Loading and internal force calculation method of axis stress component

Abstract

The invention discloses a loading and internal force calculation method for an axis stress component. The method comprises steps of adjusting the connection state of a node of the axis stress component to be a second connection state, and calculating the total load to be borne by the axis stress component in the second connection state; adjusting a connection state of the node of the axis stress component from a second connection state to the first connection state, and applying a first load; the connection state of the joint of the axis stress component being adjusted from the first connection state to the second connection state again, and a second load being applied; calculating the internal force of the axis stress component under the action of the first load based on the first load, calculating the internal force of the axis stress component under the action of the second load based on the second load, and superposing the internal forces to obtain the target internal force of theaxis stress component. By the adoption of the method, the axial force borne by the axis stress component can be effectively reduced and homogenized, and then the stress performance and economical efficiency of the axis stress component are improved.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to a method for calculating the loading and internal force of an axially stressed member. Background technique [0002] In engineering, the judgment of structural feasibility and mechanical performance is usually realized by calculating the internal force of structural components. Taking the axial force member as an example, the so-called axial force member mainly refers to the structural member whose controlling internal force or main internal force is the axial force, the bending moment is relatively minor, and generally accompanied by shear force, torque, etc. There are usually two forms of node connection of traditional axially stressed members, either hinged (or hinged) or fixed (or rigidly connected), and then hinged or fixedly supported on axially stressed members In the case of , the full load it bears is loaded, and the axial force of the axially stressed member is ca...

AI Technical Summary

Problems solved by technology

Regardless of hinged support (or hinged connection) or fixed support (or rigid connection), the structural members whose joint stiffness is directly generated at one time, the axial force generated under the load is often unevenly distributed or even extremely uneven in the structure. As a result, the standardization of structural components is low, the project cost is high, technical measures are difficult, and even the structure is difficult to realize
