Research on Optimal Sensor Placement Method of Traditional Chinese Timber Dwellings Based on Multi-objective Monitoring
Traditional Chinese timber dwellings have high historical value, artistic value, and scientific value. The complex architectural form necessitates great challenge to the sensor placement. The case study of Number 21 Hall, a dwelling building located in Fujian Province (China), is investigated. An improved genetic algorithm is used for the multi-type and multi-objective optimal sensor placement of traditional Chinese timber dwellings. Firstly, the optimization objective function of multiple monitoring objectives is developed, considering the aim of the parameter identification, damage detection and information redundancy. Then, the improved genetic algorithm is used to search the optimal degree-of-freedom in the global space to determine the optimal sensor placement. Finally, the optimized sensor placement is determined. The results show that, the priority of acceleration sensors arranged on the roof beams of the main-room in Number 21 Hall is the highest, the priority of strain sensors placed at the foot of the column which located in junction area of the main-room and wing-room is the highest, and the tilt sensors should be placed at the beams near the top of columns. The research can provide scientific basis and valuable contributions to the optimal sensor placement in the structural monitoring of historical buildings.
