- Abstract:
- In order to understand the damping performance of buckling-restrained brace （BRB） structure in the double-layer cylindrical latticed shell considering sub-structure, the general large-scale finite element analysis software ANSYS was adopted to establish the double-layer cylindrical latticed shell with the span of 50 m, lower part for the reinforced concrete structure. Meanwhile, the BRB was applied in this structure, and the damping analysis was carried out. The calculation results show that under the action of severe earthquake, BRB can be effectively applied in the structure. Furthermore, the damping effects associate with the number and location of BRB. Only the appropriate number of BRB is applied in a suitable place, the best damping effect will be achieved.
