内容記述 |
The aim of this paper is to monitor the dynamic characteristics of masonry historical constructions by Structural Health Monitoring System （SHM）. Firstly, dynamic behavior of masonry historical building has been examined by microtremor observation. Natural frequencies and damping ratios for lower modes are also estimated by microtremor tests. Secondly, and most important, dynamic monitoring system has been installed on the buildings. From the recorded structural response under ambient excitation and to earthquakes, the dynamic characteristics of the buildings are identified using Operational Modal Analysis techniques. Further interesting aspect is the managing of such data with genetic algorithm to identify the damage and the variation of the engineering constants. By digitizing the state of the building with a measuring instrument, it is possible to easily and quickly make judgments on repair and renovation. |
