Study on the dynamic performance of single layer ellipse lattice shell

WANG Xiuli,WANG Lei(School of Civil Engineering,Lanzhou University of Technology,Lanzhou730050,China)  
The parameter-oriented method is adopted to make program to build shell model,meanwhile geometry nonlinearity of the structure is considered as well as material nonlinearity;dynamics performance of the shell is studied by the method of superposition response spectrum and tested by time-history analysis,It is also discussed respectively that the two factor span and ratio of height to span have notable effect on the dynamics performance of the shell.The study provided us a full understanding of the dynamics performance of the shell,and theoretical base for progressive study on resistant seismic and vibration reducing.
