| Abstract: | The dynamic stability of single-layer cylindrical reticulated shells is discussed. By making use of El-centro earthquake wave, the time-history responses of the above structure to earthquake are obtained respectively. A detailed analysis on the dynamic stability and anti-earthquake of the structure is carried out. With considering various geometric sizes of single-layer cylindrical reticulated shells, the effects of rise-to-span and length-to-span to the structural dynamic stability are also analyzed. |
