| 摘 要： | 针对某稀柱筒体结构,采用NosaCAD有限元软件建立整体结构分析模型。通过7度多遇和7度罕遇烈度下的弹塑性时程分析,研究了该结构的变形、内力、破坏情况的发展历程,计算结果表明,结构可以满足"小震不坏,大震不倒"的抗震设防要求;筒体构件破坏顺序较为合理,能较好的耗散地震能量。

| Abstract: | In this paper,in order to study the seismic behavior of the structure under the frequent and rare intensity of 7 degree-earthquake,a model is built with NosaCAD.Based on the analysis,the deformations,internal forces and damage patterns of the structure are investigated.The results of the study shows that there are no damages on the columns and few shear wall are damaged at the edge of bottom.The order and distribution of damages on components of the tubes are reasonable,which can dissipate some dynamic energy. |
