Research On Shaking Table Test Of Structure With Arch Transfer Story

Arch transfer floor is a new type of transfer floor structure, which has major advantagesuch as space arrangement flexble，light weight,and strong integral rigidity. Literature [38]used Beijing Qian’an wave (site of categoryⅠ), Taft wave (site of categoryⅡ), Elcentrowave (site of category Ⅲ), Ninghe Tianjin wave(site of category IV) four kinds of seismicwaves, carry on structural elastoplastic time-history analysis, The analysis results show thatfor the purpose of rational plastic hinge distributed in the structure, and no collapse under theaction of severe earthquake, it may be suggested that the reinforcement of the bottom columnsshould be increased with the seismic fortification intensity7, and the coefficient ofenhancement of bearing capacity is1.3(site of categoryⅠ),1.9(site of categoryⅡ),2.2(siteof category ⅢandⅣ); meanwhile it may be proposed that the coefficient of enhancement ofbearing capacity of columns in the adjacent story above the transfer story is1.25, and that ofthe lower chord is3.5.On the basis of the former research, plan to bulid a7layer with arch transfer story at siteof categoryⅡ, an earthquake shaking table modelwas established based on similar principles，acceleration sensor was Layout of each layer in the model structure, research structuraldamage modes and damage theory, and pointed out that the weak parts of the structure, toverify previous studies have been. At the same time the use of SAP2000on structuralelastoplastic time-history analysis in order to research the maximal lateral displacement curve,the maximal story displacement angle and the maximal story shear under the seismic waves inthe Class Ⅱ site.The results show that the seismic responses of the structure is reasonable,the structure to meet the requirements of seismic design.
