Influencing Factor Analysis of the Hysteretic Energy Responses for Seismic Frame Structures

Abstract eng:
One of the important issues in the research field of analyzing performance of seismic frame structures is the analysis of total input earthquake energy for seismic frame structure under earthquake action and hysteretic energy responses due to plastic deformation of structural components. Total input energy and hysteretic energy are influenced by various structural dynamic parameters and earthquake parameters, such as strength and stiffness of a structure, amplitude value, frequency quality and duration of an earthquake, and other many factors. The total input earthquake energy and hysteretic energy are analyzed by employing time-history methods and using a great deal of earthquake digital records as input data. Various different structural dynamic parameters and earthquake parameters are considered in the analysis of time-history method. The proportion of hysteretic energy to total input energy is calculated. The outcome of this analysis indicates that the structural dynamic parameters and earthquake parameters have not significant influence on this proportion above. The simplified analysis method of hysteretic energy for high-rise frame structures is proposed in this paper. The research result is research basis for analysis of performance of seismic frame structure.
