Provedeni su proračuni križnog svoda crkve Sv. Petra i Pavla u Osijeku i katedrale u Đakovu te bačvastog svoda crkve Sv. Filipa i Jakova u Vukovaru. Razmatrana su djelovanja: stalno opterećenje, promjena sustava konstrukcije i horizontalno razmicanje oslonaca. Bila su dva pristupa. U prvom su rezultati proračuna naprezanja. Drugim se određuje model sloma konstrukcije za maksimalnu vrijednost horizontalnog razmicanja oslonaca i minimalno horizontalno ubrzanje tla od potresa.The authors analyse cross vault of the Sts. Peter and Paul Church in Osijek, cross vault of the Đakovo Cathedral, and barrel vault of the Sts. Philip and Jacob church in Vukovar. The following actions are considered: permanent load, change in structural system, and increase in horizontal spacing between the supports. Two approaches are used. In the first approach, the analysis results in stress values. The second is used to determine the structural failure model for the maximum value of increase in horizontal spacing between supports, and for minimum horizontal acceleration of soil due to seismic action
