Background
Steel lattice columns and lattice beams are structural members commonly used in engineering. Lattice beams and columns are typically made up of limbs and lacing material. The limb and the lacing material can be selected from angle steel, I-shaped steel, steel pipes and the like. The sectional materials can be selected from national standard models, raw materials are easy to purchase, meanwhile, the rod piece is usually small in size, and the on-site processing is convenient and rapid. The lattice component can ensure that the bending resistance of the component is stronger under the same axial resistance condition by arranging the material area far away from the inertia shaft, and saves materials. The steel lattice column and the lattice beam have the advantages, and the application range is enlarged year by year.
Steel lattice columns and lattice beams are generally used for plant columns, independent columns and independent beams, and are rarely applied to multi-layer frame structures with seismic fortification requirements. In a multi-layer frame with the requirement of seismic fortification, a node area where a frame column and a frame beam are intersected can bear larger shearing force. The lattice component is far from the center due to the arrangement of materials, so that the compression resistance and the bending resistance of the component are both strong, but the shearing resistance is weak, and the horizontal force resistance is weak. This results in a very limited use of the lattice structure in multi-layer frames with seismic requirements.
