Abstract:   (299 Views)
The combined conducted analytical, numerical and experimental studies to specify the factor of conformity in modular dynamic tests of frame type constructions are presented in the current report. It is well known that experimental studies are carried out by creating scale models of the real systems based on linear, mass, inertia, elastic and other scales. Resulting characteristics, describing the dynamic behavior of the scale models, after multiplying by the corresponding modules provide information about the behavior of the real ones. The factors of conformity to the own circular frequency and the amplitude of the forced vibrations, caused by kinematic sinusoidal interference, are analytically deduced in the report. The factors are applicable to one bay, one story frame with rigid external and internal links. The theory of the Deflection method of the Structural mechanics is used in the analytical determination of the coefficients. The numerical verification of the accuracy of the coefficients is realized through the appropriate software for dynamic analysis of structures, working based on the finite element method. Approximate experimental verification of the deduced dependencies is done through dynamic analysis of two models by Stand for modular dynamic tests of structures, subjected on seismic impacts. Developed methodology for determining the coefficients of conformity can be used for other class structures, including those with limited or infinite number of degrees of freedom. © 2016 The Authors.
