摘要:
不等高基础嵌固的山地掉层结构在地震作用中存在难以避免的扭转效应,合理控制参数的选择在扭转效应研究中至关重要。文中对山地掉层结构扭转效应研究中的基本控制参数进行了总结,介绍了刚心的不同定义,对比了不同定义的刚心对应的偏心率与掉层结构扭转效应的关系,并通过对系列山地掉层结构模型的数值模拟,讨论了扭转控制指标在山地掉层结构中的适用性。建议以“单一楼层刚度中心”定义的刚心对应的偏心率表征掉层结构的扭转效应,耦联周期比已不能作为反映结构扭转效应程度的指标,位移比限值在掉层结构的适用性有待进一步探讨。
Abstract:
The torsional effect is unavoidable for the structure supported by foundations with different elevations under the seismic action, and the selection of reasonable control parameters is crucial in the study of torsion effect. In this paper, the basic control parameters in the study of the torsional effect of the structure supported by foundations with different elevations were summarized. Different definitions of the stiffness center were introduced. The relationship between the eccentricity ratio corresponding to the stiffness center with different definitions and the torsional effect of the structure was comparatively analyzed. Also, through the numerical simulation of a series of structure models supported by foundations with different elevations, the applicability of torsional control index in the structure supported by foundations with different elevations was discussed. The eccentricity ratio corresponding to the stiffness center defined by Single floor CR is proposed to characterize the torsional response of the split-foundation structure. While the coupled period ratio should not be used as an index to reflect the torsional effect of the structure supported by foundations with different elevations, and the applicability of the limit of displacement ratio for the structure supported by foundations with different elevations needs to be further discussed.
