The monkey algorithm is applied to the sensor arrangement for continuous rigid frame bridge,and it is compared with other four optimal sensor arranging approaches.Firstly calculation steps of the monkey algorithm is introduced in detail.Secondly,with the background of a recently built long-span continuous rigid frame bridge,the sensor arranging schedules with various amount of sensors are provided by successive use of the five approaches and their effects are evaluated according to four estimating criteria.On this basis and by virtue of non-dimension technique,ageneral assessment system is built.The result verifies that the monkey algorithm is liable in the sensors arrangement for continuous rigid frame bridge.
