Problems solved by technology

The bearing capacity of this kind of member is mostly controlled by the bending stiffness, and the concrete in the section close to the centroid cannot provide much bending stiffness, which instead increases the risk of the structure's own weight

Abstract

The invention provides a combined lattice type hollow component. The hollow component comprises an inner steel tube, plural outer steel tubes, inner web members, outer web members, a concrete filling layer and a concrete cladding layer, wherein the outer steel tubes are arranged around the peripheries of the inner steel tube; the inner steel tube is connected with the outer steel tubes through the inner web members; the two adjacent outer steel tubes are connected through the corresponding outer web member; the outer steel tubes are filled with the concrete filling layer; the inner steel tube, the outer steel tubes, the inner web members and the outer web members are cladded int the concrete cladding layer. The combined lattice type hollow component has the light weight, the good integrality, the high bearing capacity, the large flexural rigidity and the good fire resistance.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a combined lattice hollow component. Background technique [0002] The in-plane flexural rigidity of a composite member using a single steel pipe and concrete is low. When the slenderness ratio is large, it is easy to lose stability, and it is difficult to give full play to the material properties of steel pipe and concrete. At this time, lattice members can be used. Lattice members can obtain larger section bending stiffness through smaller-sized limbs, and thus have higher bearing capacity. The webs of lattice members are often made of empty steel pipes or other plates, and their stiffness is relatively limited. When the member undergoes large deflection deformation, the webs will undergo large shear deformation. Conventional lattice member webs and split steel pipes are directly exposed to the outside world, and will soon fail under the action of fire, causing the lattice mem...
