Study of the Effects of Non-Structural Building Elements and Human-Structure Interaction on the Dynamic Behavior of Floors Subjected to Human MovementsMehdi Setareh, and Thomas M. MurrayPROJECT SUMMARYRecent advances in the development of higher strength materials coupled with more efficient construction techniques, more accurate computer-assisted structural analysis and design, new design methods, and more common use of long-span structures by architects have resulted in many floors that are susceptible to annoying floor vibrations due to walking, jumping, dancing, and similar activities.Even though this problem has been studied during the past thirty years, problem floors have become an increasingly common occurrence. These problems are mainly due to a lack of accurate definition of the dynamic parameters of floors, which in turn have caused poor correlations between the levels of measured and predicted vibrations by various design guides and particularly finite element analyses. Two major issues that have been mainly ignored in previous research are the effects of non-structural elements and the effects of the interaction of occupants and structure on the floor system. Most non-structural building elements are designed and detailed by non-engineers, mainly architects. Unfortunately, there is a lack of awareness of this problem among architects. The proposed research project intends to address the above problems. A two-story structure will be constructed at the Virginia Tech Research Center to act as a full-scale test model for a series of dynamic tests representative of the analytical excitations. It is estimated that the construction of the testing facility will be completed within the first eighteen months from the project starting date. A short pilot study to consider the effects of the non-structural elements and human-structure interactions will be conducted during the remainder of this two-year research effort.The broader impacts of this project are: First, the test structure will be a permanent center for the study of floor vibrations. Industries interested in the development of new products to address this problem will be able to use the facility to test their products. This will be a collaborative effort between the College of Architecture and Urban Studies and the College of Engineering of Virginia Tech. Students in the architecture and civil engineering programs will have access to this facility for their research projects, and help them understand the different aspects of this problem. The PIs will incorporate the results of this research into their architecture and civil engineering courses. All efforts will be made to involve students in the under-represented groups and minorities in this research. In addition, undergraduate students will be included through the NSF-REU program.

非结构建筑元素和人-结构相互作用对受人体运动的地板动力行为影响的研究mehdi Setareh和Thomas M. MurrayPROJECT摘要：高强度材料的最新发展与更高效的施工技术，更精确的计算机辅助结构分析和设计，新的设计方法，建筑师更普遍地使用大跨度结构，导致许多楼层由于行走、跳跃、跳舞和类似的活动而容易受到烦人的地板振动。尽管这个问题在过去的三十年里一直在研究，但问题地板已经变得越来越普遍。这些问题主要是由于缺乏对楼层动态参数的准确定义，这反过来又导致各种设计指南，特别是有限元分析的测量和预测振动水平之间的相关性很差。在以往的研究中，主要忽略了两个主要问题，即非结构因素的影响以及人与结构相互作用对楼板系统的影响。大多数非结构建筑元素是由非工程师设计和详细设计的，主要是建筑师。不幸的是，建筑师对这个问题缺乏认识。拟建的研究项目旨在解决上述问题。将在弗吉尼亚理工大学研究中心建造一个两层结构，作为一系列动态测试的全尺寸测试模型，代表分析激励。据估计，测试设施的建设将在项目开始之日起的头18个月内完成。在这项为期两年的研究工作的剩余时间里，将进行一项简短的试点研究，以考虑非结构因素和人-结构相互作用的影响。该项目的更广泛影响是：首先，测试结构将成为地板振动研究的永久中心。对开发新产品以解决这一问题感兴趣的行业将能够使用该设施测试其产品。这将是建筑与城市研究学院和弗吉尼亚理工大学工程学院的合作成果。建筑和土木工程专业的学生将可以在他们的研究项目中使用这个设施，并帮助他们了解这个问题的不同方面。pi将把这项研究的结果纳入他们的建筑和土木工程课程。将尽一切努力让代表性不足的群体和少数民族的学生参与这项研究。此外，本科生将被纳入NSF-REU计划。
