Old existing industrial reinforced concrete (RC) structures are often subjected to
removal of structural elements due to degradation caused by environmental effects. So they are
in a risk of progressive collapse. In oder to prevent this risk, a strengthening by cable elements
(tension-ties) can be used. The probabilistic analysis of such RC structures under seismic
sequences is herein numerically investigated. The unilateral behavior of the cable-elements,
which can undertake tension stresses only, is strictly taken into account. Attention is given to
uncertainties concerning structural input parameters, common for such old RC structures
belonging to built Cultural Heritage. For their treatment, Monte Carlo techniques are applied.
The proposed methodology is explained in a numerical example.
Stare postojeće industrijske armiranobetonske (AB) konstrukcije često su podvrgnute
uklanjanju konstruktivnih elemenata zbog degradacije uzrokovane uticajima okoline, zbog čega
su u opasnosti od progresivnog kolapsa. Da bi se sprečio ovaj rizik, može se koristiti ojačanje
kablovskim elementima (zatezne zatege). Ovde je numerički istražena probabilistička analiza
takvih armiranobetonskih konstrukcija izloženim uticaju niza seizmičkih potresa. Strogo se
uzima u obzir jednostrano ponašanje kablovskih elemenata, koji mogu da podnesu samo
zatezna naprezanja. Pažnja je posvećena nejasnoćama u pogledu ulaznih parametara
konstrukcije, uobičajenih za tako stare AB konstrukcije koje pripadaju kulturnom nasleđu. Za
njihovo tretman primenjuju se Monte Karlo tehnike. Predložena metodologija je objašnjena na
numeričkom primeru.
