    摘要:

    通过2个不同角度的斜柱局部转换节点在竖向荷载作用下的静力试验以及有限元分析,获得了斜柱角度变化对该节点受力性能影响的基本规律.研究结果表明,斜柱角度的不同会导致转换梁和短肢剪力墙的应力分布有明显不同,斜柱角度越大,转换梁所受的拉力就越大,转换梁开裂就越早,结构承载力越低.相反,斜柱角度越小,短肢剪力墙内的应力分布要均匀些,转换梁开裂较晚,可以有效地抑制转换梁刚度的退化,结构承载力也越高.而且,从受力性能上来说,整个节点具有类似桁架模型的受力特征.

    Abstract:

    According to test results of two different angle specimens of local transfer RC joint from inclined column to Beeline-shaped short shear wall under vertical static loads and results of corresponding finite element analysis(ANSYS), fundamental behaviors of the joint are achieved for the change of the angle.The result indicates that there is much difference in the stress distributions of the transfer beam and short shear wall for different angles of inclined column, which shows that the larger angle, the more great tensile force and the earlier crack in the transfer beam and the lower capacity. Otherwise, the angle is smaller, the evener stress distributions in short shear wall, the later crack, the worse degenerate in the transfer beam and the higher capacity.Furthermore, the mechanical behaviors of the joint obviously followed the characteristics of a truss model.
