The Seismic Analysis of Kiewitt Shell Based on the SMA Three-Dimensional Isolator

Abstract:

Article Preview

The SMA 3D isolator is based on a new intelligent material: shape memory alloy, which compensate the weakness in stiffness of the laminated rubber bearing. Through the seismic analysis of the kettlewell double layer shell, the truss horizontal and vertical internal force dropped obviously with the SMA 3D base isolator, especially the outer part which easily happened deformed damage and the structure internal force distribution is more reasonable, the deformation in harmonies, the lattice damage of weakness part is limited and offer efficient protection. Either the acceleration analysis, the peak acceleration reduced significantly and time history tends to slow, the isolating effect of the SMA 3D base isolator is prior to the laminated rubber bearing.
