Abstract:Aiming at the limitation of the structural damage compute theory, the paper provides a new forming method of structure damage, and gives the computer step. Secondly, from the actual application, it discusses the important parameter, q. At last, this method is compared to the other three types of computer method of structure damage and prove the rationality of the new structure damage calculation, Also this method can provide some suggestion for structure analysis and design based on capability.
Keywords:RC structure; structure damage; frame structure; aseismic design
