Abstract. After a review of the structural control implementations expected in the area of Civil and Architectural Engineering, these notes approach some associated research fields. Special care is devoted to the interdisciplinary character of the achievable progress and to the role played by laboratory testing in the scientific and technical development of structural control and structural control applications.

Introduction
In civil engineering, active systems for structural control are achieving an increasing importance in the fields of vibration attenuation and wind and earthquake hazard mitigation. But one deals with rather massive structures which are driven by mechanical devices with: i) the application oflarge forces; ii) fast reaction times and iii) relatively low accuracy. As a consequence, structural control applications in civil engineering are rather different from the implementations of control theory which have been developed in electrical engineering and applied mechanics. Also the required tools cannot be compared with the ones adopted for the control of space structures. The developments achieved in the areas listed above provide a help but do not solve the problems of structural control in civil engineering (Housner & Masri, 1994; Soong, 1991; Housner te al.,l997; Song & Dargush, 1997). This growing interest, and the need for a co-ordinated national and international research activity, led to the establishment of the US and Japan Panels on structural control research, under the auspices of the US National Science Foundation and of the Japan Science Council, respectively. In Europe there are not super-national responsible institutions. This suggested the European Association for the Control of Structures (EACS) to pursue a sort of research coordination which led to two main actions: CONVIB (2001), within the European Science Foundation and SAMCO (2001) within the European Union program GROWTH. EACS was founded in July 1993 and is linked to the International Association for Structural Control (IASC) which organises every four years the World Conference on Structural Control: Pasadena, USA, (Housner et al., 1994), Kyoto, Japan, (Kobori et al., 1998) and Como, Italy, (Casciati, 2002). EACS itself organised the European Conferences on Structural Control in Barcelona, Spain (Baratta & Rodellar, 1996) and Paris, France (Bourquin et al., 2000).The next meeting will be in Vienna, Austria, in July 2004.

Reference should also be done to the Journal of Structural Control, the EACS bulletin. The aim of this journal is to provide a forum in which survey articles and original research in the field of structural control can be communicated rapidly, towards a cross-fertilisation of information and ideas. An important aim is to achieve a balance between academic material and practical applications. The scope of the journal encompasses all aspects of structural control theory and te
