［摘要］某高层超限项目的钢管混凝土组合柱-钢筋混凝土梁节点采用大开孔贯通型连接方式，由于梁之间夹角较小造成钢管壁上开孔密集，且孔距较小，易出现不利的应力集中现象。通过采取必要的补强措施以保证节点抗震性能是节点设计的关键问题。有限元计算分析表明，通过在钢管壁上设置合理的竖向加劲板和环向加劲板，钢管混凝土组合柱节点能够满足预期的抗震性能目标。

Abstract: Through type joints of concrete-filled steel tublar composite column and RC beam  with large openings are applied in the design for an out of code high-rise building. Because of the small intersection angles between RC beams, the openings on the wall of steel tubes are concentrated, and the spacing between openings is small, therefore the stress concentration is prone to appear. It is the key point during the joints design to take some necessary strengthening measures to ensure the seismic behavior of such joints. Finite element analysis results demonstrate that the seismic behavior of the joints with large openings can achieve the desired performance target by applying rational vertical and circumferential stiffening plates on the wall of steel tubes.

Keywords: concrete-filled steel tublar composite column; through type joint with large opening; seismic behavior; finite element analysis
