The beams carry the entire weight of the components and roofing in the building superstructure, the most important part of the building superstructure. The names are different depending on the specific location, detailed shape, specific action, etc. of the beam. Most beams are oriented to conform to the cross section of the building.
Beams are members that are subjected to vertical loads, primarily in bending. The beams are generally horizontally arranged and are used for supporting the plates and bearing various vertical loads transmitted by the plates and the dead weight of the beams, and the beams and the plates form a floor and roof structure of the building together. Compared with other transverse stress structures (such as trusses, arches and the like), the beam has poorer stress performance, but has simple analysis and convenient manufacture, so the beam is widely applied to medium-and small-span buildings. The beams are subjected to mainly bending moments and shearing forces, and sometimes also to torsion forces, under load.
Beams are components that are often found in building structures. In the frame structure, the beams connect columns in all directions into a whole; in the wall structure, the connecting beam above the opening connects two wall limbs to make them work together. As an important component of the earthquake-proof design, plays a role of a first line of defense. In a frame-shear wall structure, the beams function as in both the frame structure and the shear wall structure.
