Dynamic Response of Reticulated Domes under the Impact

Abstract:

As the study of the dynamic response of single-layer reticulated domes under impact, Numerical models for single-layer Kiewitt-6 reticulated domes with sub steel cube column were established by the ANSYS/ LS-DYNA program and a dynamic analysis were carried out. Four failure modes for the reticulated domes were put forward according as the dynamic response and plastic deformation. The parametric analyses on the dynamic response of single-layer reticulated domes with sub steel cube column under the impact loading are carried out, by changing the impact velocity, mass of impact object, size of impact object and impact location.The effects of these parameters on the response mode of the structures are investigated, and the distribution regularity of the response modes of the structures with different parameters is explained.
