BRIGE: Integrating Structural Control and Double Skin Façades for Building Safety and Energy Efficiency

扩大参与研究启动助学金工程(Brige)项目旨在利用双层幕墙(DSF)作为建筑的质量阻尼器，以提高建筑安全和能源效率。DSF系统由两层玻璃组成，玻璃之间有一个空腔。与单一的玻璃外壳系统相比，该系统更具绝缘性，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蒙皮幕墙，可以在地震和强风期间抑制结构振动，而不会增加结构的额外重量(即独立的质量阻尼器)。增加了墙面的移动性，还可以带来调整建筑内气流和环境条件的创新方法。这项拟议的研究将产生一种新的、可移动的DSF系统，其安装的致动器用于影响阻尼器的运动，用于结构控制，并用于环境控制的蒙皮之间的空腔。首先对DSF-阻尼器连接结构和阻尼器参数进行了研究和优化。将开发主动控制策略，以最大限度地减少结构振动。此外，我们亦会研究DSF减震器系统的各种动作，以期最大限度地提高能源效益。准确理解结构控制和环境控制之间的协同作用将为建筑设计和运营带来变革性的转变。工程学和建筑学之间的综合、协同研究将延长建筑生命周期，同时提高能源效率，从而实现确保社会更可持续未来的更广泛目标。拟议的跨学科工作还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，这项研究可以吸引非工科背景的学生。在跨学院的合作中(土木工程和美术)，PI开发了一个建筑辅修课程，将帮助招收对建筑感兴趣的学生进入土木工程。鉴于建筑学专业的女性和非裔美国学生的比例高于工程学专业，招收有建筑学兴趣的学生将增加吸引未被充分代表的学生进入工程学专业的机会。

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.
