Problems solved by technology

ANN provides an optimization algorithm but the results are limited to the optimal percentage of the reinforcement design in an RC member, and cannot go on to calculate the details of the reinforcement design (for example, the number and diameter of reinforcement), so it cannot be used on the construction site
In addition, the above methods cannot automate the input data (including load conditions, support conditions and geometric information of RC members)

Abstract

The invention discloses a design system for a reinforced concrete beam based on a building information model (BIM). The system comprises an extraction module, a structure analysis module, a calculation module and an optimization module, wherein the extraction module is used for extracting BIM information needed for rebar design from the BIM, and the BIM information comprises load information, terminal support information and geometric information of the reinforced concrete beam; the structure analysis module is used for calculating a bending moment and shear force exerted on the reinforced concrete beam according to the BIM information; the calculation module is used for converting the geometric information, the bending moment and the shear force into rebar design requirements needed for reinforced concrete beam design according to design specification requirements; and the optimization module is used for optimizing the rebar design requirements by use of a hybrid genetic algorithm according to the design specification requirements. Rebar selection and arrangement provided through the system meet both the design specification requirements and the rapidity, economy and full-automation requirements in the realization process.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete structure design, in particular to a design method and system for a reinforced concrete beam based on a building information model. Background technique [0002] In the structural design of reinforced concrete (RC), reinforcement design is an important aspect. The reinforcement provided in RC members should be able to withstand the design loads imposed on it while being constructible and safe and economical. In a typical RC structural frame, beams, slabs and columns are the most basic and commonly used types of structural members. Among them, beam design is the basic process of structural frame design, and the design process of slab and column is the extension of beam design process. Therefore, the structural design of the RC beam is very important to realize the structural design of the whole RC. [0003] Design specifications for the structural design of RC beams can be achieved w...
