Combined influence of the thermal effect and wind on pressure distribution in buildings

The paper deals with the pressure distribution in buildings under influence of the thermal effect and wind. The main subject is atrium building as one of the building form of rational use of the urban space, especially in the field of bussines, trade and other public activities. By application of the basic principles of the thermal and wind effects to the complex conditions of multistory atrium buildings, recognizing the influence of the atrium configuration on the pressure distribution has been enabled. The special attention has been paid to the variant solutions of the atrium space openings as potential natural ventilation by passive cooling and using the wind energy. Rad se bavi raspodelom pritisaka u zgradama pod uticajem termičkog efekta i vetra. Glavna tema je atrijumska zgrada kao jedan od graditeljskih oblika racionalnog korišćenja gradskog prostora, naročito u oblasti poslovanja, trgovine i drugih javnih delatnosti. Primenom osnovnih principa termičkog efekta i dejstva vetra na složene uslove višespratnih atrijumskih zgrada, omogućeno je sagledavanje uticaja konfiguracije atrijuma na raspodelu pritisaka. Posebna pažnja je posvećena varijantnim rešenjima otvora atrijumskog prostora kao potencijala prirodne ventilacije putem pasivnog hlađenja i iskorišćenja energije vetra.
