[提要]  肢長(zhǎng)厚比大于4的9根不等肢L形截面和3根不對(duì)稱T形截面短肢墻的偏心受壓破壞試驗(yàn)結(jié)果顯示，截面變形基本上符合平截面假設(shè)，中和軸不垂直于彎矩作用平面，中和軸位置隨荷載的增大而變化。在正截面承載力計(jì)算圖式中，采用混凝土受壓區(qū)等效矩形應(yīng)力分布圖，極限荷載計(jì)算值與試驗(yàn)結(jié)果符合較好。

The experimental research on reinforced concrete short-limb wall is reported. The experimental results of 9 inequilateral L-section specimens and 3 unsymmetrical T-section specimens show that the Bernoulli's principle holds for the specimens, the neutral axis is not perpendicular to the plane that the moment acts on and the position of the neutral axis varies with the increasing of load. If equivalent rectangular stress block in the compression zone is applied in the analysis of carrying capacity, the calculating ultimate loads agree with the testing results well.
Keywords: reinforced concrete; short-limb wall; bidirectional eccentric compression
