【摘要】 通过对框架结构弹塑性地震输入能量反应的分析,采用基于等效单自由度体系的振型分解能量求解方法,输入多条真实地震波,综合分析了地震动三要素对地震总输入能量的影响规律,通过实例计算表明:框架结构体系的输入能量与地震波的峰值平方成正比,地震波的卓越周期越大、持时越长,总输入能量也越大。更多还原

【Abstract】 Through analysis of response of frame structure to elastoplaslic seismic input energy,this paper adopts an equivalent single-degree-of-fredom system-based modal decomposition solving method,imputs some real seismic waves and comprehensively analyzes the influence of three elements of seismic ground motin on total seismic input energy.Examples’ calculation shows that the input energy of frame structure system is proportional to square of peak value of seismic wave,the dominant period and the duration of seismic wave the longer is,the total imput energy the larger更多还原
