Concrete Journal, Vol.59, No.11, Nov. 2021
- Synopsis
- The “Recommendation for Mix Design and Construction Practice of Concrete Filled Steel Tubular Structure” was established as a supplement to the section on concrete for filling steel tubular structures in JASS 5 “Japanese Architectural Standard Specification for Reinforced Concrete Work” of the Architectural Institute of Japan. This “Recommendation” presents the latest knowledge on concrete for filling steel tubular structures and the rational mix design and construction methods existing at the present time. In addition, in consideration of the view that bleeding tests to verify the quality of concrete are complicated to carry out, it proposes ways to rationalize such testing, along with other improvements. This report presents an outline of the above.
