Abstract:Ground fissures have a huge impact on the safety of engineering structures.Ifprinciple of space avoidance is carried out in Ground fissures site with high intensity,it will waste limited land resources and make urban planning and construction restricted.The
modes of ground fissures site soil and the superstructure have been established by the finite element software ABAQUS in this PaDer. The simulation of multi.point loading of the structure crossing the ground fissure iS realized by inputting different seismic waves at
the boRom of the soil.Different locations about superstructure crossing the ground fissure have been set up which is based on differ—
ent conditions.Elastic.plastic time—history analysis on the superstructure which is in the earthquake could be made while different
seismic waves would be input from bottom of the soil.The elastic and elastic—plastic inter story drifls,the acceleration of the top,
floor shear,and intemal forces from the superstructure in different cases would be figured out.The perfolrmance of superstructure crossing the ground fissure under the uneven settlement and the earthquake would be shown clearly.The variation of dynamic re.
sponse of the structure crossing the ground fissure under different working conditions is discussed.Then,the most unfavorable posi.
tion about superstructure crossing the ground fissure would
