| Abstract [eng] |
Two models of interaction between acoustic field and building structure are investigated. The first – two dimensional model, where interaction between partition wall and acoustic medium has been modelled (given different conditions of the partition wall). The second – three dimensional model, which is used to analyze two storey floor–columns structure, applying acoustic and mechanical excitation, and different nonhomogeneity degrees of the structure. Possible mechanical system defect (reduction of rigidity due to floor flaw) has been modelled during the latter.The results showed that the same size and frequency of the acoustic load at harmonic excitation may lead to higher deformation of the structure having a defect. |
