英文摘要	Firstly, establishment method of structural dynamic equilibrium equation and simplified calculation method of impact loads is introduced. Secondly, dynamic response law and failure mode of landing reticulated shell structure and with the lower support reticulated shell structure is simulated using ANSYS/LSDYNA. Lastly, the oblique impact tests for 3m span reticulated shell under different impact energy are done on the impact test bench. The results show: For landing reticulated shell, there are five kinds' of failure modes and the tests can verify the 3. Energy absorption calculation method of shell proves to be justified through comparison of numerical analysis results. With the impact point farther away from apex, displacement, axial force, energy, speed and other dynamic responses are relative small under the same impact action. Response from impact site to the whole shell is about 0.15 similar to 1.58ms. For reticulated shell structure when the lower column subjected to impact loads, there are 4 kinds' of failure modes and the tests can verify the 2. Structure strain energy cannot be ignored in the first impact process. Structure displacement and stress increases with the improvement of impact height. Response from impact site to the whole shell is about 1.2-6.1ms.
