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。
Seismic energy response analysis of the multi-ribbed composite structure is an important issue in the research and application of such structures. As the core of the seismic energy response analysis, it is an important basis for the effective completion of this kind of research that the accurate determination of the distribution proportion of the energy consumption needs of all kinds of components in the structure. Based on the developed nonlinear numerical analysis model of the multi-walled composite plate structure, 150 numerical examples of 15 multi-ribbed composite plate structures meeting the design requirements of the current normative codes under 10 seismic waves are studied. Analysis, proposed and established hysteretic energy demand based on the component type of the proportion of practical formula. The comparative study shows that the calculation formula can be used to calculate the hysteretic energy dissipation ratio of 15-layer and below multi-walled composite structures.
