According to the results of research on complex engineering objects, results were obtained that demonstrate significant deviations from the models of buildings and structures adopted as the basis for calculating seismic resistance and structural stability. First, it is the existence of reflecting seismic oscillations of the boundaries inside the building, when standing waves form a common field for the building as a whole and a local field for a part of the object. Secondly, a block structure of the object, when there are natural oscillations of different magnification with a different area of the object's coverage, when some blocks independently oscillate, they unite into one system. Thirdly, the existence of walls with double reflecting properties, which changes the field of standing waves. Fourthly, the complex geometry of the object causes fields of standing waves, e is described by two wave numbers. Experimental data show that in the theory of buildings, it is necessary to move to the models of nested resonators, models of coupled resonators, and the verification of models should be entrusted to the standing wave method.
