Safety and Performance Enhacement of Structures Through Structural Control

该项目涉及受控结构的安全性和可靠性问题。本研究拟解决的技术问题包括：(1)抗倒塌可靠性增强的定量评估极端和中等强度的地震或风荷载，(2)提高控制系统可靠性的策略，即电子、机械部件和计算机软件；(3)成本效益权衡评价。本课程将研究被动和主动系统，以及这两种系统的组合(混合)。将使用基于概率的方法，以便包括不确定性的影响。将探索这些概念和方法在建筑结构、桥梁和电子输电设备中的潜在应用。

This project is concerned with questions of safety and reliability for controlled structures. The technical issues to be addressed in this research include: (1) quantitative evaluation of enhanced reliability against collapse under earthquake or wind loads of extreme as well as moderate intensity levels, (2) strategies for improving reliability of control system, i.e., electronic and mechanical components and computer software, and (3) cost-benefit trade off evaluation. Both passive and active systems, as well as combinations (hybrid) of both systems will be examined. Probability-based methods will be used in order to include the effects of uncertainties. The potential application of the concepts and methods in building structures, bridges, and electronic power transmission devices will be explored.
