A cable dome composed of cables and struts is a new type of cable-strut system whose stiffness is provided by prestress.To investigate the structural behavior after one cable (strut) ruptured,dynamic method was adopted to simulate the process of cable rupture.The change of internal forces of other members and the final equilibrium position of the structure after failure of different members was investigated.The safety of the structure was evaluated by observing if the rupture of local cable caused slack of other cables and large displacement.The ability of anti-continuous collapses of the structure was judged by observing whether the rupture of local cable (strut) caused progressive failure of other members.The safety grade of members in different position was also distinguished.This study would benefit the normal service and maintenance of cable domes.
