STRUCTURAL CONTROL - PAST, PRESENT, AND FUTURE

This tutorial/survey paper: (1) provides a concise point of departure for researchers and practitioners alike wishing to assess the current state of the art in the control and monitoring of civil engineering st ructures; and (2) provides a link between structural control and other fields of control theory, pointing out both differences and similarit ies, and points out where future research and application efforts are likely to prove fruitful. The paper consists of the following sections : section 1 is an introduction; section 2 deals with passive energy di ssipation; section 3 deals with active control; section 4 deals with h ybrid and semiactive control systems; section 5 discusses sensors for structural control; section 6 deals with smart material systems; secti on 7 deals with health monitoring and damage detection; and section 8 deals with research needs. An extensive list of references is provided in the references section.
