Self-resetting wall with tuning-swing-friction compound graded energy dissipation function

Abstract

The invention discloses a self-resetting wall with tuning-swing-friction compound graded energy consumption function. , arc-shaped frictional energy-dissipating device. The bottom of the prefabricated wall is hinged through the sliding hinge support and the lateral stiffness is provided by the air spring. By adjusting the lateral stiffness provided by the air spring, the swing frequency of the prefabricated wall is controlled near the frequency of the main structure, thereby exerting the effect of energy dissipation and shock absorption. When the earthquake action is small, the tuned mass damper composed of prefabricated walls performs the energy-dissipating shock absorption of swaying. When the earthquake is strong, while the prefabricated wall is swaying and dissipating energy, the friction plates in the arc-shaped friction energy dissipating device contact each other and start to play the role of friction energy dissipating. The invention not only realizes the purpose of dissipating seismic energy in stages and reducing structural response under earthquake action, but also realizes the self-resetting function through steel strands and controls the residual displacement after the earthquake.

Description

Self-resetting wall with tuning-swing-friction composite graded energy dissipation function technical field [0001] The present invention relates to a self-resetting wall with a tuning-swing-friction composite graded energy dissipation function. by retarding The continuous solidification of the material continuously increases the prestress of the steel strands passing through the inner channel of the prefabricated wall, so that the prestressed tendons are function, so that the present invention can play a self-resetting effect under the action of earthquake. The lower part of the prefabricated wall is hinged and can be rocked By changing the lateral stiffness provided by the air spring to the prefabricated wall, the rocking frequency of the prefabricated wall can be adjusted to the main body structure The vibration frequency of the structure is near, so that it has stronger energy dissipation and shock absorption ability. Only rocking motion of prefabricated walls unde...

Problems solved by technology

However, this kind of method has strict requirements on the prestress size of the prestressed tendon. Too small or too large prestress will affect the normal performance of the self-resetting function.

Usually, when prestress is applied, the size of prestress cannot be accurately controlled
