An Aseismic Design Model Based on Flexible Suspension and Lateral Elastic Support and Its Dynamics Analysis

Abstract

Abstract Suspension-type structures are of excellent seismic performance. It is expected to realize a better anti-seismic effect by integrating the elastic constraints that can absorb the seismic energy with the suspension-type structures. A structure consisting of vertical suspension and lateral elastic support was designed according to seismic damage characteristics for engineering structures, and some hypotheses were made to its stress conditions, which were properly simplified. Next, a basic mechanical model was established, followed by the structural dynamics analysis, so as to obtain the design value of elastic rigidity needed to ensure the minimum vibration amplitude. In the end, the seismic response characteristics and optimal aseismic design of the entire structure were acquired through an equivalent analogy. This study can be taken for reference in the new-type aseismic structural design based on the abovementioned model.
