【Abstract】 The structural analysis model of structure with mutational vertical stiffness was established with NosaCAD.In this paper,the seismic behavior of the structure under the frequent and rare intensity of 7 degree earthquakes was studied.Based on the analysis,the deformations,internal forces and damage patterns of the structure were investigated.At the same time,comparison between the model and the vibration table test was made.Finally,according to internal forces and load-carrying capacity or damage state of element,suggestions for improving the seismic design were given.更多还原
