【摘要】：近年来,内填钢板剪力墙依靠其良好的承载力以及优秀的耗能性能,并且通过螺栓与框架梁进行连接方便地震后替换,已经作为抗侧力构件应用于高层钢结构建筑之中。本文在借鉴蝴蝶形钢板耗能器中起主要作用的蝴蝶形短柱的基础上,创新设计了带边缘加劲的单个蝴蝶形钢板剪力墙,作为整个钢板剪力墙直接放置在框架中,较大程度的节省了用钢量并保证一定的抗侧性能、延性和耗能性能。为了解单个蝴蝶形钢板剪力墙的抗震性能,本文采用控制变量的研究方法并采用有限元软件ANSYS,通过探究有无边缘加劲肋、不同形式的钢板剪力墙,和钢板的腰宽比、高厚比和高宽比等因素对钢板性能的影响,得出以下结论:(1)通过设置边缘槽钢加劲肋可以较明显提高钢板承载力及耗能性能,并且钢板平面外变形也可以得到有效的控制。(2)单个蝴蝶形钢板剪力墙较其他形式钢板剪力墙不易发生平面外失稳,表现出了更好的延性和耗能性能。(3)钢板腰宽比越小,钢板越不容易失稳,但其抗剪承载能力下降,综合考虑其承载力以及耗能能力,腰宽比宜取0.4最佳;钢板高厚比越小,钢板越不易发生平面外失稳,抗剪承载力越高,但耗能效率降低,综合考虑,高厚比宜取400左右;钢板高宽比越大,钢板越不容易失稳,且耗能性能越强,但是抗剪承载能力降低,对比综合考虑,高宽比宜取2.5—2.7之间。(4)根据性能最优的试件,通过改变几种常用的槽钢加劲肋尺寸,得出最优的加劲肋为[100×40×6号槽钢。(5)本文还研究了如果高宽比取为1.0时的单个蝴蝶形钢板剪力墙的加劲肋设置问题,建议采用钢板中间设置竖向槽钢加劲肋的方式,对钢板剪力墙的面外变形的限制以及耗能性能的提升有明显的效果。本文研究的研究结论可为这种单个蝴蝶形钢板剪力墙的推广应用提供参考。
[Abstract]:In recent years, because of its good bearing capacity and excellent energy dissipation performance, the steel plate shear wall has been used in high-rise steel structure building as a lateral force-resisting member, because of its good bearing capacity and excellent energy dissipation performance, and the connection between bolt and frame beam is convenient for post-earthquake replacement. On the basis of the butterfly-shaped short column which plays a main role in the butterfly-shaped steel plate damper, this paper innovatively designs a single butterfly-shaped steel plate shear wall with edge stiffening, which is placed directly in the frame as the whole steel-plate shear wall. The steel consumption is greatly saved and the side resistance, ductility and energy dissipation are guaranteed. In order to understand the seismic behavior of a single butterfly-shaped steel plate shear wall, this paper adopts the research method of control variables and the finite element software ANSYS, to explore whether there are edge stiffening ribs, different types of steel plate shear walls, and the waist-to-width ratio of steel plates. The influence of the ratio of height to thickness and the ratio of height to width on the performance of steel plate is discussed. The following conclusions are drawn: (1) the bearing capacity and energy dissipation performance of steel plate can be improved obviously by setting the stiffener of edge channel steel. The out-of-plane deformation of steel plate can also be effectively controlled. (2) the out-of-plane instability of a single butterfly-shaped steel plate shear wall is less than that of other forms of steel plate shear wall. It shows better ductility and energy dissipation performance. (3) the smaller the waist-to-width ratio of the steel plate is, the less unstable the steel plate is, but its shear bearing capacity decreases. Considering its bearing capacity and energy dissipation capacity, the waist-to-width ratio of 0.4 is the best. The smaller the ratio of height to thickness is, the less unstable the plate is and the higher the shear capacity is, but the lower the energy dissipation efficiency is, the better the ratio of height to thickness is about 400. The higher the ratio of height to width of steel plate, the less unstable the steel plate, and the stronger the energy dissipation performance is, but the lower the shear bearing capacity, the better the ratio of height to width is between 2.5 and 2.7. (4) according to the best performance of the test piece, the ratio of height to width is between 2.5 and 2.7. By changing several commonly used stiffener sizes of channel steel, the optimum stiffener is [100 脳 40 脳 6] channel steel. (5) the problem of stiffening rib setting of a single butterfly-shaped steel plate shear wall with the aspect ratio of 1.0 is also studied in this paper. It is suggested that the vertical channel stiffener should be installed in the middle of the steel plate to restrict the out-of-plane deformation of the steel plate shear wall and to improve the energy dissipation performance of the steel plate shear wall. The conclusion of this paper can be used as a reference for the popularization and application of this single butterfly-shaped steel plate shear wall.
