Praca dotyczy wpływu sposobu numerycznego modelowania połączeń więźby dachowej i sklepień ze ścianami zabytkowych obiektów murowych na lokalny rozkład naprężeń w ścianach. Na wstępie uzasadniono potrzebę poszukiwań racjonalnego modelowania z uwagi na duże rozmiary modeli obliczeniowych lub błędnych wyników przy zbytnich uproszczeniach modelu. Przedstawiono aktualnie stosowane sposoby modelowania, w tym stosowanie sztywnych elementów skończonych między nieprzecinającymi się osiami konstrukcyjnymi elementów. Przeanalizowano cztery sposoby modelowania połączeń więźby dachowej i sklepień ze ścianami. Pierwszy sposób to opisanie elementów ścian i fundamentów elementami bryłowymi, żeber sklepień i więźby dachowej elementami belkowymi, a wysklepek sklepień elementami powłokowymi. Pozostałe sposoby 2-4 to opisanie ścian elementami powłokowymi. W miejscach połącznia ścian z więźbą dachową i ze sklepieniami w modelu No. 2 zastosowano fikcyjne elementy w postaci sztywnych powłok zorientowanych poziomo. W modelu No. 3 również wprowadzono fikcyjne sztywne powłoki poziome oraz lokalnie dodatkowo sztywne powłoki zorientowane pionowo, natomiast w modelu No. 4 wprowadzono tylko fikcyjne sztywne pionowe elementy powłokowe o skokowo zmiennym wysięgu. Najlepszym rozwiązaniem w zakresie rozkładu lokalnych naprężeń okazał się opis połączeń fikcyjnymi elementami powłokowymi w przypadku modelu No. 4. Takie podejście niewiele zwiększa liczbę niewiadomych, a urealnia wyniki naprężeń w rejonach połączeń w stosunku do pełnego modelowania bryłowymi elementami skończonymi.Bibliografia
