Section steel flange-weakened recycled concrete earthquake-resistant energy-consuming composite column and production method thereof
The invention discloses a section steel flange-weakened recycled concrete earthquake-resistant energy-consuming composite column. The section steel flange-weakened recycled concrete earthquake-resistant energy-consuming composite column comprises section steel web plates, longitudinal bars arranged parallel to the section steel web plates, stirrups arranged along the length directions of the longitudinal bars, concrete filled thereamong, and section steel web plate weakened flanges located in the middle area of the composite column, wherein the concrete is recycled aggregate concrete, and the replacement rate of waste concrete aggregates is 45-55%. In the section steel flange-weakened recycled concrete earthquake-resistant energy-consuming composite column disclosed by the invention, due to the weakening of the section steel flanges in the middle area of the column, the column is fully used, the column has good rigidity and ductility under the effect of an earthquake load, and the energy-consuming capacity of column members and the safety of a structure are improved; and due to the weakening of the section steel flanges in the middle area of the column, compact pouring for the concrete of the column is effectively improved, and the construction quality is improved.
