Description
技术领域 technical field
本发明涉及粘滞阻尼墙设计领域，具体涉及一种阻尼墙，尤其是涉及一种位移放大型双出杆粘滞阻尼墙。 The invention relates to the field of viscous damping wall design, in particular to a damping wall, in particular to a displacement-magnifying double-rod viscous damping wall.
背景技术 Background technique
消能减震技术通过在结构中某些变形较大的部位设置消能构件，或直接把某些构件设置为消能构件。在地震荷载和风荷载作用下，这些消能构件可快速进入耗能状态，消耗部分或大部分外部荷载输入结构的能量，从而减少结构主体的动力反应，避免或极大地减少结构主体发生破坏的可能性。 Energy-dissipating and shock-absorbing technology sets energy-dissipating components in some parts of the structure with large deformation, or directly sets some components as energy-dissipating components. Under the action of earthquake load and wind load, these energy-dissipating components can quickly enter the energy-dissipating state, consume part or most of the energy input from the external load into the structure, thereby reducing the dynamic response of the main body of the structure and avoiding or greatly reducing the possibility of damage to the main body of the structure sex.
传统的粘滞阻尼墙一般由刚接于上层梁底的钢箱体、刚接于下层梁顶的钢板组成，箱体内充填高粘度粘滞材料。当楼层发生相对位移或速度，内钢板在钢箱内的粘滞材料中沿箱体纵向滑动，产生粘滞剪切阻尼力，耗散地震或风荷载输入结构的能量，减少结构的动力反应。上述传统的阻尼墙存在如下的缺陷：首先是连接钢板的梁体受到极大弯矩作用；其次是层间位移速度有限，为增大阻尼力，需要极大的钢板面积；再次是层间位移量有限，限制了阻尼墙耗能能力。 The traditional viscous damping wall is generally composed of a steel box rigidly connected to the bottom of the upper beam and a steel plate rigidly connected to the top of the lower beam, and the box is filled with high-viscosity viscous material. When the relative displacement or velocity of the floor occurs, the inner steel plate slides longitudinally along the box in the viscous material in the steel box, generating viscous shear damping force, dissipating the energy input into the structure by earthquake or wind load, and reducing the dynamic response of the structure. The above-mentioned traditional damping wall has the following defects: firstly, the beam body connecting the steel plates is subjected to a huge bending moment; secondly, the interstory displacement velocity is limited, and in order to increase the damping force, a large steel plate area is required; thirdly, the interstory displacement The amount is limited, which limits the energy dissipation capacity of the damping wall.
因此，生产一种结构简单，操作方便，工作和运行效率高，牢固耐用，减震耗能效果好，使用寿命长的位移放大型双出杆粘滞阻尼墙，具有广阔的市场前景。 Therefore, produce a kind of structure simple, easy to operate, high working and running efficiency, solid and durable, good effect of shock absorption and energy consumption, long service life displacement amplified type double rod viscous damping wall, has broad market prospect.
