【摘要】 密肋复合板结构的地震能量反应分析,是该类结构研究及应用领域的重要课题。作为实现地震能量反应分析的核心环节,准确确定结构中各类构件耗能需求的分配比例关系,是有效完成该类研究的重要基础。基于已开发的密肋复合板结构非线性数值分析模型,对满足现行规范规程设计要求的15个密肋复合板结构在10条地震波下的150个算例,进行罕遇地震下的弹塑性时程分析,提出并建立滞回耗能需求基于构件类型的分配比例实用计算公式。对比研究表明,计算式可用于15层及以下密肋复合板结构滞回耗能分配比例的计算求解。更多还原

【Abstract】 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.更多还原
