Prestressed cable foundation design method for large-span space structure

Abstract

The invention relates to a prestressed cable foundation design for a large-span space structure, belonging to the field of civil engineering. A prestressed cable foundation design method for the large-span space structure is disclosed by the invention, which changes the current situation that the foundation and upper part of the current large-span space structure are designed separately, establishes a simplified design method for the prestressed concrete foundation tie beam of the large-span space structure in consideration of the interaction between the upper structure and the foundation, fills in the blank in the foundation design of the large-span space structure, and develops an interaction analysis method for the foundation and the upper structure of the large-span space structure. Based on this, the designed structure fully considers the mutual mechanism between the upper structure and the foundation of the large-span space structure in each stage of construction, normal usage and bearing, and also distinguishes the structure analysis model and calculation method in different stages in detail so as to meet the requirement of the practical structure more and have better safety performance.

Description

Technical field [0001] The invention relates to the field of civil engineering design, in particular to a method for designing a prestressed cable foundation in a large-span space structure. Background technique [0002] At present, in large-span space structure engineering, the design method of separating the superstructure, foundation and foundation is still generally adopted. In fact, any building is composed of these three parts. As a whole, these three parts work together, interconnect and influence each other. Separating the three to design and calculation is different from the actual working conditions, which will inevitably cause large errors. [0003] The superstructure and the foundation work together to treat the superstructure, the foundation and the foundation (pile foundation including piles) as a whole. While satisfying the static balance conditions, it also satisfies the foundation, foundation and superstructure. Deformation coordination conditions of contact part...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a design method for the prestressed cable foundation in a large-span space structure, which solves the problem that the current design method does not fully consider the superstructure and The mutual mechanism between the foundations, and the structural analysis models and calculation methods of different stages are not distinguished in detail, resulting in the fact that the normal use and ultimate bearing capacity of the actual prestressed cable foundation cannot meet the structural requirements, and bring safety hazards to the project.
