Abstract: The progressive collapse of the structure causes serious casualties and property losses. High?rise buildingsshould have appropriate ability to resist progressive collapse when accidental action occurs. The anti?progressive collapseability of the Haikou Twin Towers?South Tower was calculated and analyzed by using the demolition member method and theadditional lateral accidental action method in the code of Technical specification for concrete structures of tall buildings(JGJ 3—2010). The results show that the stress ratio of the remaining components satisfies the requirement for anti?progressive collapse. The dynamic elastic?plastic calculation method was used to check the calculation, and the resultsshow that the dynamic effect of the structure due to component demolition is not clear and there is no plastic behavior of theremaining members. Both methods show that the Haikou Twin Towers?South Tower has good redundancy and ability to resistprogressive collapse.

Keywords:Haikou Twin Towers; accidental action; anti?progressive collapse; demolition member method; dynamicnonlinear analysis
