Description
技术领域Technical Field
本发明属于抗震结构体系领域，具体涉及一种防屈曲钢板剪力墙可滑动横向支撑固定装置。The invention belongs to the field of earthquake-resistant structural systems, and in particular relates to a slidable transverse support fixing device for a buckling-resistance steel plate shear wall.
背景技术Background technique
随着我国“低碳经济、绿色建筑”发展理念的提出，装配式建筑因具有节能环保、节约劳动力、机械化程度高、受气候条件制约小等优点，成为建筑领域发展的热点。它通过采用标准化设计、工厂化生产、机械化施工和信息化管理的方式，在信息互联方面表现得更为紧密。With the development concept of "low-carbon economy and green building" proposed in my country, prefabricated buildings have become a hot spot in the construction field due to their advantages of energy saving, labor saving, high degree of mechanization, and less restriction by climatic conditions. It adopts standardized design, factory production, mechanized construction and information management, and is more closely connected in information.
在高层建筑中，钢板剪力墙作为一种具有良好延性和耗能性能的新型抗侧力构件在国内外被广泛地研究和应用。但纯钢板剪力墙存在易发生面外屈曲、材料耗能性能未能得到充分利用、防火性能差及发生屈曲时噪音大等缺点。而防屈曲钢板剪力墙在面外混凝土盖板的保护下，能抑制薄钢板发生面外屈曲，充分发挥其材料性能，同时，盖板在钢板外面相当于保护层，提高了其防火性能。In high-rise buildings, steel plate shear walls are widely studied and applied at home and abroad as a new type of lateral force resisting member with good ductility and energy dissipation performance. However, pure steel plate shear walls have disadvantages such as easy out-of-plane buckling, insufficient utilization of material energy dissipation performance, poor fire resistance and high noise when buckling occurs. Under the protection of the out-of-plane concrete cover plate, the buckling-resisting steel plate shear wall can suppress the out-of-plane buckling of the thin steel plate and give full play to its material properties. At the same time, the cover plate is equivalent to a protective layer outside the steel plate, which improves its fire resistance.
现有技术在对防屈曲钢板剪力墙进行结构实验时，其横向固定通常是通过将MTS高载荷伺服液压作动器固定在结构反力墙上面，从而对实验框架进行横向固定。而现有的1.MTS作动器进行横向固定方式的工作量过大，所耗时间较长；2.MTS作动器进行横向固定时，会对实验框架提供额外约束。综上，通过MTS高载荷伺服液压作动器于对框架进行横向约束这种做法，将增大实验的前期工作量以及影响实验的进度。同时，由于提供了一个横向约束力，不利于薄钢板与混凝土盖板对于整体承载力贡献的研究。In the prior art, when conducting structural tests on buckling-resistance steel plate shear walls, the lateral fixation is usually performed by fixing the MTS high-load servo-hydraulic actuator on the structural reaction wall, thereby fixing the experimental frame laterally. However, 1. The existing lateral fixation method of the MTS actuator is too labor-intensive and time-consuming; 2. When the MTS actuator is laterally fixed, it will provide additional constraints on the experimental frame. In summary, the use of the MTS high-load servo-hydraulic actuator to laterally constrain the frame will increase the preliminary workload of the experiment and affect the progress of the experiment. At the same time, since a lateral constraint force is provided, it is not conducive to the study of the contribution of thin steel plates and concrete cover plates to the overall bearing capacity.
因此，现有的横向固定支撑装置易产生横向约束力，进而使得薄钢板与混凝土盖板的整体承载力不能准确测定成为了本领域技术人员亟待解决的技术问题。Therefore, the existing transverse fixed support device is prone to generate transverse restraining force, which makes it impossible to accurately measure the overall bearing capacity of the thin steel plate and the concrete cover plate, which has become a technical problem that needs to be urgently solved by technical personnel in this field.
