Abstract
Apparatus for controlling deformation of an elongate member, such as a lattice girder, comprises a torque transmitting member, such as a hollow cylindrical tube, extending for the length of the girder coaxially with its longitudinal axis and fixed at one end to one end of the girder. The cylinder is free to rotate relative to the girder at its other end and is connected by hydraulic actuators to be rotated relative to the girder in response to the measurement of rotation between the ends of the girder. The relative rotation of the tube transmits torque to the fixed end and resists deformation of the girder.
