EARTHQUAKE LOSS EVALUATION OF BUILDINGS BASED ON STORY EDP-DV FUNCTIONS

Abstract

Abstract

In order to simplify the performance-based earthquake loss evaluation process，the paper puts forward the method of earthquake loss evaluation of buildings based on story engineering demand parameter- decision variable ( EDP-DV) functions． Firstly，when considering the randomness of seismic response parameters，it can be achieved the distribution functions of story response parameters with the intensity measure given through incremental dynamic analysis． Meanwhile，the fragility functions are combined with loss functions to establish story EDP-DV functions． On this occasion，the damage measures are omitted and the storey not component is made to be a unit of account to simplify the earthquake loss evaluation process． Lastly，the relational function is established which is between seismic intensity and the buildings’economic loss by combing the distribution functions of story response with story EDP-DV functions． It is no need for dividing performance levels． The numerical example shows that the proposed method is feasible and reasonable to quantify the building’s seismic performance．
