Abstract: Crack uneven settlement is an unique geological disasters in Xi'an. As for the frame structure, displacement method was utilized to simulate the unevenness caused by ground subsidence cracks and the internal force of the frame beams and columns was analyzed based on the finite element analysis software SAP2000.. Research results show that the underlying structural beams and columns are the most disadvantaged members and the avoidance distance is 11 m to meet the conditions of the displacement in multi-frame distance in the crack site. This study would be useful for the design of ground hypospadias site framework.
