Energy dissipation device based on tensile yield deformation control and working method

Abstract

The invention relates to an energy dissipation device based on tensile yield deformation control and a working method, and belongs to the field of seismic resistance of constructional engineering structures. The energy dissipation device comprises a shell, a piston arranged in the shell, a push-pull rod connected to one side of the piston and extending out of the shell, a reset mechanism connected to the other side of the piston and energy dissipation elements connected to the two sides of the piston and connected with the shell; when an earthquake occurs, the energy dissipation elements can be pulled to yield so as to reduce the earthquake action input to a wood framework, and the reset mechanism can generate pulling force or pressure to reset the energy dissipation element. In the whole stage, the wood framework is always kept in an elastic state and is not damaged. The energy dissipation device is installed at the included angle of the beam-column connecting joint of the wood framework, and the purposes of energy dissipation, shock absorption, lateral displacement reduction and prevention of large deformation and even collapse can be achieved; all the parts can be replaced, and machining, construction, installation and the like are easy; and the material source is wide, the cost is low, and wide popularization is facilitated.

Description

technical field [0001] The invention belongs to the field of anti-seismic construction engineering structures, and relates to an energy consumption device and a working method based on tensile yield deformation control. Background technique [0002] my country is one of the countries that suffered the most severe earthquake disasters in the world. In addition to the large number of earthquakes and the wide distribution of earthquakes, another characteristic is that the earthquake-prone areas are precisely some rural areas and market towns with relatively backward economic development, and the housing structures in these areas Weak measures, poor earthquake resistance, and the lack of professional design and construction guidance in construction have resulted in significantly higher earthquake damage than cities. Therefore, houses in rural areas in my country have become the weakest link in earthquake prevention and disaster reduction. In order to reduce the loss of the countr...

Problems solved by technology

The traditional beam-to-column joints of wooden frames are mainly connected by mortise and nail joints, which have limited joint strength and are prone to loosening; secondly, the construction is difficult and more dependent on the construction experience of workers; moreover, most structures It is non-recoverable and non-replaceable, and does not conform to the current idea of ​​a recoverable function shock-absorbing structure
