Abstract
With large opening floors,a frame structure,which is located in 7 seismic intensity (0.1 g) area,is an irregular plane building structure under the high seismic intensity area.In this paper,in order to study seismic behaviors of the structure in rare intensity of 7 degree (0.1 g) earthquakes,NosaCAD was used to perform elasto-plastic time history analysis.The results indicate that yielding hinges firstly occur in some beams under rare frequency earthquakes.Some yielding hinges appear at one end of some columns.The maximum inter-story drift of the structure can meet the requirement of the Chinese code.The structure satisfies the code requirements of no collapse under rare earthquakes.The irregular floors have some effect on deformation and damage of the structure.There are only translational responses for the rigid-floor assumed structure,but not only torsional response but also relative large component damage occur inthe elastic-floor assumed structure.关键词
