摘要
以某大跨、重载、大层高、大体量多层PC锂电池工业厂房为例,研究消能减震技术在新能源和半导体产业工业厂房的应用,解决此类建筑采用常规混凝土框架方案所存在的局限性。结果表明:屈曲约束支撑的布置可以有效减小构件截面,降低预制构件生产及施工难度,大大提高结构方案合理性;结构在附设了屈曲约束支撑后,层间位移角有明显减小,满足减震目标;还具有良好抗震耗能机制和塑性变形能力,较大程度提高了结构主体安全性。可为现代消能减震技术在此类工程中的应用提供参考。
Taking a multi-storey precast concrete lithium battery industrial plant with Large span,heavy load,large height,large volume as an example,this paper studied the application of energy dissipation technology in the modern electric power and semiconductor facilities,and solved the limitations of implementing the traditional concrete frame system in such buildings.The results showed that the arrangement of buckling-restrained brace could effectively reduce the cross-section of components and the difficulty of production and construction,and greatly improve the rationality of the structural scheme;After the buckling-restrained brace were attached to the structure,the story drift was significantly reduced,which met the goal of damping;It also had a good seismic energy dissipation mechanism and plastic deformation ability,which greatly improved the safety of the structure.It gave some context for the implementation of related projects in modern energy dissipation technology.
