With horizontal shear component of intercolumn forces ignored, four equilibrium equations were formed, i.e., force equilibriums along the vertical direction, the sliding direction, Y axis direction, and moment equilibrium around Y axis. The equilibrium equations contained the actions of underground water, earthquake and supporting forces.
