Description
技术领域technical field
本发明属于建筑墙体构造技术领域，具体涉及一种波腹芯板预制混凝土装配式复合墙。The invention belongs to the technical field of building wall structures, and in particular relates to a prefabricated concrete assembly type composite wall with antinode core boards.
背景技术Background technique
现有技术中的钢筋混凝土剪力墙结构，因其整体性能好、抗侧刚度大、承载力高、抵抗风荷载及中小地震效果好以及防火性能优良等特点，是高层及超高层建筑结构中广泛采用的主要抗侧力构件。然而由于钢筋混凝土剪力墙刚度大，在地震作用下会承受较大的水平剪力，导致其裂缝较早产生，影响结构刚度及承载能力，且震后不易修复。另外随着建筑物高度增加，剪力墙轴压比不断增大，为了保证结构延性，当采用普通混凝土剪力墙时，需要采用较大墙体厚度才能满足设计要求，占用了较大使用空间，提高工程造价。The reinforced concrete shear wall structure in the prior art is a high-rise and super high-rise building structure because of its good overall performance, high lateral stiffness, high bearing capacity, good resistance to wind loads and small and medium earthquakes, and excellent fire performance. The main lateral force-resisting member widely used. However, due to the high rigidity of the reinforced concrete shear wall, it will bear a large horizontal shear force under the action of the earthquake, resulting in early cracks, affecting the structural stiffness and bearing capacity, and it is not easy to repair after the earthquake. In addition, as the height of the building increases, the axial compression ratio of the shear wall continues to increase. In order to ensure the structural ductility, when the ordinary concrete shear wall is used, a larger wall thickness is required to meet the design requirements, which takes up a large space. , Increase the project cost.
为了改善现有技术中钢筋混凝土剪力墙结构的延性，提高其在地震作用下的耗能能力，人们提出了多种改进措施，包括钢板剪力墙、开缝钢板剪力墙、加劲钢板剪力墙、约束钢板剪力墙等等。但却分别存在如下不足：In order to improve the ductility of reinforced concrete shear wall structures in the prior art and improve their energy dissipation capacity under earthquakes, various improvement measures have been proposed, including steel plate shear walls, slotted steel plate shear walls, and stiffened steel plate shear walls. force wall, restrained steel plate shear wall, etc. But there are following deficiencies respectively:
钢板剪力墙由于厚度过薄，在水平地震作用下会过早发生面外屈曲，在低周反复荷载作用下耗能能力较低，如果采用厚度较大的钢板又不满足经济性要求。加劲钢板剪力墙虽然避免了钢板剪力墙过早发生面外屈曲的情况，但其由于钢结构自身特性，防潮防火构造较难处理。约束钢板剪力墙是采用钢板剪力墙外挂混凝土板，避免钢板剪力墙较早发生面外屈曲的一种措施，对保证剪力墙具有一定耗能能力，外挂混凝土板与四周框架之间必须留有一定空隙以满足核心钢板的变形要求，因此约束钢板剪力墙与框架之间连接处的防水及防火构造较难处理，并且外挂混凝土板增加了结构自重，降低结构抗震性能。Due to the thickness of the steel plate shear wall is too thin, out-of-plane buckling will occur prematurely under the action of horizontal earthquake, and the energy dissipation capacity is low under the action of low cycle repeated load. If the steel plate with thicker thickness is used, it will not meet the economic requirements. Although the stiffened steel plate shear wall avoids premature out-of-plane buckling of the steel plate shear wall, it is difficult to deal with moisture-proof and fire-proof structures due to the characteristics of the steel structure itself. The restrained steel plate shear wall is a measure to avoid the out-of-plane buckling of the steel plate shear wall by hanging the concrete plate outside the steel plate shear wall. It can ensure that the shear wall has a certain energy dissipation capacity. A certain gap must be left to meet the deformation requirements of the core steel plate. Therefore, it is difficult to deal with the waterproof and fireproof structure of the joint between the constrained steel plate shear wall and the frame, and the external concrete slab increases the structural weight and reduces the seismic performance of the structure.
因此，现有技术缺乏一种对于既能承担竖向荷载，又能够抵抗水平作用的性能优良的抗侧力构件。Therefore, the prior art lacks an anti-lateral force component that can not only bear vertical loads but also resist horizontal actions.
发明内容SUMMARY OF THE INVENTION
