Square-sleeve-round steel tube ultra-high performance concrete column with T-shaped section stiffening ribs
The invention discloses a square-sleeve-round steel tube ultra-high performance concrete column with T-shaped section stiffening ribs. The square-sleeve-round steel tube ultra-high performance concrete column is characterized by comprising an inner steel tube 1, an outer steel tube 2, the T-shaped stiffening ribs 3 and ultra-high performance concrete 4. The inner steel tube and the outer steel tube are square-sleeve-round thin-wall steel tubes and are concentrically arranged, the ultra-high performance concrete is added into an interlayer, and the T-shaped ribs are welded to the inner steel tube so as to be arranged in the concrete. Although the ultra-high performance concrete is high in strength, the brittleness is large, and the T-shaped ribs are arranged to assist the square outer steel tube in better restraining the concrete. The member improves the flexural capacity of the concrete filled steel tube column under the bias pressure condition, so that the ductility of the member is improved, and the member has the advantages of reasonable stress, clear force transmission, high construction speed and the like, and is more suitable for being used in practical engineering.
本发明公开了一种带T形截面加劲肋方套圆钢管超高性能混凝土柱，其特征包括：1、内钢管2、外钢管3、T型加劲肋4、超高性能混凝土。内外钢管为方套圆薄壁钢管，同心放置，夹层加入超高性能混凝土并在内钢管上焊接T型肋使其内置于混凝土中。高强性能混凝土虽强度高，但脆性较大，设置T型肋辅助方形外钢管更好的为混凝土提供约束作用。该构件提高钢管混凝土柱偏压条件下抗弯承载力，使得构件延性增加，具有受力合理，传力明确，施工速度快等优点，更适合在实际工程中使用。
