The difference between tension bending and compression bending members of steel structure workshop
The difference between tension-bending and compression-bending members of steel structure workshops is as follows: tension-bending members refer to members that additionally bear the effects of radial tensile force and bending moment, and arched pavement not only bears the resistance of the two carrying legs, but also bears the longitudinal load of the pavement , is a typical bending member;Compression-bending members are mostly found in beams and column members in architecture and portal steel frame structures, so they are often called column-beams. In addition, the variable cross-section columns often used in single-sided factory buildings are compression-bending members with very complex structures.
The support of the tension-bending member includes the member that is subjected to the axial force tensile force function and the tension member that has the lateral load function in the middle.
There are many load functions of compression-bending members, including the member bearing the axial force working pressure, the member receiving the lateral load effect or the lateral multi-centralized load effect, and bearing the bending moment transmitted from other members. In specific applications, it will also be used. The accumulation of various load effect modes occurs.
For tension-bending members and compression-bending members with a large axial force and a small bending moment, biaxially symmetrical sections are generally used. When the size is very large, electric welding is generally used to form a solid-web uniaxial symmetrical cross-section. When the length of the bending member is large and the bending moment is also large, in order to save stainless steel plates, the uniaxially symmetrical lattice member is also used.
