DESIGN METHOD OF STEEL-FRAME THROUGH HOLE, AND STEEL-FRAME WITH THROUGH HOLE
PROBLEM TO BE SOLVED: To provide a technique which maintain strength of a steel bar, and make a through hole aperture of a web of a steel-frame smaller than before.SOLUTION: A design method of a steel-frame through hole in a web of a steel-frame of a steel-framed reinforced concrete structure comprises: an original design processing in which a through hole aperture of the steel-frame is obtained based on outer diameters of two steel bars that are lapped and inserted into the through hole of the steel-frame, and the cross sectional areas of the steel bars are obtained; and a correction processing in which at least one of the steel bars inserted into the through hole of the steel-frame is bundled as a bundled bar bundling a plurality of steel bars, and the through hole aperture is designed so that the sum of the cross-sectional areas of the bundled bar is not less than the cross sectional area obtained in the original design processing, and so that the through hole aperture of the steel-frame is smaller than the aperture obtained by the original design processing.SELECTED DRAWING: Figure 3
【課題】鉄筋の強度を維持し、鉄骨のウェブの貫通孔の孔径を従来よりも小さくする技術を提供する。【解決手段】鉄骨鉄筋コンクリート構造物の鉄骨のウェブに設ける鉄骨の貫通孔の設計方法であって、前記鉄骨の貫通孔にラップして通す２本の鉄筋の外径に基づいて当該鉄骨の貫通孔の孔径を取得し、かつ、前記鉄筋の断面積を取得する原設計処理と、前記鉄骨の貫通孔に通す鉄筋のうち少なくとも一本の鉄筋を複数の鉄筋を束ねた束ね筋とし、当該束ね筋の断面積の和が、原設計処理で取得した鉄筋の断面積を下回らず、かつ、前記鉄骨の貫通孔の孔径が原設計処理で取得した孔径よりも小さくなるように孔径を設計する修正処理と、を含む。【選択図】図３
