Recently, by the broad can build technology co., LTD. (hereinafter referred to as the great building) completed & other; Prefabricated inclined supportThe steel structurebuildingtechnologyresearcheriodic and application subjectresearchResults and broad can build industrial prefabricated high-riseThe steel structureerformance is a Steel Structure Warehouse (hereinafter referred to as "research") & throughout; Recently by the housing and construction department of hunan province held in changshaexpertsThe review.

After serious discussion, the experts' research results on broad can be built to form four evaluation opinions. A brace is ambitious to build industrialization, prefabricated node reinforcing steel frame structure is suitable for below 100 metres, 8 degrees and more than 8 degrees fortification of high-rise steel structures. 2 it is project team using multiple open general commercial finite element analysisdesignSoftware of structural natural vibration period, the interlayer displacement, stress ratio of components, the structure overall comfort, comfort, stairs, comfort and so on carries on the analysis of the floor slab, comparing with the results of judgment, and support each other, show that this structure satisfies the requirement of specification mechanical and structural measures, elastic stress distribution of the seismic fortification intensity of 8. 3 it is through the pillars, motherboard, framework detailed finite element analysis of ultimate bearing capacitydesign2 times the left and right sides, the pillars of the load meet the design requirements, and has enough safety reserve. Motherboard with good vertical bearing capacity, can withstand 4.9 times the floor load design value, have greater security reserves; Framework of the overall capacity requirements, meet the most unfavorable load combinations damage location in the main girder chord and CHS, meet strong column weak beam, strong node weak component design requirements. Four is based on finite element analysis and test, multi-layer frame finite element analysis and experiment, proves that under the design load structure in elastic stress state, satisfies the requirement of stress; Under the effect of ultimate load, the model has entered the stage of plastic damage location in the beam of CHS, the ductility of the model has been fully made use of, produce ductile fracture, in line with the strong column weak beam, strong node weak component design principle, overall structure meet the design requirements. The structural system, structure, component meets the design requirements of 8 degree seismic fortification. Theoretical analysis shows that can meet the 9 degrees to flame. & other; Ambitious to build industrial prefabricated high-rise steel structure performance is a key problem & throughout; Project research combined with 30 layer structure of the pilot project, system, in-depth research, two aspects of theory and experiment to confirm each other, the research content, comprehensive research method is correct, the technology is Steel Structure Warehouse http://www.jingtabuilding.com/steel-structure-workshop.html, the detailed data, the conclusion is reasonable. Research results for the system further application and relevant specificationstandardrepare the support provides scientific basis and achievements.

Expert proposal, should be to further improve the design and construction of the system, expand the application scope of research system.

In addition to the advance of urbanization to construction in our countryThe steel structureBring market opportunities
