摘要
肢长厚比大于 4的 9根不等肢L形截面和 3根不对称T形截面短肢墙的偏心受压破坏试验结果显示 ,截面变形基本上符合平截面假设 ,中和轴不垂直于弯矩作用平面 ,中和轴位置随荷载的增大而变化。在正截面承载力计算图式中 ,采用混凝土受压区等效矩形应力分布图 。
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.
