CAREER: An Intelligent 3-D Base Isolation System for High- Tech Industrial Buildings

9702058常本研究项目的目标是开发一种智能三维基础隔震系统，旨在保护关键的高科技制造建筑及其内容。建筑物的内容通常比建筑物本身更有价值，包括精密设备、计算机、芯片或磁盘产品等。对于这样的高科技工业厂房来说，内容荷载与结构静载的比率通常很高。这些内容载荷的大小和位置频繁变化，通常会导致水平和垂直偏心，进而导致扭转、倾斜和摇摆响应的放大。所提出的智能保护系统旨在根据需要产生液体人造质量，以保持隔离建筑的基本固有频率恒定，并在任何隔离器过载时发出声音警报。智能系统还可以调整自己的属性，以自动微调隔离系统。如果智能系统在强震期间不必激活，以便在垂直推覆断层易发区或侧向走滑断层易发区都能有效运行。由创新系统设计、演示和研讨会组成的完整的配套教育项目OK也将实施，以吸引年轻人的兴趣，让本科生有机会沉迷于他们的学术好奇心，并为研究生在智能建筑设计领域的富有成效的职业生涯做好准备。***

9702058 Chang The goal os this research project is to develop an intelligent 3- Dimension seismic base isolation system aimed at protecting critical high-tech manufacturing buildings and their contents. The building contents, which usually are far more valuable than the building itself, consisting of delicate equipment, computers, chip or disk products, etc. The ratio of the content loads to the structural dead loads is typically high for such high-tech industrial plants. These content loads change in magnitude and location frequently and usually will cause horizontal and vertical eccentricities which in turn will cause ampliation of torsion, tilting, and rocking responses. The intelligent protective systems proposed are designed to generate liquid artificial mass as needed to maintain the fundamental natural frequencies of the isolated building as a constant, and also produce a sound alarm if any isolator is over loaded. The smart system can also adjust its own properties to fine tune the isolation system automatically. If the smart system does not have to be active during a strong earthquake in order to function effectively both for vertical thrust fault prone regions or lateral strike-slip fault prone regions. An integral, companion educational program O.K. consisting of innovative system design, demonstrations and workshops will capture the interest of young adults, to give undergraduates the opportunity to indulge their academic curiosities, and to prepare graduate students for a productive career in intelligent building design will also be implemented. ***
