Problems solved by technology
When the torsion member is under the action of load, especially when the load is asymmetrically distributed, the internal force on each support is often inconsistent, and the distribution of internal force and torque is very uneven, which makes the mechanical performance of the torsion member in the structural design poor, and reduces the load.

The invention relates to the technical field of structural engineering, and particularly discloses a pre-internal force of a torsion member and a calculation method thereof, comprising the following steps: calculating all loads borne by the torsion member when a support of the torsion member is in an original connection state, and adjusting a first support with larger internal force from the original connection state to a first connection state; keeping the second support with smaller internal force unchanged or increasing constraints for reinforcement, applying a preload to the torsion member, adjusting the first support from the first connection state to the second connection state, removing the preload applied to the torsion member, and applying all loads to the torsion member; and respectively calculating internal forces of the two supports based on the two different states of the two supports, and superposing the internal forces to obtain target internal forces of the two supports. Pre-internal force is generated on the torsion member by applying and removing the pre-load, so that the non-uniformity degree of all loads on the internal force of the torsion member can be effectively reduced, the stress of the torsion member achieves a more uniform and ideal effect, and the use effect of the torsion member in the structure is improved.
Description
technical field [0001] The invention relates to the technical field of structural engineering, in particular to a pre-internal force of a torsion member and a calculation method thereof. Background technique [0002] In traditional structures, the support connections of torsion members are generally fixed at both ends. When the torsion member is under the action of load, especially when the load is asymmetrically distributed, the internal force on each support is often inconsistent, and the distribution of internal force and torque is very uneven, which makes the mechanical performance of the torsion member in the structural design poor, and reduces the load. Effects of using torsion members in structures. Contents of the invention [0003] The invention discloses a pre-internal force of a torsion member and a calculation method thereof. By connecting the supports of the torsion member in stages, and applying and removing the preload at different stages, the uneven intern...
