The invention also protects an application structure of the symmetrical integrated double-cylinder viscous damper for preventing out-of-plane instability, please refer to fig. 6, which mainly comprises a symmetrical integrated double-cylinder viscous damper 1 and an out-of-plane instability preventing support 2, wherein the symmetrical integrated double-cylinder viscous damper 1 and the out-of-plane instability preventing support 2 are respectively and fixedly arranged in a frame column (which is a main structure of a building), in the embodiment, the cross section of the frame column is square, an upper node plate 6 is fixedly arranged at one corner of the frame column, a lower node plate 8 is fixedly arranged at the other corner opposite to the upper node plate, the upper node plate 6 and the lower node plate 8 are diagonally arranged, the symmetrical integrated double-cylinder viscous damper 1 is obliquely and fixedly arranged in the frame column, a hinge bolt hole 10 at one end of the symmetrical integrated double-cylinder viscous damper 1 is fixedly arranged with the upper node plate 6 through an upper hinge bolt 7, in this embodiment, referring to fig. 4 and 5, the out-of-plane instability prevention support 2 is a channel steel with a U-shaped cross section, the out-of-plane instability prevention support 2 is installed at the middle position of two opposite sides of the frame column, a right side column node plate 4 is fixedly installed on one side of the frame column, a left side column node plate 5 is fixedly installed on the opposite side of the frame column, one end of the out-of-plane instability prevention support 2 is fixedly installed on the right side column node plate 4 through a high-strength bolt 17, the other end of the out-of-plane instability prevention support 2 is fixedly installed on the left side column node plate 5 through a high-strength bolt 17, a connecting hole 16 is also formed at the middle position of the out-of-plane instability prevention support 2, the connecting hole in the middle of the out-of-plane instability prevention support 2 is connected with the connecting hole 16 of the symmetrical integrated double-cylinder viscous damper 1 through the high-strength bolt 3.
The working principle of the invention is that when the structural node of the building is deformed (displacement, speed or acceleration), the viscous damper mainly generates displacement or speed for the structural node of the building because the viscous damper belongs to the displacement type damper, the displacement and the speed are transmitted to the viscous damper guide rod 11 through the guide rod connecting piece fixed on the frame node, the guide rod 11 performs piston motion in the cylinder body 21 filled with viscous liquid 12, and the acting dissipates the energy input by earthquake or wind load to achieve the aim of shock absorption of the structure, thereby improving the shock resistance of the building structure and protecting the main structure.
The out-of-plane instability prevention support is connected with a symmetrical integrated double-cylinder viscous damper through a high-strength bolt 3, and is fixed in the middle of a frame column through a right-side column node plate 4 and a left-side column node plate 5, and the reason that the support is fixed in the middle of the section of the frame column is that a large number of building structure experiments show that: when the frame column is deformed, the column bending point is usually located near the middle part of the frame column, and in addition, the section rigidity (relative to the viscous damper 1 of the invention) of the groove-shaped steel plate 18 forming the out-of-plane instability prevention support is not smaller than the rigidity specified by the formula 1, so that the middle node of the symmetrical integrated double-cylinder viscous damper 1 is ensured not to generate larger displacement as much as possible, and the out-of-plane instability phenomenon of the viscous damper 1 is prevented. In this embodiment, the out-of-plane instability prevention support uses Q345 normal channel steel.

Wherein Kz is the rigidity of the out-of-plane instability prevention support, T is the basic self-vibration period of the building structure, and Cd is the viscous damping coefficient of the damper.
The damper in the present invention is called a viscous liquid damper, but in the other dimension (mechanical dimension), also called a velocity-type damper, the damping force provided to the structure is related to the velocity of the rod moving within the cylinder. The formula is as follows: f=cv α Wherein F is the damper force provided by the damper, C is related to the comprehensive factors such as damping liquid characteristics in the damper, V is the speed of a guide rod in the damper, alpha is the speed index of the damper, and when the two ends of the guide rod and the cylinder body are connected with the frame nodes, the speed of the nodes is the speed of the nodes under the action of an earthquake. When the total strokes of the guide rods of the dampers are equal, namely when the motion speed of the damper is consistent with that of a single-rod damper and other parameters are the same, the damper in the invention has shorter time for one-time motion under one period, and can more rapidly dissipate the energy input by earthquake.
The invention relates to a series integrated viscous damper and an application structure thereof, wherein (1) firstly, a mode of connecting a support and an inventive series integrated viscous damper structure is additionally arranged on a frame column, and a certain relative constraint condition is added to the rigidity of the support, so that the restraint effect of the support on a viscous damper master cylinder is ensured, the normal operation of the viscous damper under the action of rare earthquakes and super typhoons is ensured, and the working stability of the viscous damper under the action of strong earthquakes and strong winds is enhanced. (2) The travel of the guide rod in the viscous damper is shortened through the mode that the damper is connected with the double cylinders in series, so that under the action of rare earthquakes and super wind load, the damper can provide faster damping restoring force for the node and enhance energy consumption capability under the condition that the deformation speed of the node is identical to that of the node and other parameters are consistent.
