Embodiment Construction

[0031] A parametric forward BIM design method for bridge components, comprising the following steps:

[0032] 1. To quickly construct a parametric solid BIM model of three-dimensional components, it is necessary to determine parameters such as LCSS, LCES, TLHLi, TTHLi, TAHLi, TFOSi, TTFij, TPi, BLHLi, BTHLi, BAHLi, BFOSi, BTFij, BPi, H, TTi, BTi, etc. See below for details:

[0033]Step 1: Read road engineering line information such as road design horizontal curves, vertical (longitudinal) curves, and side lines to determine road design three-dimensional control lines, mileage stakes, expansion joints, bearings, etc., and the left and right lines of the top plate of bridge components.

[0034] Step 2: Use the intersection point of the small mileage stake number at the beginning of the bridge member and the design horizontal curve of the road, and name it: LCSP, and determine the parameters LCSS and LCES for the position of the beginning and end of the broken line of the member...

Abstract

The invention discloses a parameterized forward BIM design method for a bridge component. The method comprises the following steps of: inputting road line information data and determining design parameters of the bridge component, and providing a model for rapidly constructing a three-dimensional component parameterized entity BIM (Building Information Modeling for short) for bridge component design software. The three-dimensional component parameterized entity BIM model obtains a construction drawing, a calculation book and a BIM model of the bridge component through one of the following two paths, path 1: bridge component design information data are inputted and then imported into a structure analysis system, stress analysis is met, and checking calculation is carried out according to relevant specifications of the bridge; and path 2: a structure analysis system is imported, meeting stress analysis, and automatic design of a program after checking calculation according to relevant specifications of the bridge are met. According to the method, the construction drawing, the calculation book and the BIM model of the bridge component can be rapidly designed, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of forward BIM (Building Information Modeling, hereinafter referred to as: BIM) design of bridge components, and in particular relates to a parametric forward BIM design method of bridge components.
