A Nodal Connection Method for Axial Forced Components

Abstract

The invention discloses a node connection method of an axial force-bearing member, which includes adjusting the connection state of the node of the axial force-bearing member, so that the node of the axial force-bearing member can be free movement of the axial direction of the axial force-bearing member; apply the first load and preload on the axial force-bearing member; adjust the connection state at the node of the axial force-bearing member again, so that The node of the axially stressed member is adjusted from the free movement to immovable, the preload on the axially stressed member is removed and a second load is applied. By adopting the method of the present invention, the partial uneven internal force after the final stacking of the axially stressed member can be reduced, thereby effectively homogenizing the internal force of the axially stressed member, which is beneficial to the accurate analysis of the structural feasibility of the axially stressed member , it is also beneficial to the mechanical properties of the axially stressed members in the structure, making the overall mechanical properties of the structure better.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a node connection method of axially stressed members. Background technique [0002] In engineering, the judgment of the structural feasibility and rationality of a component is usually realized by calculating the internal force of the component. Taking the axial force-bearing member as an example, the so-called axial force-bearing member mainly refers to its controlling internal force or main internal force as the axial force, the bending moment is relatively secondary, and generally the accompanying shear force and torque are even more secondary. There are usually two forms of connection of traditional axially stressed members, either hinged (hinged) or fixedly supported (rigidly connected), and then in the case of hinged or fixedly supported axially Based on the full load of the load, the axial force of the axially stressed member is calculated. [0003] In the...

Problems solved by technology

[0003] In the traditional structural technology, the connection of the predetermined axially stressed members is generated once, and its structural load is applied at one time, or the generation of node connections and the application of loads are passively simulated according to the construction steps, resulting in the axial force distribution of the axially stressed members Extremely uneven, this kind of unevenness is likely to cause poor structural deformation performance and economical efficiency, and may even make a wrong judgment that the structure is not feasible
