Topology Research Of Structure BIM Model System With High Level Of Detail

Building Information Modeling is the way to realize data sharing and cooperative working between the participant by using the same multidimensional information model.It will change the work model of engineering survey and design industry.Structure engineer should use the very detail structure information,such as the constructional information or the reinforcement information,to continually structural analysis or simulate.It is the guarantee of producing the real value of using BIM in the structural engineering field that the structure BIM model with high level of detail has very excellent ability of information changing.At present,there still are many problems during the BIM modeling,like randomness,heavy workload,inefficient,hardily controlling the quality of modeling.This phenomenon not only produces the assignable difficult to use structure BIM but also cause hardily modeling the correct BIM model to realize the intelligent information integrated in the future.In order to solve such difficult,this article,based on the Theory of Communication,Topology theory and Artificial Neural Electromagnetic Field,systematically research the configuration of using BIM in the structure engineering field,the method of high efficiently modeling the BIM model with high level of detail,the method of quantificationally controlling the quality of modeling and the intelligent way to obtain information from the BIM model.First,this article explores the quantificational research model by analyzing the literature and several BIM projects in real,get the key point of researching the structure BIM with high level of detail.Second,recognize the element of implementing the structure BIM and define the configuration of these elements,called “Structure BIM Configuration” based on the topology space theory.Third,pick out the sample,the sub model of 50 m precast box beam with high level of detail,research the key element “Structure BIM Model System” by topological experiment,get the information topological structure of structure BIM model system,put forward the method to evaluate the quality of BIM model.Finally,simplify the information topology structure and establish the mathematical model of two typical nodes in the topological structure network,get the network node model.All of conclusion of preview work are used in the real structure project,analyze and review this work.This work establishes the “Structure BIM Configuration” which can describe the way of configuring the structure BIM model system.In the model experiment,find the information topology structure in structure BIM model system and the property,resembling cellular fission,of BIM information topology structure by changing the capacity of sub models,put forward the way to evaluate the quality of BIM model,establish the network node model of structure BIM model system and realize directly using structure BIM model with a high level of detail in structural analysis and simulation.,and hope this work can provide the reference to research the big data of building in the future.
