太原某体育馆改造加固设计

Strengthening and retrofit design of an existing stadium in Taiyuan

在太原某大(中)型体育馆的改、扩建设计中,对比不同阻尼比下的结构加固工程量确定加固方案,最终采用设置黏滞阻尼器的消能减震设计以使结构满足现行抗震设防要求,并显著减少了加固工程量。运用SAUSAGE结构分析软件对附加黏滞阻尼器的结构进行小震及大震下的时程分析及结构损伤评定,确定了消能减震结构在小震及大震下的附加阻尼比。并以此为基础进行上部结构的改造加固设计。此外介绍了基础及屋顶网架结构的加固改造设计。

In the strengthening design of a stadium in Taiyuan,the overall plan is determined by the comparison between the strengthening quantities of structures with different damping.As a result,dampers are settled in order to satisfy the current aseismic requirements and reduce the strengthening quantities.Time history analysis and structural damage assessment of the structure installed with dampers is executed by the nonlinear analysis software SAUSAGE,which is also determined the additional damping ratio of the energy dissipation structure.Based on this,the strengthening design of the structure is carried out.Furthermore,the foundation reinforcement and the grid designing is also involved.
