STUDY ON SEISMIC PERFORMANCE LEVELS AND ALLOWABLE DEFORMATION VALUES OF SRC STRUCTURES
Combining with performance grades of reinforced concrete structures at home and abroad,the seismic performance of steel reinforced concrete (SRC) structures can be classified into four levels: normal service, temporary service, life safety and collapse prevention. The failure modes and characteristic of SRC columns are introduced, and limit states of the four seismic performance levels and their dominating parameters are put forward. On the basis of experimental results of SRC frames and columns, the story-drift angle limitation and range of crack width on the column end are obtained for four different seismic performance levels. Finally considering ideas of performance based seismic design, problems needed much further study about SRC structures are proposed.
