Wind Vibration Reduction at Alicante Airport Control Tower, Spain
Abstract:The control tower of the Alicante airport is 47 m high and is composed of a concrete core, which has elevators, stairs, and a steel structure containing the technical, resting and the air-traffic control rooms. This steel structure is supported by a concrete pole with a tubular section, which is connected at different levels to the concrete core by means of steel trusses. This paper presents results of an investigation on the causes and remedies for vibrations in an air-traffic control tower. It has been shown that wind induced vibrations may disturb air traffic control for acceleration values which are lower than the thresholds as defined in ISO Standards. Besides small differences between theoretical and experimental results, buffeting analysis through numerical methods has proved to be useful to investigate the behaviour of tuned mass dampers and to adjust their design when applied to structures with well defined vibration frequencies.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
