摘要最近提出了一种新的集成控制系统，将联合收割机与质量阻尼器相结合，以提高建筑物的安全性和能源效率。双层幕墙系统用两层厚重的玻璃保护和隔离建筑物，空气可以在两层玻璃之间流动以通风。通过使外立面表皮能够运动，作者提出：（1）将它们用作质量阻尼器，以减少地震和风暴期间的结构振动和损坏;（2）调整外表皮和内表皮之间的差距大小，以控制通风率并提高能源效率。所提出的系统的协同作用可以导致结构安全，节能，并最终可持续的建筑。在本文中，两个结构控制策略-被动和主动-被认为是。首先，制定了正面阻尼器系统，随机和历史地震反应进行了模拟。最后，对阻尼器参数（刚度和阻尼系数）进行了优化。
AbstractA new integrated control system was recently proposed to combine double-skin facades and mass dampers in buildings to improve both building safety and energy efficiency. Double-skin facade systems protect and insulate buildings with two heavy glass layers between which air is allowed to flow for ventilation. By enabling movements in the outer facade skin, the authors proposed to (1) use them as mass dampers to reduce structural vibration and damage during earthquakes and wind storms and (2) adjust the gap size between the outer and inner skins to control the ventilation rate and improve energy efficiency. The synergy of the proposed system can lead to buildings that are structurally safe, energy efficient, and ultimately sustainable. In this paper, two structural control strategies—passive and active—are considered. The facade damper system was formulated first, and stochastic and historical earthquake responses were simulated. Then, the damper parameters (stiffness and damping coefficients) for p...
