摘　　要：随着现代建筑向大跨度、大悬挑、刚度小趋势发展,结构楼板的振动舒适度问题日益凸显,文章旨在探究结构楼板振动舒适度的控制分析方法。首先,通过模态计算楼盖结构频率分析并结合建筑图实际情况,合理分析结构薄弱位置;随后,结合结构楼板振动模型,运用有限元分析方法,对实际工程案例进行振动舒适度评估。基于理论分析和该工程实践,提出如何合理选取结构振型模态相对应频率和一系列振动控制措施,提高结构舒适度。研究不仅为结构楼板振动舒适度的控制提供了理论依据和实用方法,也为相关工程实践提供参考。With the development of modern buildings towards large spans,large cantilevers,and small stiffness,the issue of vibration comfort in structural floors has become increasingly prominent.This paper aims to explore the control analysis methods for vibration comfort in structural floors.Firstly,the frequency analysis of the floor structure is carried out through modal analysis,and the structurally weak positions are reasonably analyzed based on the actual situation of the architectural drawings.Then,combined with the structural floor vibration model,the finite element analysis method is applied to evaluate the vibration comfort of practical engineering cases.Based on the theoretical analysis and practical engineering experience,this paper proposes how to reasonably select the corresponding frequencies of structural vibration modes and a series of vibration control measures to improve structural comfort.This research not only provides theoretical basis and practical methods for controlling the vibration comfort of structural floors,but also serves as a reference for relevant engineering practices.
