Abstract:The equation of relationship between the top displacement and the rod angle of frame structure is established according to the principle of stationary potential energy. The formula of the top displacement under horizontal loads is deduced. The method is simple,applicable and accurate. It provides a new and simple calculating method for the top displacement of the frame structure. It is proved that the top displacement of the frame structure calculated by the D value method is a bit larger than the real result.
Keywords:frame structure； top displacement； principle of stationary potential energy
