项目摘要

This Broadening Participation Research Initiation Grant in Engineering (BRIGE) project aims to utilize double skin façades (DSF) as mass dampers in buildings for improving both building safety and energy efficiency. A DSF system consists of two layers of glasses with a cavity between them. Compared to a single glass skin system, this system is more insulating and its cavity allows airflow to help ventilate a building. By integrating mass dampers and double skin façades, structural vibrations can be dampened during earthquakes and strong winds without adding extra weight (i.e., separate mass dampers) to the structure. The added mobility of façades can also lead to innovative ways to adjust airflow and environmental conditions in the building. The proposed research will yield a new, movable DSF system with actuators installed to affect damper movements for structural control and the cavity between skins for environmental control. The DSF-damper attachment configurations and damper parameters will first be studied and optimized. Active control strategies will be developed to minimize structural vibrations. Various movements by the DSF-damper system will also be examined to maximize energy efficiency.The success of this research will improve building sustainability by enhancing building safety and energy efficiency. Accurately understanding the synergy between structural and environmental controls will provide a transformative shift in building designs and operations. Integrative, synergistic research between Engineering and Architecture will prolong building life cycles while improving energy efficiency, thus achieving the broader goal of ensuring a more sustainable future for society. The proposed interdisciplinary work will also increase diversity in Engineering on two fronts. First, it will expose current Engineering students to different disciplines. Secondly, this research can attract students with non-Engineering backgrounds. In a cross-College collaboration (between Civil Engineering and Fine Arts), the PI developed an Architecture minor program that will help recruit students who are interested in Architecture into Civil Engineering. In light of the higher percentage of female and African American students in Architecture than in Engineering, recruiting students with architectural interests will increase the chances of attracting underrepresented students to Engineering.
这项扩大参与工程研究启动补助金计划旨在利用双层幕墙作为建筑物的质量阻尼器,以提高建筑物的安全性和能源效益。DSF系统由两层玻璃组成,两层之间有一个空腔。与单一玻璃表皮系统相比,该系统更具隔热性,其空腔允许气流帮助建筑物通风。通过集成质量阻尼器和双层表面挡板,可以在地震和强风期间抑制结构振动,而无需增加结构的额外重量(即单独的质量阻尼器)。立面增加的机动性也可以带来创新的方式来调节建筑中的气流和环境条件。所提出的研究将产生一种新的、可移动的DSF系统,该系统安装了执行器来影响阻尼器的运动以进行结构控制,并安装了用于环境控制的表皮之间的腔体。首先对dsf阻尼器的附件结构和阻尼器参数进行研究和优化。将开发主动控制策略以最小化结构振动。dsf阻尼器系统的各种运动也将被检查,以最大限度地提高能源效率。这项研究的成功将通过提高建筑安全和能源效率来提高建筑的可持续性。准确理解结构和环境控制之间的协同作用将为建筑设计和运营带来革命性的转变。工程和建筑之间的综合、协同研究将延长建筑的生命周期,同时提高能源效率,从而实现确保社会更可持续发展的未来这一更广泛的目标。提议的跨学科工作也将在两个方面增加工程学的多样性。首先,它将使当前的工科学生接触到不同的学科。其次,本研究可以吸引非工程背景的学生。在一个跨学院的合作中(土木工程和美术),PI开发了一个建筑辅修课程,这将有助于招收对建筑感兴趣的学生进入土木工程。鉴于女性和非裔美国学生在建筑学中的比例高于工程专业,招募对建筑感兴趣的学生将增加吸引代表性不足的学生进入工程专业的机会。
