［摘要］某高層超限項目的鋼管混凝土組合柱-鋼筋混凝土梁節(jié)點采用大開孔貫通型連接方式，由于梁之間夾角較小造成鋼管壁上開孔密集，且孔距較小，易出現(xiàn)不利的應力集中現(xiàn)象。通過采取必要的補強措施以保證節(jié)點抗震性能是節(jié)點設計的關鍵問題。有限元計算分析表明，通過在鋼管壁上設置合理的豎向加勁板和環(huán)向加勁板，鋼管混凝土組合柱節(jié)點能夠滿足預期的抗震性能目標。

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
