Abstract:
Four failure modes of reticulated dome (member slight damage failure, member broken failure, local dent failure, global dent failure) are generalized according to dynamic response, when single-layer reticulated dome under vertical impact load on apex. And that, failure members are all in impact zone. Dynamic response of failure members is given out. Then there are three states of load before failure of members: shear, bending and tension are listed in time order. Besides, four failure types of members are put forward basing state history before failure: shear, bending, bending and tension, tension. Based on analysis of energy transfer, the relationship among failure types of members, failure modes of reticulated dome and energy transferring are put forward: Failure modes of reticulated dome are decided by the maximum dynamic response. Then the maximum dynamic response is decided mainly by the energy in outer zone of reticulated dome. The ability of transferring energy can be judged by failure types of members in impact zone.
