the strength reduction factors φ. This article focuses on the strain-based approach to column design as presented in ACI 318, Section 9.3.2.2. Here, I propose design graphs for analyzing and designing columns whose net tensile strain e is in the transitional zone.
