摘　　要：以某工程大跨度混凝土连廊为例,对大跨度混凝土楼盖舒适度的校核与改善进行了分析与研究。在连廊中采用多点调频质量阻尼器(TMD)消能减振系统,对连廊在减振前后各不利工况作用下的动力时程响应进行了数值分析。结果表明:多点调频质量阻尼器消能减振系统对于大跨度混凝土楼盖竖向振动舒适度的改善具有一定效果,可以在类似大跨度混凝土楼盖结构中进行推广。Based on a project with a 18 m-span corridor structure, checking and improving people＇s comfort on large-span concrete corridor structure is analyzed. The vibration decreasing system of multipoint TMD energy dissipation system is used in this corridor. The dynamic response of floor structure caused by the unfavorable load case before and after the vibration decreasing system is analyzed with FEA method. The results indicate that the vibration decreasing system of effect on minimizing the floor vibration structures. multipoint TMD-tuned mass damper energy dissipation system has some of large-span structures and can be applied to similar large-span concrete
