Problems solved by technology

For the secondary internal force structure (that is, the secondary internal force that is perpendicular to the direction of the load under the load), the secondary internal force generated under the load is relatively large, which leads to poor mechanical performance of the structural members, and the material Underperformance

Abstract

The invention discloses a pre-internal force of a secondary internal force structure and a calculation method thereof. The secondary internal force structure comprises a first component and a second component, the first component comprises a first joint and a second joint, and the method comprises the steps that the connection state of the second component and the first joint and / or the second joint of the first component is adjusted, so that the second component and the first node and / or the second node form a first connection state, and a preload is applied to the first component; internal force of each node of the first component is calculated according to the applied preload; the method also includes adjusting the connection state of the second component and the first node and / or the second node of the first component to be a second connection state, removing the preload on the first component, and applying a load on the first component; based on the unloading preload and the applied load, respectively calculating the internal force of each node of the first component; performing superposition of the internal forces. By the adoption of the method, secondary internal force generated by the first component can be effectively reduced, and meanwhile distribution of main control internal force of the first component is homogenized.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a pre-internal force of a secondary internal force structure and a calculation method thereof. Background technique [0002] At present, when analyzing the stress of structural members, the state of its nodes is usually generated into a single state at one time, and the structural member bears the full load in this single state. In this way, some internal forces generated by structural members under load tend to be large. For the secondary internal force structure (that is, the secondary internal force that is perpendicular to the direction of the load under the load), the secondary internal force generated under the load is relatively large, which leads to poor mechanical performance of the structural members, and the material Inadequate performance. Contents of the invention [0003] The embodiment of the invention discloses a pre-internal force of a secondar...
