This paper is concerned with the optimal adaptive geometries of intelligent truss structures under dynamical loadings. The optimal geometry is attained by changing the lengths of some active members installed in the structure to obtain the maximum structural strength. Dynamical analysis by Newmark β method is introduced into the geometry optimization problem. The intelligent truss structure is assumed to be either fixed at the base or in a floating state. From the numerical examples, the following conclusions are drawn : (1) For an impact load, the largest stress exists in the place which is directly subjected to the impact and the geometry of the structure cannot improve the structural strength, (2) For a load acting for a long time, there exists an optimal geometry which provides a much higher structural strength than other geometries of the structure.
