壁板とスラブの交差部にもスラブと同じ低強度のコンクリートを打設したRC 耐震壁の水平加力実験を2シリーズ実施した。シリーズⅠではスラブの位置、スラブ筋量および低強度層の厚さを、シリーズⅡではスラブの有無をパラメータとした。スラブのある低強度層の破壊は見られず、壁板のコンクリート強度を用いて計算したせん断耐力を最大水平荷重が上回った。低強度層の圧縮側端部のスラブ筋に生じたひずみを用いて側圧を算出し、三軸部分圧縮時のコンクリート強度算定理論から低強度層の等価圧縮強度を算定した。その結果、等価圧縮強度計算値が壁板のコンクリート強度と同程度となった。 キーワード: 耐震壁、壁板、スラブ、拘束、側圧、圧縮強度 |

Shear loading tests of wall panel having wall-slab panel joint region whose concrete strength was the same as slab were conducted. The test parameters of series 1 were the height and reinforcement quantity of slab, and the thickness of wall-slab panel joint, and those of series 2 were the presence or absence of the slab. Any damage was not observed at the wall-slab panel joints. The maximum loads exceeded the ultimate shear strength calculated using the compressive strength of wall panel. The equivalent compressive strength was calculated by the lateral pressure which were calculated by strain of the slab reinforcements arranged at the end of the wall panel under the theory of triaxial partial compressive strength. In consequence, the calculated equivalent compressive strength was nearly equal to the compressive strength of wall panel.
