The chapter is focused on the research of the seismic response of a cylindrical latticed-intersected-three-dimensional-beam-system (LlTDBS) reticulated mega-structure with double layer plane-plate grid substructure, using a response spectrum technique. At first, the distribution law of dynamic internal forces of members in a new structure is researched. Then, reasonable vibration modes combination of the vibration mode-decomposition-response-spectra method is discussed in the chapter. Seismic behaviors of the structure under different directional seismic loads are analyzed; therefore, the required components of seismic loads for an aseismic design are obtained in the chapter. The main structure bears all the loads and transfers them to the supporting structure. One substructure only bears the loads within the corresponding big grid and then transfers them to the main structure. Therefore, a new type structure of big grids filled with small grids is formed.
