Special attention is given to the diversity of rock mass behavior in relation to the different geometry of underground spaces, structural features of the geological deposits and the different stress conditions in which the underground spaces are located. As an example of carried out numerical calculations, the solutions for the state of stress and strain of underground spaces of the quarry of dimension stone on the exploitation field “Kanfanar-jug” are presented.","PeriodicalId":101599,"journal":{"name":"Numerički postupci.

Kod običnih je zidova došlo do otkazivanja nosivosti s pojavom karakterističnih ukriženih pukotina, dok se kod zidova ojačanih armiranobetonskom oblogom javlja prevrtanje krutoga tijela. Numerička analiza provedena je primjenom programa Diana 10.1 na makromodelima pri čemu je ziđe modelirano kao ortotropan i nelinearan heterogeni materijal koji može otkazati na smicanje, zatezanje ili pritisak.","PeriodicalId":101599,"journal":{"name":"Numerički postupci.

Analyses are performed by static pushover analysis and dynamic analysis. Material non-linearities are implemented as concentrated hinges at the structural elements. Relevant engineering demand parameters, obtained using different complexity levels analyses, are compared in relation to design criteria. Finally, building collapse mechanisms are described and critical structural elements are identified, in order to propose an efficient seismic retrofit method.","PeriodicalId":101599,"journal":{"name":"Numerički postupci.
