Model and Application on Displacement Calculation of Abutment by Considering Earthquake Effects


Article Preview

The response characteristics to the seismic action of displacement for abutment are the important part of security evaluation, earthquake resistance and disaster mitigation in the seismic region. This paper decomposes the displacement of abutment into the slip displacement and rotation displacement two parts, respectively proposes the translational and rotational displacement model of abutment and establishes the corresponding calculation formulas. The case analysis indicates that the response characteristics of abutment displacement to the seismic action are comparatively sensitive, in which the translational displacement appears positive response relationship with the acceleration of seismic, while the rotational displacement appears negative response relationship. However, it holds significant mutation from 0.5g to 0.6g for both of the translational displacement and rotational displacement. In other words, the seismic acceleration from 0.5g to 0.6g should be paid highly attention in doing seismic resistance design in the seismic region.
