Abstract EN
The beam string structure (BSS) is a type of prestressed structure and has been widely used in large span structures nowadays.
The adaptive BSS is a typical smart structure that can optimize the working status itself by controlling the length of active struts via certain control device.
The control device commonly consists of actuators in all struts and sensors on the beam.
The key point of the control process is to determine the length adjustment values of actuators according to the data obtained by preinstalled sensors.
In this paper, a static control algorithm for adaptive BSS has been presented for the adjustment solution.
To begin with, an optimization model of adaptive BSS with multiple active struts is established, which uses a sensitivity analysis method.
Next, a linear displacement control process is presented, and the adjustment values of struts are calculated by a simulated annealing algorithm.
A nonlinear iteration procedure is used afterwards to calibrate the results of linear calculation.
Finally, an example of adaptive BSS under different external loads is carried out to verify the feasibility and accuracy of the algorithm.
And the results also show that the adaptive BSS has much better adaptivity and capability than the noncontrolled BSS.
