英文摘要	In order to analyze the dynamic response mode of Kiewitt-6 single-layer reticulated shell with substructure under impact, a model of shell with steel pipe column for numerical analysis was established by using the ANSYS/ LS-DYNA program. Four dynamic response modes were put forward according to the features of dynamic responses. The influences of the impact energy, impact location, and stiffness of ring beams were studied. The impact test on the single-layer reticulated shell model with steel pipe columns was conducted. The dynamic stress, dynamic displacement and acceleration were measured and analyzed, and the damage patterns of impacted columns were studied. The results show that response modes are typically characterized by the damage patterns of impacted columns(slight damage, local dent, press-bend failure and shear failure).The dynamic response of the reticulated shell increases with the increase of impact energy with the exception of the response mode 4. The most unfavorable impact position is the central part of columns. The dynamic response of reticulated shell decreases with the increase of stiffness of ring beams. The numerical model was also proved to be reasonable by comparing the theoretical and experimental results. ©, 2014, Chinese Vibration Engineering Society. All right reserved.
