The report considers the history of development of general theory of vibroacoustic simulation of distribution of broadband dynamic loads on bearing structures of buildings and structures. The following examples show the principles of construction of their direct and inverse vibroacoustic models in series and in parallel. It has been proven that the topology of the original schema is completely the same as that of its inverse model. This makes it possible to conclude that inverse vibroacoustic models of building structures are most convenient for design modeling of complex and multi-connected mechanical oscillatory systems. It is shown that vibration acoustic models for the first time allowed to create algorithms of automated design simulation of explosion resistance of bearing building structures in a wide band of numerous resonances of frequency reaction of the construction structure and its elements to explosive pulse loads.
