THE VIBRATION REDUCING PERFORMANCE OF SINGLE-LAYER OVAL LATTICE SHELL WITH BUCKLING RESTRAINED BRACES
This paper reports on how to reduce earthquake responses for a single layer lattice dome installed with buckling restrained braces. The software of nonlinear finite element analysis ANSYS has been used and the single-layer oval Lattice Shell is modeling and analyzed with Buckling Restrained Braces(BRBs) on vibration reducing performance. On the assumption that the material modal of steel is the perfect elastic-plastic modal, the single-layer landing oval shell works under the effect of 3-dimension El-Centro and Taft wave during the course of the analysis. The result shows that the displacement response of the key-points and the force of the structure on the shell equipped with BRBs decrease evidently. This paper compares the different position of the BRBs in the single-layer landing oval shell as well, and puts forward the arrangement principle of the BRBs.
