In recent years,earthquake breaks out frequently.It makes people pay moreattention to the safety of their living condition.Nowadays Cast-in-situ concrete hollowslab column structure is widely used in high-rise buildings as a new structure whichsatisfied people’s more requirement about room using function and it also has manyadvantages such as it’s more light and more convenient to construction. But now thatthis architecture in a high-rise building seismic performance is still in its infancy,Especially the a different inner mold arrangement、Approximate calculation of theseismic performance of the lack of a comprehensive and systematic understanding of thehollow floor.So I think it’s necessary to study the new structure concretely.Firstly, this paper introduced the earthquake hazards and the main methods to dealwith the damage which made the study on this kind of structure system significant.In thesecond,It presented the research status、technical characteristics, and the application ofCast-in-situ concrete hollow slab column structure and listed three stages of thedevelopment of seismic analysis theory.Thirdly this paper presented the finite elementprogram Strat and compares it’s results with the results of theoretical calculations andverified the accuracy of the procedure’s result.The second chapter analysed the different tube direction of the hollow slab columnstructure in high-rise cast-in-place and the earthquake response spectrum of theconverted common slab-column structure. It is proved that different tube directionsmade a trivial influence the seismic of hollow floor, the long span hollow tube canenhanced the Seismic performance,and hollow slab column structure’s seismicperformance is better than ordinary plate column structure under the same conditions.The third chapter analysed the elasticity and nonlinear time history analysis ofCast-in-situ concrete hollow slab column structure and Converted into ordinaryslab-column structure by three different kinds earthquake waves,found the weak part inSeismic performance of the structures and the great seismic differences of the samestructure in different site classifications. To verify the theory of the hollow plate columnwait ordinary plate column structure calculation errors exist, The board’s long-termdeflection difference.By the Performance-based static nonlinear Push-over analysis of the Cast-in-situ concrete hollow slab column structure and analysis of the Plastic hinge’s positions andorder,it is proved that the weak part in Seismic performance of the structures is agreewith the result above.And we also knew the structural element’s process of yield、destroyand collapse by analysesing the structure’s eventually damage curve.Finally, By the above analysis summarizes the results on the the hollow floor themechanical laws and are easily damaged parts, and propose specific seismic measures.Pointed thickened force Island area of concrete thickness is the most economical andreasonable methods; Lists and analyzes the specification and Atlas hollow floor structurespecific seismic design.
