摘要
为研究L形截面宽肢混凝土柱的抗剪性能,对反复加载的8根试件进行了试验研究,重点研究了宽肢L形混凝土柱的破坏形态,并提出加载角度、截面肢高肢厚比和有无暗柱的设置是影响L形截面宽肢混凝土柱性能的主要因素.
On the basis of the experimental research on wide flange L-shaped section columns with different flange width/thickness ratios,the effects of flange width/thickness ratio and different loading angle on the failure mode are studied primarily.The following conclusion can be drawn: for the performance of L-shaped section columns,flange width/thickness ratio,different loading angle and effect of embedded column are major factors.
