Database Formulation and Design Enhancement Initiatives for Vibration Assessment

项目简介用于地板振动评估的数据库制定和设计增强计划首席研究员：Linda M.Hanagan，Ph.D.，P.E.CMS Proposal#9900099许多轻质地板系统经历了由正常居住活动(如行走、跳舞、有氧运动等)引起的过高水平的振动。提高结构设计师提供可接受的地板系统的能力是本研究计划的主题。本研究的范围定义在四个研究主题下：1)楼层振动案例研究：正在进行至少10个楼层振动案例研究，以向包括PI在内的研究人员提供一个更广泛的关于现场钢地板系统振动行为的数据库；2)舞厅地板研究：几个备受瞩目的舞厅设施因其令人不安的楼层振动水平而受到媒体的负面关注。这些问题的原因正在调查中，并正在寻找可能的解决方案；3)在设计过程中使用计算机软件：正在进行研究，以研究通用结构设计和分析软件在楼板系统设计评估中的使用；4)补充设计标准：本研究旨在细化设计的特定部分，以帮助设计人员预测不可接受的楼层。

PROJECT ABSTRACTDatabase Formulation and Design Enhancement Initiatives for Floor Vibration AssessmentPrincipal Investigator: Linda M. Hanagan, Ph.D., P.E.CMS Proposal #9900099Many lightweight floor systems experience excessive levels of vibrationcaused by normal occupant activities such as walking, dancing, aerobics,etc. Improving the structural designer's ability to provide an acceptablefloor system is the subject of this research initiative. The scope of thisresearch is defined under four research subject headings: 1) Floorvibration case studies: A minimum of ten floor vibration case studies arebeing studied to provide researchers, including the PI, with a moreextensive database on the vibration behavior of in-place steel floorsystems; 2) Research on ballroom floors: Several high profile ballroomfacilities have been receiving negative attention in the press for theirdisturbing levels of floor vibration. The cause of these problems is underinvestigation and possible solutions are being sought; 3) Utilizingcomputer software in the design process: Research is being undertaken tostudy the use of general purpose structural design and analysis software inthe evaluation of floor system designs; 4) Supplemental design criteria:This research is targeted toward refining specific portions of the Designfor Walking Excitation criterion to aid the designer in predictingunacceptable floors.
