ABSTRACT:

The design of building structures is expected to provide sufficient structural robustness in order to reduce the risk of progressive collapse under extreme loading events. One way of checking the robustness is the Alternate Path method, which is achieved if the sudden removal of an element does not lead to progressive collapse. In order to verify that the structure meet this requirement, various methods can be used. Whereas the advanced non-linear dynamic analysis provides most accurate results, in practice, the non-linear static approach is more practical, but requires indirect consideration of dynamic effects using dynamic increase factors. This study investigated the factors that can affect the dynamic response of multi-storey steel frames following the loss of a column. Comparisons with current analytical approaches are also made.

Keywords:

Robustness, progressive collapse, column loss, catenary effect, dynamic increase factor
