Background
Under the national macro regulation, the steel structure industry is developing hot flashes, and the study of steel structure houses is becoming more and more intensive. In a traditional steel frame structure house, the lateral rigidity of a frame column is often insufficient due to the limitation of the cross section size, the increase of the cross section size can cause the increase of the manufacturing cost, meanwhile, along with the variability of the shape of the shear wall, the concrete frame structure can avoid the protrusion of indoor column feet, so that the beautiful appearance of the building is greatly improved, the building space is increased, the indoor arrangement is more flexible, and the convenience is brought to the architectural decoration design. The appearance of the multi-limb special-shaped lattice column improves the defects of the steel structure in terms of attractive appearance and space utilization compared with a concrete structure to a great extent, so that the steel structure house reaches the same level as the concrete house in terms of use function and even exceeds the steel structure house. The steel structure is formed by connecting a plurality of limbs with smaller section size, so that the bending rigidity is high, and the steel structure has excellent anti-seismic performance, so that the anti-seismic performance of the multi-limb special-shaped lattice column steel frame structure is more excellent.
At present, a plurality of multi-limb lattice columns are mostly applied to single-layer and higher-layer industrial plants, steel pipe concrete arch bridges and the like, and are rarely applied to multiple high layers, and the main reason is that the multi-limb lattice columns are relatively complex in force transmission among all column limbs, wherein at least one column limb is required to be connected with other column limbs in multiple directions through a binding material, the section form of the column limb is required to be a square rectangle, so that the multi-limb special-shaped lattice column and steel beams are relatively complex in combination, and a reliable and simple-mature-process connection mode is also lacking at present, so that the multi-limb special-shaped lattice column is relatively less applied to middle and high layers, and the development of steel structure houses is greatly restricted.
