Progressive Collapse of Existing RС Structures due to Environmental Effects: A Numerical Approach for Strengthening by Ties
Апстракт
Existing old reinforced concrete (RC) buildings are sometimes subjected
to obligatory removal of some structural element‐members, e.g. columns,
and so to the risk of a progressive collapse. This happens due to various
reasons, which can concern changes of serviceability and requirements, or
environmental effects which cause strength degradation etc. In order to
avoid such a progressive collapse, a modification of the structural
response and a redistribution of internal actions can result to a
requirement for strengthening the remaining structure after the removal
of the degraded elements. The present study deals with such a case, which
concerns the computational analysis of framed RC structures under the
removal of some columns and the so‐induced requirement of a
strengthening by ties (tension only elements). The unilateral behaviour of
these cable‐ties, which can undertake only tension, is strictly considered,
and the response of the remaining historic structure strengthe...ned by ties
is computed. Finally, in a practical case of a framed RC structure, the
effectiveness of the proposed methodology is shown.
