Research On The Simulation Technology Of Steel Structure Engineering

With the rapid development of steel structure construction technology, designtechnology, machining technology, is bound to follow the development of thecorresponding. Compared with reinforced concrete construction, steel structureconstruction; process design institute out map-processing factory-site construction,steel members are mostly in the production processing workshop into. And theconcrete construction design institute is a map of field according to the drawings, theforming process of steel structure construction increased by members of the link inmanufacturing factory.Generally, the design institute drawings cannot be directly used to makecomponents, the need for two design, simple said that according to the blueprint ofdesigning institute in accordance with the actual layout do material drawing, includingnode detail of the steel columns, steel beams, purlins support, etc., to mark the size ofeach material, plate thickness, punch position, the workshop production workersaccording to the processing production material figure two design, otherwise only inaccordance with the Design Institute of the blueprint is unable to carry out theproduction of materials.Therefore, the research of design drawings and processing drawings and siteaccording to technical docking between graph construction, can conveniently realizethe design intent.On the steel structure of the three-dimensional solid modeling and the later detaildeepening design using3D technology, it is in fact the actual construction process ofthe preview, build the basic equal to the actual building. Steel structure BIM modelcontains the entire project node, component, material information. The late countquantity can be directly exported steel consumption, node with a list the number ofbolts and other materials, so that the engineering cost is stick out a mile. Secondly, youcan automatically generate including component diagram, node graph and allconstruction details using3D projection. Due to the geometrical parameters of all drawings are direct projection using three-dimensional entity model is generated, sobasically does not produce error.Design blueprint beyond traditional straight guide steel structure fabrication andassembly site location, then we need to3D software professional to detail deepening.The traditional design process does not take into account the problem betweenprofessional cross each other, the construction site conditions, thus causing more fault,leakage, touch, lack of. BIM model is the traditional2D drawings into3D entity model,according to the information of root actually read easy to determine whether the node,component is arranged in the model is not reasonable place and the construction sitecan be achieved if exists. BIM modeling is actually a virtual construction, and theconstruction of basic no difference. The problems during the construction drawingsand the problems existing in the virtual construction may be encountered in the modeof settlement, which later actual construction becomes smooth and economy.The3D technology detail deepening process can be roughly divided into thefollowing three stages based on. The first stage: the arrangement of axis, according tothe section type and geometric parameters to build3D solid model. The second stage:according to the design blueprint and combination of factories, the site and buildingconstruction related conditions for the processing and installation of treatment on thestructure of node structure. The third stage: to build3D solid models are "collisionchecking, design error checking for the presence of the model, and on the basis ofwritten reports submitted by the collision, modified design personnel to verify. Dueto the dynamic process control, so that each of the above stages have been checkingmore accurate. The main meaning of this research is, through the steel structureprocessing of3D design and construction simulation study, improve the manufactureand construction of the work efficiency, reduce the cost, promote the development ofenterprises and the progress of the industry...
