Seismic Performance Design Of High Rise Building And Study Of The Weak Linking Slab

Taking high-rise building structure as the research object, an actual high-rise building’sseismic performance were analyzed, and the building was analyzed under the minorearthquake elastic dynamic time history analysis, medium strong seismic analysis and staticpushover analysis. Under small earthquake, time history average value is greater than theinterlaminar shear, on these floors construction drawing design, earthquake effect of responsespectrum method analysis will be the appropriate amplification,which can basicallyenveloping the results of time-history dynamic response analysis. According to the seismicperformance objectives, combined with the relevant formula in different seismic performancelevels of the structure bearing capacity of member design requirements in high regulation,calculation and Analysis on the performance of structure member, basically meet therequirements of seismic performance C of the structure.Based on a practical engineering high-rise building structure and the buihding modifedby the practical engineering building, A procedure for analysis of in-plan stresses of the weaklinking slab is proposed. The weak linking slab, connecting two main structures at its twoends, is the weak place of the floor. response spectrum method and time-history dynamicresponse analysis of The weak linking slab stress were taken. Time-history dynamicresponse analysis was taken to analaysis the weak linking slab of the high-rise buildingstructure in medium strong seismic analysis:The floor on the complex shape, due to weak joints in the transport and distribution ofhorizontal force, the important role of deformation coordination of the lateral force resistingsystem, should be the weak parts of the connecting plate to improve the seismic performanceindex.The engineering example shows that, the establishment of the block rigid models,using t time-history dynamic response analysis to determine the dumbbell shaped in-planstresses of the weak linking slab seems necessary. The response spectrum method analysis ofcomputing results are likely to underestimate them.
