ABSTRACT
Load testing is the most direct way to verify the actual bridge condition which includes static load test and dynamic load test. Local or overall structural damage can lead to changes in the sectional stress, deformation or vibration. For the load testing of large-span bridges, it required many monitoring items and had strong correlation between different parameters. According to the traditional sampling method, it is difficult to achieve all parameters effective and reliable in a short time. Through the integration of wireless sensors and online monitoring systems, the load testing of Sutong Bridge during the operation period realizes the real-time and remote monitoring. It has outstanding advantages in improving the timeliness and ensuring the completeness of data monitoring. It can be used as a reference scheme for structural load tests of large-span bridges with similar time requirements and numerous monitoring parameters.
