高层建筑结构设计中改善短柱抗震性能的方法
|
摘要
短柱的剪切破坏往往是造成钢筋混凝土框架破坏甚至倒塌的主要原因,正确判断和处理短柱是结构设计时需面对的问题。当短柱出现时,可采用高强混凝土、框架-抗震墙结构体系、复合箍、复合螺旋箍、钢骨混凝土柱等综合技术措施,以消除短柱或改善短柱的抗震性能。
Shear failure of short columns is often the main cause of failure or even collapse of reinforced concrete frame and judging and handling short columns correctly are therefore what have to be faced in the design. If short column is used comprehensive technical measures such as high strength concrete frame anti-seismic wall system composite hoop compound spiral hoop and steel framed concrete column etc. may be taken to eliminate short column or improve its anti-seismic performance.
