Seismic response of an existing RC building with core wall considering soil-structure interaction

215 σ.Εξετάστηκε ένα επταώροφο κτίριο αντιπροσωπευτικό των πολυκατοικιών της δεκαετίας του 1970. Το φρέαρ του ανελκυστήρα είναι το μοναδικό τοίχωμα που διαθέτει το κτίριο. Η θεμελίωση του κτιρίου γίνεται με μεμονωμένα επιφανειακά πέδιλα. Η συγκέντρωση των σεισμικών φορτίων στον πυρήνα αυξάνει τις απαιτήσεις στη θεμελίωσή του. Εξετάστηκε ο φορέας με τέσσεριςπεριπτώσεις έδρασης: ο φορέας πακτωμένος στη βάση, ο φορέας θεμελιωμένος με τα συμβατικά πέδιλα και δύο περιπτώσεις όπου ο φορέας θεμελιώνεται με υποδιαστασιολογήμενα, αντισυμβατικά πέδιλα. Έμφαση δόθηκε στη διερεύνηση της επιρροής του ενδεχόμενου λικνισμού του πεδίλου του πυρήνα στη σεισμική απόκριση του κτιρίου.Seismic response of an existing RC building considering Soil-Structure Interaction.Ανδρέας Α.

Reaching the Challenging Diagnosis of Complicated Liver Hydatid Disease: A Single Institution’s Experience from an Endemic Area

Background and Objectives: Hydatid disease (HD) remains a significant public health issue causing morbidity and mortality in many Mediterranean countries. Material and Methods: The present cohort study included 50 consecutive patients with liver hydatid disease who underwent surgery in a tertiary University Hospital. A total of 18 patients (36%) had a case of complicated HD, including simple communication of the cyst with the biliary tree (6 cases), rupture of the cyst into the biliary tree (6 cases), presence of a bronco-biliary fistula (2 cases), rupture of the cyst in the peritoneal cavity (2 cases), and rupture of the cyst and formation of a hepatic abscess (2 cases). Endoscopic retrograde cholangiopancreatography (ERCP) was pre-operatively performed on six patients. Results: The main clinical symptom presented was right upper quadrant pain in 16 patients (88%), which was associated with high fever (>39 °C) in 14 patients (78%). C-reactive protein (CRP) was the primary indicator of a complicated HD (p = 0.003); however, it was only elevated in 67% of cases. CRP was a more sensitive indicator of a rupture in the biliary tree cyst (p = 0.02). Computer tomography (CT) detected more cases (44%) of a complicated HD than ultrasonography (US) (25%); however, the difference was not statistically significant. Conclusions: For prevention and control of HD, a high suspicion of the disease leading to early referral to specialized centers, mainly in endemic areas, is required. Prior to surgical or percutaneous intervention, a combination of imaging and laboratory findings are essential in diagnosing a complicated case and avoiding unnecessary interventions
