Abstract

The invention provides a reinforced concrete pipe lattice column comprising at least two hollow pipe columns, wherein each hollow pipe column is at least connected with an adjacent hollow pipe column through a web member; a reinforced concrete column is also coated at the periphery of the hollow pipe column. The pipe lattice column disclosed by the invention is light in dead load, high in bearing capacity, and good in fire resistance; local buckling of the hollow pipe column can be delayed.

Description

technical field

[0001] The invention relates to the field of civil engineering, in particular to a reinforced concrete tubular lattice column. Background technique

[0002] Fiber-reinforced composites (FRP) have the advantages of high strength, light weight, and corrosion resistance, so they are increasingly used in civil engineering. Conventional hollow interlayer FRP pipe concrete is a member formed by pouring concrete between two concentrically placed FRP pipes, which can be used in buildings, bridges and special structures in harsh environments such as oceans and humidity. However, the amount of FRP used in conventional hollow interlayer FRP tube concrete members is relatively large. Once a fire breaks out, the outer FRP tube will soften quickly, and the member will quickly reach the fire resistance limit under a high axial compression ratio. Therefore, under certain conditions, it is necessary to The outer surface of the hollow interlayer FRP pipe concrete is painted w...
