Seismic Performance of Double-Layer Spherical Reticulated Shell with Replaceable Bar-Type Dampers
A new control method is proposed to improve the seismic performance of double-layered Kiewitt Spherical reticulated shells. The approach taken is to replace selected bars in the shell with passive viscoelastic dampers; thus, the grid of the shell doesn't need to be changed. Computational models of the shell with the eight different damper topologies are developed using ANSYS®. The seismic response of the shell is simulated to determine the performance of the various damper topologies. A parameter study is conducted to determine optimal values for the damping coefficient of dampers. Finally, the dynamic stability and failure modes of the shell are investigated through incremental dynamic analysis. If designed well, failure of the controlled shell is usually the result of a strength failure, rather than a dynamic instability.
