基于多质点智能建造对高层建筑的抗震提升分析

Analysis of seismic lifting of high-rise building based on multi-particle intelligent construction

常规避震系统主要对建筑的质量块与阻尼器进行分析,从而忽略质量块间的相互作用。将调谐质量阻尼与多质点的智能建造技术结合,提升高层建筑混凝土结构的抗震能力,生成一种复合系统。该系统与其他3种系统进行对比,4种系统所保护建筑的自震频率分别为0.37,0.46,0.53,0.72 Hz,说明复合系统可以为建筑物的安全性提供更好的保障。系统的建筑震动下降98.7%,结果表明,提出的复合系统能有效提升高层建筑混凝土结构的抗震能力。

Conventional seismic isolation system mainly analyzes the building mass and damper,thus ignoring the interaction between mass blocks.Therefore,this study will combine tuned mass damping with multi-particle intelligent construction technology to improve the seismic capacity of concrete structures in high-rise buildings and generate a composite system.The system was compared with the other three systems.The natural frequencies of buildings protected by the four systems are 0.37,0.46,0.53,0.72 Hz,respectively,which shows that the composite system can provide better protection for the safety of buildings.The building vibration of the system decreases by 98.7%.The experimental results show that the composite system proposed in this study can effectively improve the seismic performance of concrete structures in high-rise buildings.
