Abstract

The invention relates to the technical field of structural vibration, in particular to a stay cable damper and a combined damping device, and the stay cable damper comprises a cable clamp and a shell. Wherein the cable clamp is used for being clamped on a stay cable, a first container used for containing viscous materials is arranged on one side of the cable clamp, and at least one first inserting plate is arranged on the other side of the cable clamp; the outer side of the cable clamp is sleeved with the shell, one side of the inner side of the shell is provided with a second container allowing the first insertion plate to be inserted, and the other side of the inner side of the shell is provided with at least one second insertion plate inserted into the first container. According to the scheme, the problems that in the prior art, due to the damping characteristic and the installation position, the damping effect on the whole stay cable is not satisfactory, and the control effect is limited can be solved.

Description

technical field [0001] The invention relates to the technical field of structural vibration, in particular to a stay cable damper and a combined damping device. Background technique [0002] Cable-stayed bridges have been widely used in the field of bridge construction engineering due to their excellent structural form, beautiful structure, large span and flexible layout. With the development of science and technology, more and more new materials have been developed and new technologies promoted, and the number of ultra-long-span cable-stayed bridges with a span of more than 1000m is also increasing. As the main load-bearing component, the length-to-diameter ratio of the stay cable increases, and its stiffness and damping continue to decrease. It is very easy to generate large vibrations under external excitations such as wind, wind, rain, earthquakes, and vehicles, such as vortex vibration, galloping, and flutter. Vibration, buffeting, wind and rain induced vibration and p...
