There are two known ways to decrease damaging effects of earthquake or
wind initiated shear waves, which propagate in a building structure,
namely:
a) to dissipate the wave energy by means of damping devices; b) to absorb the resonant portions of the waves with the help of TMDs. Both energy dissipation and absorption assume an installation of special devices, often requiring a permanent maintenance, which makes such types of structural control rather expensive. |
| There is, however, a better choice: to disperse
the wave energy between a wider range of frequencies of oscillation
simply by properly configuring a building elevation thus preventing the
structure from resonant amplifications (click

research are:
· To investigate the influence of building elevation on its resonant ability. · To develop proper recommendations for architects and engineers. The research is analytical and will be accompanied with a limited testing. Its major product will be a practical method using vertical configuration as a means of structural control. |
