Abstract
This paper presents the refined technique of dynamic calculations for suspension
earthquake-resistant building. The improved design schemes of suspension buildings and
structures have been demonstrated. Two versions of suspension buildings have been analysed.
For the system with the building as a point mass suspension on the fixed bearing frame thread, a
system of Lagrange differential equations of the second kind has been derived. For the building
presented as a rigid rod with the length equal to its height, also suspended on the supporting
frame, the solution is performed using principles of dynamic calculations and methods of
theoretical mechanics.
Description
It has been demonstrated, that the horizontal force in the suspension building is ten times less
than the force in a traditional cantilever building, and that for the real horizontal stiffness of the
supporting frame the dynamic strains are far from resonant values. The possibility of adjusting
dynamic forces by regulating the stiffness of the supporting frame, length of the thread of
suspension and other parameters. The proposed calculation schemes are useful for the
preliminary calculations, and the finite design of the suspension building can be performed in
modern software packages (e.g., Ansys, Abacus, etc.).
