    摘要:

    为了解新疆某高层住宅在罕遇地震下的弹塑性行为,研究构件的损伤及屈服情况,判断结构的薄弱部位及薄弱构件,并对抗震设计提供建议。通过Midas-Building建立三维数值模型,对结构进行动力弹塑性时程分析。分析结果表明:结构最大层间位移角满足1/100限值的要求,大部分连梁出现损伤,主要受力剪力墙塑性损伤较小,结构无明显的薄弱部位。该工程虽属于高烈度区的超高层建筑,但通过合理的结构布置和相应的构造措施,能达到设计规定的抗震设防目标。

    Abstract:

    Elastic and plastic dynamic time history analysis of a Super high-rise residential buildings in Xinjiang was performed by Midas-Building to study the elastic- plastic behavior under the rare earthquake, to study the damage and yield of the components and to find out the structure of the weak layer of the structure and weak component to provide some suggestions for seismic design. Analyses results show that the maximum story drift ratio is less than 1/100 which fulfills the limitation requirement, most of the beam damage occurs, main shear walls suffer little plastic damage and no obvious weak parts of structure is found .Although the Super high-rise residential locates in the high seismic intensity zone ,but the structure can achieve the goal of seismic design requirements through the reasonable structural arrangement and calculation analysis.
