RESEARCHES ON DISTRIBUTION PROPORTIONS OF ENERGY RELATED TO MEMBER STYLES OF MULTI-RIBBED COMPOSITE SLAB STRUCTURES

The analysis of seismic energy responses of multi-ribbed composite slab structures ( MRSS ) was an important subject in the research and application field of MRSS． The distribution proportions of hysteretic energy related to component was a keypoint to realize the analysis of seismic energy responses． Based on the developed nonlinear numerical analysis model of MRSS，elasto-plastic time-history analyses were carried out on 150 examples， each of 15 MRSS under 10 seismic waves with large-earthquake level，which were designed according to current related codes and specifications． A series of formulas for distribution proportions of hysteretic energy related to component of MRSS were proposed and established． The comparative studies showed that the proposed formulas could be used in MRSS whose total number of storeies was less than 15．
