A thorough investigation and study on vertical and horizontal seismic response of double layer cylindrical lattice shells was made. The effect of different parameters on dynamic internal forces of lattice shells was analyzed. Some useful conclusions about regularity of the seismic performance were obtained, and some advice on aseisnuc design of double layer cylindrical lattice shells were given.
