Latticed columns are used as bending and compression members, and they are mostly used in frame columns and independent columns of power houses. The cross-section is usually steel or steel plate, and the cross-section is designed as biaxial symmetry or uniaxial symmetry. The members of the lattice system are composed of limbs and battens. The limbs mainly bear the axial force, and the battens mainly resist the lateral forces (relative to the axial direction of the limbs). The forms of the batten are mainly battens and battens.

The structural feature of lattice column is that the material area is arranged far away from the inertial axis, which can ensure the bending performance of the component under the same axial resistance condition and save materials.
