A temporary sensor network using 6 portable microtremor sensors is formed to estimate modal properties of a reinforced concrete office building under ambient vibrations. The building is almost always exposed to traffic vibrations due to railway trains and road vehicles. Therefore, ambient vibrations are composed of wide varieties of successive traffic vibrations. Based on the measurement results, it is shown that modal properties in translational and torsional vibrations of the building can be accurately estimated by an appropriate data acquisition and processing method even in noisy environments.
