Plane functional layout and total controlling plan of the general plan in the building always are abnormal. Furthermore the floor size and horizontal stiffness in the same floor are different tremendously, otherwise there are many dislocation floor in the same floor, according to different function in the same floor. Irregular plane in the building may happen according to the situation above. It is harmful to the force,, displacement and deformation in irregular plane. In order to research the essence of the irregular plane and avoid it, firstly the irregular plane is introduced, also we have distinguished stretch joint, settlement joint and, seismic joint according to the force theory of structure, and then we have used PKPM structural calculation program to build model, simulating the force in two improved models on the dead load, live load and horizontal seismic load, we have gotten the maximum displacement, maximum displacement angle, velocity, acceleration, shear force and moment, then we have analysised and compared displacement, movement and force. Finally, we have concluded:“Architectural design should be adopted by regular plane designing rule，it should not be adopted by irregular plane designing rule；for the building structure which body is complex and irregular plane，the designer should install the seismic joint in the appropriate parts according to actual needs，make the irregular building structure into several regular unit structure which could resist the horizontal load.”
