FRP (Fiber Reinforce Plastic) pipe constraint type steel rubber concrete column and preparation method thereof

The invention relates to the field of structural engineering and sustainable concrete, and discloses an FRP pipe restrained section steel rubber concrete composite column which comprises an FRP pipe, rubber concrete and section steel, the section steel is arranged in the FRP pipe, and the space between the section steel and the FRP pipe is filled with the rubber concrete. And the threat of stacking of the waste tires to the life and the ecological environment of people is reduced. The rubber powder obtained by grinding the waste tires is used for replacing natural river sand, so that the demand quantity of the natural river sand is reduced, and the influence of excessive exploitation of the natural river sand on the ecological environment is reduced. By adopting an optimized substitution mode and a modification mode, the mechanical property of the rubber concrete can be improved, so that the rubber concrete can be used as a main bearing component, and the application of the rubber concrete in practical engine
