The "zero-deformation" intelligent control system of the building is connected to the driving system and the intelligent control system on the main structure; the driving system includes a driving force source, a driving device, a thermal resistor, a temperature measuring instrument, and an intelligent anchoring device; the driving force source adopts shape memory alloy material and is arranged outside the body of the structural member. The arrangement shape can be a straight line, a broken line or a curve, and both ends are anchored with the main structure by the intelligent anchoring device; The driving device forms a closed loop with the driving force source through wires for driving the driving force source. The thermal resistance sheet is fixed on the driving force source and connected with the temperature measuring instrument; The intelligent control system includes a stress state monitor and a computer control system. The stress state monitor is installed at the control section of the main structure and connected with the drive system through the computer control system to form a closed control loop. The computer analyzes and processes the stress on structural members. Information and controls the actuation of the drive system. The deformation of buildings can be accurately controlled.<o></o>
