The Applied Of Steel-concrete Composite Open-web Plate Transfer Structure

Thick-plate transfer structure as one of the most important forms of transferstructure in tall buildings, can take out of the limit arranged by axes net, can be ensurethe building function of above and blow of the transfer floor to be realizedsuccessful.But as the buildings with thick-plate transfer floor have a bad effect ondynamic performance, thick-plate transfer structure can only be used in low intensitydistrict, hardly in high intensity district when should special project researching beforedesign and construction. Therefore studying a new formal transfer structure has a goodpractical significance, which has a similar function with thick-plate transfer structurecan not only solve the disadvantage of dynamic performance but also keep theadvantage to realize the building function of the traditional thick-plate transfer structure.The studies and achievements of this paper are as following:Improved the construction of the steel-concrete composite open-web platenowadays, take the “Software SAP2000” to set up the high-rise building models withthick-plate transfer floor and steel-concrete composite open-web plate transfer floor,then taking modal analysis and linear statics, compared and analyzed characteristic ofmode of vibration, interlaminar shear distribution, story drift distribution, and deflectiondistribution of transfer floor of two models, summarized the advantages anddisadvantages of steel-concrete composire open-web plate transfer structure.Studied the influence of cross-section of steel ribbed beam and shear key tohigh-rise building with steel-concrete composite open-web plate transfer floor by7×7 groups quadrature analysis. Compared natural period of vibration, characteristic ofmode of vibration, story drift and deflection of transfer floor, reached the influence ruleof either factor to massive structure.Statistics vertical and level seismic acceleration ratio under Ⅱsite condition by190groups actual measurement seismic data. Taking the statistic ratio to imitate verticalseismic acceleration curve, conducted the modal analysis response spectrum andmotive-force time-history analysis. Compared the influence confficcient of structuralcomponents hypogene by vertical geological process, check the uniformity of twoworks, summarized the influence rule of vertical seismic to high-rise building withsteel-concrete composite open-web plate transfer floor.Summarized and compared the calculate method of steel-concrete compositeopen-web plate nowadays. Accoding to the assume, give out a pratical calculate method.According to calculate the deflection of the example, compared the result ofserialization, finite element, and pratical calculation method, verified the feasibility andapplied range of pratical calculate method, gave a advise to select cell of finite element.Accoding to support connection, design the detail of construction of intermediateand gridding nodes which including hinge and rigid connection of open-web plate, andput forward the structural measures to strengthen the vertical stiffness of steel ribbedbeam.
