MODAL ANALYSIS OF PARTIAL DOUBLE LAYER RETICULATED SHELLS

Reticulated shell has beautiful structure shape and excellent mechanics performance.It is one kind of space structures used extensively in recent years.This paper analyses the seismic performance on the optimum partial double layer reticulated shell under the present situation.The paper calculates the natural vibration on the optimum partial double layer reticulated shell by two different finite element methods, analyses the dynamic feature and gains the elementary parameters.
