摘要:
建立结构对称和非对称布置的框剪结构的三维有限元模型.采用3种中断条件和2种中断形式研究剪力墙的适宜中断位置和中断形式,并对各模型进行地震反应分析.结果表明:1)上部剪力墙全部中断,对顶点最大位移和振型周期的影响相对较小,但中断处楼层层间位移增大24.4%~41.5%,框架柱的平均剪力增大86.6%~137.1%,而部分中断则可避免层间位移及框架柱平均剪力产生较大突变;2)剪力墙中断后,非对称结构的层间位移、总剪力墙的剪力、框架柱的平均剪力沿结构高度的变化规律与对称结构的情况大致相同,而框架柱平均剪力增大略大于对称结构的情况;3)剪力墙中断位置由低至高的顺序为反弯点位置、最大层间位移角处、剪力为零处.其中,剪力墙在剪力为零处以上中断,框架柱平均剪力的突变最小.
Abstract:
The three dimension finite element model of both symmetrical and asymmetric frame-shear wall structure was established. Adopting three interrupt conditions and two interrupt forms, the suitable interrupt position and form of shear wall were studied, the seismic response of these models was analyzed. The calculation results show that: 1)the influence of whole upper shear wall interruption on the top maximum displacement and natural vibration period is relatively small, but the displacement between layers in intermitting position increases by 24.4%~41.5% and the average shear force of the frame column increases by 86.6%~137.1%. The partial interruption of upper shear wall can avoid the above abrupt change. 2)The variation of story drift, the shear force of total shear wall and the average shear force of the frame column along the height in asymmetrical structure is close to the variation in symmetrical structure, but the average shear force of frame column in asymmetrical structure is slightly greater than the one in the symmetric structure. 3)The shear wall interruption position from low to high is: contraflexure point, the position with maximum story drift angle and the position with zero shear force. Among them, the abrupt change of average shear forces of frame column is minimum when the shear wall is interrupt from the position with zero shear force to the top.
