In this paper, based on the structural dynamic equations, the state space is introduced and the state equation of the dynamic response problem of the planar frame structure is derived. Based on this, an iterative calculation format is established for the structural dynamic response calculation. The numerical results show that the method has high accuracy and high solution efficiency.
