基于损伤的累积滞回耗能与延性系数

Abstract

Abstract: A damage evaluation model was built based on the displacement ductility index from the point of seismic damage assessment in this paper. Test data of four destructive columns were used to value their damage state, which was in accordance with the new model. Taken the difficulties in the calculation of ductility index and the relation to the dissipated hysteric energy into account, a dependence curve of the index and the dissipated hysteretic energy was built.

Key words: Damage evaluation, Ductility index, Accumulated dissipated hysteretic energy, Earthquake-proof performance

CLC Number:

P315.7
