型钢混凝土柱中钢柱翼缘开孔分析

在实际工程中,特别是在高层和超高层结构中,型钢混凝土柱截面尺寸往往相对于钢筋混凝土梁要大得多,有时柱中型钢翼缘甚至比混凝土梁要宽得多,这就无法满足钢翼缘不开孔的要求。本文以实际工程中存在的混凝土梁—型钢混凝土柱的节点为研究对象,推导了型钢混凝土柱的缺损率公式,同时研究钢柱翼缘开孔大小、孔间距、孔边距等参数对型钢混凝土柱中的钢柱翼缘应力分布的影响,最后,对工程中常用的开孔翼缘补强方法进行分析,得出了补强板的最优板厚。

Analysis of steel column wing with hole in SRC column

In practical engineering,especially in high-rise and super high-rise structure,the section of SRC column is often much bigger than RC beam,even sometimes width of RC beam cross section is often even smaller than width of steel wing of SRC steel column.If wing of section steel column not have hole,it is difficuly to solve reinforcing bars go through node of beam-column directly,this paper study on node of RC beam-SRC column which is often exist in practic engineering,deduced section steel colomn defect rate formula,study on parameter which is size of hole,distant of between hole and hole and edge of steel column,having effect on distribute of stress of wing.At last carrying out study on reinforced method of steel column wing with hole,having reached the optimum thick of reinforcing board.
