Prestressed pull rod foundation design method for large-span space structure

Abstract

The invention relates to a prestressed pull rod foundation design for a large-span space structure, belonging to the field of civil engineering. A prestressed pull rod 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 design method for a prestressed tie rod foundation in a large-span space structure. Background technique [0002] At present, in the large-span spatial structure engineering, the design method of separating the superstructure, foundation and foundation is still widely used. In fact, any building is composed of these three parts. As a whole, these three parts work together, are interrelated and affect each other. The design and calculation of the three are separated from the actual working conditions, which will inevitably cause large errors. [0003] The joint action of the superstructure and the foundation is to regard the superstructure, foundation and foundation (pile foundation including piles) as a whole. While satisfying the static balance conditions, the foundation, foundation and superstructure must also be satisfied. Deformation coordination conditions for con...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a design method for the prestressed tie rod foundation in a large-span spatial structure, which solves the problem that the current design method does not fully consider the superstructure and foundation of the large-span spatial structure during construction, normal use, and bearing capacity. There is no detailed distinction between the structural analysis models and calculation methods at different stages, resulting in the fact that the normal use and ultimate bearing capacity of the actual prestressed tie rod foundation cannot meet the structural requirements, which brings safety hazards to the project.
