Abstract
The cyclic loading pushover method which can simulate the real ground motion are suggested, and the target displacements of cyclic loading are discussed to overcome the drawbacks of traditional Pushover method which cannot consider the important seismic response of plane frames under earthquake, such as cyclic loading history, duration of strong motion, and the cumulative damage of structures. Through the comparison analysis of the story drift and hysteretic energy of plane framed structures gotten by adopting cyclic loading pushover method, traditional pushover method, and dynamic elastic-plastic time-history analysis method respectively, the conclusion that cyclic loading pushover method can better reflect the loading process with ground motion and the cumulative disruptive effect caused by hysteretic energy of structure can be obtained ,which provides some references for performance evaluation of elastic-plastic analysis of seismic structures.
