Title: What Do We Know About Confinement in Reinforced Concrete Columns? (A critical review of previous work and code provisions)
Author(s): Koji SakaiI and Shamim A. Sheikh
Publication: Structural Journal
Appears on pages(s): 192-207
Keywords: axial loads; building codes; columns (supports); ductility; confined concrete; earthquake-resistant structures; reinforcing steels; moment-curvature relationships; reinforced concrete; reviews; Structural Research
Abstract:Based on an extensive review of literature, a state-of-the-art report on concrete confinement is presented that aims at defining the status of the problem and the future direction of work, including revision of design codes' provisions. Topics discussed include properties of confined concrete, behavior of confined sections and columns including plastic hinge regions, and a critical evaluation of the design codes' provisions. With the reinterpretation of previous data in light of the results from recent tests, apparent contradictions on the effects of several variables have been explained. Several areas in which the design codes' provisions need revisions have been identified. An extensive list of references on related topics is also included.
