Computer-aided design method for outer closed stirrup of concrete bridge strip-shaped component

Abstract

The invention discloses a computer-aided design method for an external closed stirrup of a concrete bridge strip-shaped component a plurality of continuously intersected component surfaces capable offorming a closed space graph are selected as selected surface groups for design in a BIM (Building Information Modeling) of the concrete bridge component based on a Dasso CATIA (Computer-aided Three-dimensional Interactive Application) software environment. The method comprises the following steps: firstly, selecting a reinforcing steel bar reference surface group, a reference line segment of a first closed stirrup in a configuration direction, a reference line segment of a tail end hook position, an initial auxiliary reinforcing steel bar surface and a reference auxiliary reinforcing steel bar plane; then, solving a closed stirrup datum line segment group by utilizing an intersection function in CATIA, and obtaining a center line of a first closed stirrup; solving the arrangement range ofthe closed stirrups and the number of the intervals of the closed stirrups; and finally, building a template for arranging closed stirrups in a certain direction on the surface of the concrete bridgecomponent in batches. By the application of the method, the closed stirrup model group in a certain direction can be quickly established on the surface of the concrete member.

Description

technical field [0001] The invention relates to the technical field of computer-aided design of concrete bridge components, in particular to a computer-aided design method for external closed stirrups of concrete bridge strip components. Background technique [0002] In the current BIM design software, there is a concrete component reinforcement modeling function for civil building structures, which can generate reinforcement models in batches for conventional components such as beams, slabs, and columns; there is also a concrete component reinforcement modeling function for small hydraulic structures. It can generate reinforcement models in batches for some simple shaped components. [0003] However, due to the differences in design methods and habits of civil building structures, hydraulic structures, and bridge structures, the above-mentioned related reinforcement modeling functions are not applicable. [0004] When bridge designers use the current BIM design software to...

Problems solved by technology

[0005] Although the above method can achieve the goal of modeling, it is time-consuming, laborious, and error-prone, which obviously cannot meet the needs of designers for rapid modeling

[0006] Moreover, due to the special structure of the external closed stirrups of concrete bridge strip members, there is no related rapid modeling method
