TJD mild steel damper

Abstract

The invention provides a TJD mild steel damper which is also called as a TJD type mild steel damper. The TJD mild steel damper comprises an energy consumption element and a bearing element, and is characterized in that the energy consumption element at least comprises a core material part; the bearing element at least comprises a connection section which is divided into a first connection section and a second connection section, and at least one of the opposite end surfaces of the first connection section and the second connection section is provided with a groove adapting to the core material part; and the two ends of the core material part can be respectively inserted into the grooves of the first connection part and the second connection part, so that the first connection section and the second connection section are connected. According to the TJD mild steel damper provided by the invention, high-strength steel is adopted as the bearing element, so that the steel consumption quantity is reduced; slot plug-in connection is adopted, so that the core veneer waste material is reduced; the bending resisting ability is enhanced through one part of a sleeve extending to the bearing element; and sectional splicing of the damper in field is avoided and integration of the bearing element and the energy consumption element is realized.

Description

technical field [0001] The invention relates to the field of construction, especially the field of building structure support, and in particular relates to a mild steel damper used for support in a building structure system. Background technique [0002] Energy-dissipating shock-absorbing structures have been extensively studied and used since they were introduced into engineering circles. As a passive control method, energy-dissipating shock-absorbing structures are mainly based on setting specific additional energy-dissipating elements in the structure to input earthquake vibrations into the structure. The energy is directed to the energy-dissipating elements, thereby absorbing most of the input energy of the earthquake vibration and reducing the damage of the structure. At present, a variety of energy-consuming components have been developed at home and abroad, among which mild steel dampers are widely used in civil engineering because of their economy and practicability....

AI Technical Summary

Problems solved by technology

Mild steel dampers mainly achieve energy dissipation performance by providing good plastic deformation after steel yields. In the past, dampers used a vertical arrangement between the damper plane and the structural plane in order to improve their energy dissipation capacity. Therefore, the mild steel damper The initial stiffness is relatively small, which can only reflect its single energy dissipation performance
