Fig. 12-8: An anti-symmetric frame subjected to an asymmetric load

Fig. 12-8 shows a simple anti-symmetric plastic frame unloaded (a) and carrying an asymmetrically concentrated load positioned close to the right hand column (b). It can be observed that the horizontal member deflects vertically and the loaded frame moves to its left. Again the movement is to the left for the load placed to the right of the centre line of the frame.
