Abstract

The invention discloses a pre-stressed continuous concrete beam design method based on the BIM technology. The pre-stressed continuous concrete beam design method includes the following steps that according to a file format, pre-stressed continuous beam design information is input; a finite element model is formed, and the structure size is analyzed and determined through the numerical value; an information-model parameterization cross section library is built; according to the structure size, a cross section is automatically instantiated to generate a continuous beam three-dimensional model containing user information; according to the characteristics of the cross section of the continuous beam, a reinforcing-steel-bar-net space node coordinate database is automatically built; instantiation data is sequentially comprises all parts of arrangement space reinforcing steel bars of the continuous beam, and user information is added; according to an information module, two-dimensional drawings are automatically established, quantity statistics is automatically completed. By means of the pre-stressed continuous concrete beam design method based on the BIM technology, rapid forming of universal data, the three-dimensional information model and the reinforcing-steel-bar drawings is achieved, and the pre-stressed continuous concrete beam design method has good popularization value and the good application value.

Description

technical field [0001] The invention belongs to a design method of a prestressed concrete continuous beam, in particular to a design method of a prestressed concrete continuous beam based on BIM technology. Background technique [0002] In bridge construction, prestressed concrete continuous beams account for a large proportion, which puts forward higher requirements for the design quality and efficiency of continuous beams. However, the traditional two-dimensional design of prestressed concrete continuous beams has repeated data input, and the calculation of basic data and structural design The basic data is not universal; the spatial relationship is scattered, and the concrete structure, prestressed beams, steel bars, and embedded parts are scattered in different two-dimensional plans; non-parametric, and information linkage between design parameters cannot be realized. Contents of the invention [0003] The present invention is proposed to solve the problems existing in...
