REINFORCEMENT STRUCTURE OF COLUMN-BEAM CONNECTION PORTION
To improve earthquake performance of a building by improving shearing strength of a beam-column connection portion 10 and by holding bending strength of an upper reinforced concrete column 14A and a lower reinforced concrete column 14B.SOLUTION: A beam-column connection portion 10 is restricted by a surrounding plate 20, and, separately from the beam-column connection portion 10, a lower end of an upper reinforced concrete column 14A and an upper end of a lower reinforced concrete column 14B are restricted by an upper band plate 22A and a lower band plate 22B. That is, the beam-column connection portion 10 and end portions of the reinforced concrete columns 14 connected with the beam-column connection portion 10 are separately restricted by the surrounding plate 20 and the upper and lower band plates 22A,22B separated from the surrounding plate 20.SELECTED DRAWING: Figure 1
【課題】柱梁接合部１０のせん断耐力を向上させ、同時に、上鉄筋コンクリート柱１４Ａと下鉄筋コンクリート柱１４Ｂの曲げ耐力を保持させ、建物の耐震性能を高めること。【解決手段】柱梁接合部１０を囲み板２０で拘束し、かつ、柱梁接合部１０と切り離して上鉄筋コンクリート柱１４Ａの下端と、下鉄筋コンクリート柱１４Ｂの上端とを上バンドプレート２２Ａと下バンドプレート２２Ｂとで拘束するようにした。すなわち、柱梁接合部１０と、この柱梁接合部１０に連結される鉄筋コンクリート柱１４の端部とを、囲み板２０と、この囲み板２０と切り離された上下のバンドプレート２２Ａ、２２Ｂで別々に拘束するようにした。【選択図】図１
