屈曲约束支撑在整体双层柱面网壳中的减震性能分析

为了解屈曲约束支撑（BRB）在考虑下部结构的双层柱面网壳中的减震性能，通过大型有限元分析软件ANSYS建立跨度为50 m、下部为钢筋混凝土结构的双层柱面网壳，在该结构中应用屈曲约束支撑对其进行减震分析。计算结果表明:在强震作用下，屈曲约束支撑能够有效地应用在该结构中，其减震效果与使用屈曲约束支撑的数量和位置有关，只有将合适数量的屈曲约束支撑应用在恰当的位置才能取得最好的减震效果。

Damping Performance Analysis of Buckling-restrained Brace in Whole Double-layer Cylindrical Latticed Shell

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.
